thank you a lot.I was struggling to understand the reentry mechanism but now thanks to you it's clear.The books i read didn't emphasize enough the refractary period and that's why i had such a rough time.THANK YOU

Eric's Medical Lectures Hi Dr Eric, could you please explain is the reentry phenomenon transient? Putting into consideration that after the first reentry has taken place, by the time the second reentry is about to take place, the fast pathway would have entered refractory period again (owing to a new electrical signal coming from the SA node/atrial pacemaker cells) and thus lead to a normal anterograde conduction again. Thank you very much!

Great video! I am though wondering wether the information at 10:53 is accurate. The slow pathway, with slow conduction has a prolonged action potential and thus should have a long refractory time? And the fast pathway, with fast conduction has a short action potential and thus a short refractory time.

Thanks for the question. I am 100% sure that the information is accurate. The conduction velocity and the refractory time are separate, independent physiologic parameters. The conduction velocity is determined predominantly by the function of sodium channels, while the refractory period is determined largely by potassium channels. When we talk about the slow pathway having a "short refractory time", that's not the refractory time of the entire pathway taken as a whole, but rather the refractory time of a single point along that pathway, as demonstrated in the animation.

One of the pathway needs to have long refractory and one pathway needs to have short refractory period for re entry to work. If fast conducting pathway had short refractory period than impulse will reach the pathway with long refractory period via distal connection so fast that the initially blocked pathway will still be blocked and re entry won’t be able to take place. That’s why he says in the video that the conduction through the pathway with short refractory pathway should be slow enough such that by the time it reaches the distal connection the initially blocked pathway has come out of its refractory period and re entry can take place.

Or....... if you're not a prehospital whacker with a sub $10/hr interest in the physiology of the quintessential mechanical organ of the human body, maybe watch it more times than you spent hours in EMT-P class.
