The Heart: Electrical, Mechanical, and EKG

Feb 24, 2010 - I don't think so; narration says "...the pulmonic valve is between the R. atrium and the pulmonary artery." I am new to this; how can this be right? isn't that the tricuspid @ that location? Also, in diagram, it looks like the semi lunar valves both flex the wrong way when blood leaves the ventricles. Please clarify; exam tomorrow!

Feb 11, 2010 - The graphic is correct and what the narration said is correct as well.

Dec 12, 2009 - Great Vid! Question: The graphic appears to indicate that the pulmonic valve is in between the right ventricle and the pulmonary artery. The narration says otherwise. Please clarify in a reply if time permits.

Oct 13, 2009 - This is extremely helpful. Thank you very much for posting. A brilliant teaching aid indeed. I just have one suggestion, in case you plans to update this visual aid, perhaps you might want to use red and blue colors representing the blood flow. Red of course for the oxygenated blood and Blue for the un-oxegynated blood. Excellent video. Once again, thank you.

Jun 22, 2009 - hey i think you messed up at minute 5 and 31 seconds the heart does not have depolarize on the t wave

lilmizsweetface Says:

May 13, 2009 - thank you helped but if you could have added r wave is left ventricle contraction and s wave is right ventricle contraction that would be little extra info but very good vid!

Oct 19, 2008 - Thanks.I appreciate that you took the time and effort to make this possible.Hope you will make a better one next time and good luck on your cardio test.

Oct 18, 2008 - No hard feelings. This was the first video we ever made, and it was made on standard Windows movie maker using paint shop cut and paste techniques for pictures. The audio was from a very ancient microphone, and he had to yell to register volume. I have received some helpful hints though. Live and learn. When I'm not studying for my cardio test we will clean it up and rerecord.

FreezingCow Says:

Oct 18, 2008 - the diagram is alright but the way you talk realy makes it less interesting.Can you talk without that lazy slang..and there is always that disturbing sound you get from the mike which is realy irritating..(no hard feelings ya)just expressing my thoughts
