This EKG animation was really great in that it shows the movement and electric pulse through the heart at the same time as the EKG moves. It even provides a sample EKG which is labeled with the P, T, and QRS complex.

This animation has the Cardiac Cycle, the EKG, and the Wiggers Diagram. The animation plays all at the same time. It also has a diagram of the heart, which shows blood pumping in and out of it. Everthing that we learned in class is basically on this animation. What I like about this animation is that there are manual controls to stop and play the animation. What I don't like about this animation is that it left out the electric pulses in the heart. When I am looking at the EKG, I do not see the pulse running through the heart at the same time, so I would need to follow along and draw it out by myself. Besides that, this animation is great to understand what we learned in class and to gain a different perspective and other insights to this topic.

I particularly like how straightforward this animation is. It gives a very clear idea of how the EKG relates to the cardiac cycle. However, I am disappointed in the quality of the animation as it seems almost hand drawn and takes away from the quality of the diagram. I would personally like to see a larger EKG diagram with better animation of the electric flow in the heart.

Click on physiology on the left side.
I really like this animation of the ekg graph because not only does it show the graph in respect to the cardiac cycle, but also I was able to go over each division of the graph with the cursor. I like how this animation allowed me to scroll over the graph and stop it when I wanted to see which phase it was in. The animation is very detailed, yet simple. It makes its point of coordinating the ekg graph and heart sounds with the cardiac cycle.
This animation has great sound effects and visuals. The website allows the viewer to stop and analyze each phase.

This EKG animation shows the cardiac cycle,EKG graph, pressure of the aorta and left ventricle,and the pressure & volume graphs.
This animation is good because it shows how the pressure, volume, S1 and S2 sounds, and EKG changes during the cardiac cycle. We can also pause the animation, and look at how each of these change step by step.
However, I think if this animation doesn't label each cardiac cycle, but only shows the motion of it, therefore, it is easily to get confuse by it. It is easier for us to understand if we can see how different things change step by step, and the animation also provide different important labels or explanation. If the graph of the heart can be more in details, (for example, shows how the blood flows), then it will be better.

I really liked this animation because it was really specific. It went into a direct explanation about what was going on alongside a heart diagram and an EKG wave. The only thing that I wish it had done was label the P, T, and QRS complexes.

I really like this animation because it showed a step by step process along with an explanation below it. Moreover, the labels on the heart were also very helpful because I was able to see what was participating during any phase of the EKG. Moreover, I also liked how the EKG wavelength and the movement of the current through the heart were animated next to each other, allowing me to relate the wavelength with different phases of the heart. However, the smaller animation of the EKG wavelength would be a little better if they added where the QRS complex and P or T wave occur.

I really enjoyed watching this animation. The animation is in slow motion with a voiceover, so the viewer can clearly see the relaionship EKG has with the cardiac cycle. The voiceover gives a lot of information about the electric pulses in the heart and the voiceover's information is written in the website. I liked all the information given because it was slow and understandable.

This EKG animation is not the best bu t it gives a good description of what EKG is and gives a brief description. It could work on it's animation and go more into detail by having the ability to pause and take it step by step to fully understand the cycle better.

I thought I would add this link because I find it to be rather helpful. The animation is simpler than some of the others and less detailed but I find that to be a benefit.
The animation clearly shows the electrical signal moving through the heart (red line) and right below demonstrates the part of the EKG that is occurring.
In addition, this animation shows the parts of the heart that are conductive as well as the parts that are not conductive. Definitely helped me visualize the process.
http://www.ecglibrary.com/norm.html
This link shows a normal EKG. It is helpful because it goes into great detail into what is normal. It gives exact measurements to the heights and widths of each wave. It also goes gives the seconds in which it is supposed to be on the screen. It explains the P, QRS, and T waves and where each of these are located. The best part about it is that it also provides abnormalities and it gives links to websites that explain these abnormalities for each wave. It was very helpful exploring these websites!
This EKG animation demonstrates what a normal beating heart would look like if an EKG was performed.This is a very different clip than the other youtube clip offered by one of my fellow classmates. I found it very interesting because it made it easier for me to identify which different circumstances on reading an EKG pointed out a problem with the way the heart functions. It provides information on what is happening in the heart and how it corresponds to the P wave, t wave, and QRS complex.

