Cardiac Conduction System and Understanding ECG, Animation.

(USMLE topics, cardiology) Please NOTE: this video talks about PQ segment, not PR interval, and this is NOT a mistake. You may have seen more of PR interval in text books, because it is used for ECG interpretation. But you should be able to find PQ segment too. These are 2 different things. The PR interval measures from the start of P wave. So PR interval = P wave PQ segment. To understand ECG, we intentionally use PQ segment as it represents one single event, easier to understand. The PR interval is used, however, to interpret ECG. You can see how to use PR interval to interpret ECG here (this is another one of our videos): This video and other related videos (in HD) are available for instant download licensing here: ©Alila Medical Media.