I found this diagram extremely useful in tying together the concepts of the cardiac cycle and the EKG. After watching the flow of blood through the heart a couple times, I paused this animation and pressed the button "step." While pushing this button, you can see each step of the cardiac cycle slowly, as well as where it corresponds with the EKG. As an added bonus, you can also see the pressure that is present in both the atria and ventricle at any given point in the cardiac cycle. Each step of the cardiac cycle is also labeled clearly above the animation. I am definitely going to keep this animation as a reference when it comes time to study for the exam!
This EKG animation shows more movement of heart than we learned in class. It shows more than ten heart movement such as Sinus rhythm, sinus arrest, VTach, and so on. It also provides beeping sound, more visual and auditory effects. Moreover, it explains what kind of movements they are showing in detail. The website also provides game so we can actually learn something. I really like this animation.

I also found this animation which shows the heart and the EKG at the same time.

This diagram is not the best of the EKG diagrams that are associated with the cardiac cycle because the diagram shows the cycle at a quick speed. To be able to fully digest this information of such complexity, it is important for the animation to go at a slower pace and be more comprehensive. It seems to lack important and detailed information for a beginning physiology student. I know I personally find this material rather difficult and I like a lot of the animations that have already been found for my own personal use.

I thought this was a very good animation. If you click the "view labels" button it will label many parts of the heart for you. You can also mouse over the "view blood flow" icon to see the flow of blood in relation to the EKG. Also at the bottom it shows the different waves of the EKG. All of this is really helpful in seeing what happens in the heart during different points in the EKG.

I really like this EKG animation because it clearly shows the user the EKG of a normal person as well as many other cardiovascular abnormalities with description of them explaining the differences between each.
However, I think this EKG animation would be better if it allows the user to play / pause and thus learn the various EKG steps by steps. It'd serve as a better learning tool that way.
Furthermore, I think it would be better if the animation also plays the sound of EKG associated with each abnormality.

Although this animation is somewhat long, it clearly explains the cardiac and EKG cycle simultaneously. You can stop, start, or rewind the clip at anytime if necessary.

This video has amazing three-dimensional visuals. I love that it shows the whole body, not just the heart, so we can see the connection between the EKG and the body. In addition, you can simultaneously see the pathways, heart contractions, and the actual ECG graph. The explanation is also very clear. At the end of the video, there are three ECG's comparing a normal heart to a heart with tachycardia, and a heart with myocardial infarction. These side-by-side comparisons help to show the abnormalities.
Just a few days ago I was talking to my aunt about some amazing new pregnancy test and how incredible these new break-throughs are. The test is called the Pink or Blue and was launched by the British company DNA Worldwide. The test allows the parents to find out the sex of the baby only six weeks into the pregnancy. To give you a better idea, usually a patient would go through a whole scanning procedure at about 20 weeks to find out the sex of the baby. The test is 98% accurate, but there is a huge debate over this new method because it might stir abortions in favor of male babies over female babies. The test is currently unavailable in China, India, and other countries where this may be an issue. The way the test works is, you send a sample of blood to the company and within 4-6 days, they tell you the results. They scan for fetal DNA in the mother's blood and if they detect a male specific Y chromosome, it is a boy--if not, it is a girl. Despite all the controversies, the doctors hope to use advanced genetic screening tests like these to detect early signs of chromosomal disorders such as Down Syndrome.

This EKG animation is just a simple outline of where each process takes place. If someone's having a hard time grasping the concept, perhaps this could help. However, this information is basic, so it lacks detailed information regarding the topic.
http://pennhealth.com/health_info/animationplayer/ecg_tool.html
I like this because you can actually play around with it. There are different things you can choose from. For example, you can choose to see what the waveform looks like when it is ventricular fibrillation or a ventricular asystole.
The only thing that it lacks is that it doesn't tell you where in the cardiac cycle your in or where the P, T, and QRS complex is at.

I thought that this animation was very good, if also very technical. It shows the electrical signal as it passes through the heart, causing it to contract, with the EKG following each contraction. The heart digram was very detailed, much more so than we have dealt with in this class, but it does not take away from the animation. Also, the EKG is color coded so you can tell which sections are p, q, r, s, and t. Finally, to the side it shows step by step what happens in the heart. The only thing I did not like about this animation was that the actual sections of the EKG were not labeled, however, if you have some background in EKG's, it should not be hard to differentiate because each section is a different color. Overall, I thought this was a very detailed and informative animation.

This animation of the Cardiac Cycle shows the simple stages of the Cardiac cycle. Following with this link
http://library.med.utah.edu/kw/ecg/animations/ecg.html
it shows the animation of the EKG as the cardiac cycle progresses within its own cycle. It shows the progression and cycle of the P QRS T modes, and it helps you to understand how the EKG reacts according to the actions of the heart. Interesting animations that can easily help you to understand the materials that we have been discussed, and it helps us to visualize EKG cycle into a real action. I really recommend the second link for all the students whom might have trouble of relating the EKG diagram with the cardiac cycle.

I like this animation of the EKG and the cardiac cycle because not only does it list the definition of what an EKG is, but it also takes you step by step of how electrical signals cause the heart to contract. I also like the fact that it tells you when the LUBB DUBB sounds take place during the cardiac cycle. By labeling all the parts of the heart and writing a simple, easy to understand description of what is happening during each step really helps the student understand what is going on.
It looks like most of the good ones have been taken, but I think I was able to find one that it doesn't look like anyone else has posted yet. This one is nice because it shows the heart and the EKG going at the same time, although the picture could have been a little better.

This link is useful because it shows three different animations of the electrical signals moving through the heart. I especially like the moving animation which shows the direction of the electrical signals in each part of the heart. This moving animation is coupled with an EKG which shows the P wave, QRS complex, and T wave and also the points at which different parts of the heart are depolarized and repolarized. I would have liked to see more animation of actual contractions of the heart, but this link does well in showing the direction of blood flow and defining the cardiac cycle.

Here is an animation that talks about the PR interval. However, it pertains to the whole EKG and Cardiac Cycle. I like how it shows a normal EKG and then goes into how it relates to the heart. I also like how it is detailed, talking about how the EKG starts with the SA node and AV node then goes into the ventricles. The main thing I did not like about this animation was how it felt incomplete. I wish there was more to it.
http://www.youtube.com/watch?v=nK0_28q6WoM&feature=related
I enjoyed this animation for several reasons. Not only did it show the path of the impulse in the heart, but it also talked about the different disorders involved with ekg which we learned about in class. This animation showed pictures of those disorders as well. Also it discussed about the p-wave, t-wave, and QRS Complex.
http://anatimation.com/cardiac-cycle/cardiac-cycle-animation-and-diagram.html
I'm not sure if someone has used this diagram or not; however, I think it's a very good one that covers many aspects of the cardiac cycle and the EKG. This animation demonstrates how the heard moves in one heartbeat and it also shows the pulse of the electrical movement throughout the heart. Also it recognizes the change in pressure in the heart. Moreover, it recognizes Atrial pressure and ventricular pressure.
Weaknesses are that this diagram is that it does not point out the QRS complex, etc. Also, it only verbally recognizes the phases of: ventricular diastole and ventricular systole. To make this animation more complete. more specific aspects such as the QRS complex could be helpful.
This EKG anitmation is very interesting because you can click which each wave individually. There are also 3 different leads which show different types of each wave. You can also click which wave you would like to have display. For example, if there is a specific wave that you would like to see, such as the QRS wave, it can display the wave starting from the QRS. I enjoy the fact that you are able to fast forward and rewind the pictures of the wave.

I found this animation to be very helpful in explaining exactly what is happening in the heart during P, QRS Complex, and T. The animation gives a picture of a heart and it's movement, while below an animation of an EKG is corresponding to the heart's movement. I would suggest that anyway having trouble figuring out what is happening during P, QRS Complex, and T should watch this video. The only problem with the video is there's no sound or text to go along with it.

I liked how this website was able to explain the EKG in how it is used to measure the electrical activity of the heart especially providing various cool animations that seem to come to life. It explains the roles of the P,T, and QRS complex in the heart's electrical activity in detail. I also find it interesting in how it talks about the certain types of charges that take place in the heart including the Einthoven's Triangle.

This Animation is an entire movie that discusses the EKG and how it relates to the heart. It walks you through the electrical system that causes your heart to beat and is very clear and concise. This movie will help a lot and would be a good study tool. It shows you how and where the signal is in the heart, and where it is on the EKG to further explain the correlation between the electrical signal and the EKG diagram.
