Cardiology: Re-entry Circuits

[@winstonmiu]

This is one of the trickiest concepts to understand. Thanks!

[@desireegarza1802]

if I could like this a thousand times I would

[@stronger3381]

Keypoints: roads= conducting tissue (action potentials = cars). one road is fast- fast conduction and long refractory. the other road is wet, pothole = slow conduction, fast refractory. two cars run into each other = crash, everything stops. premature beat, splits going up and down, reenters the slow path. normal beat might not travel. Reentry circuits lead to tachycardia. Danger of ventricular fibrilation, if untreated. Treatment: Na+ blocker slows down the velocity. K blocker extends the refractionary period. Cardioverting electrical shock to the heart. Regular SA node beat must take over! could be located one location or the whole heart.

Analogies: make teaching harder, but make learning easier. Guess that's why so few lecturers formulate analogies: because doing so requires more effort than just reading from summaries on powerpoint slides. (I tried using analogies in my first year PBL, unfortunately, to an unreceptive group). Well done to the creators of this video.

[@PavanMehat12]

Rawdon Waller Absolutely you are spot on! It is harder for the teacher but makes life way better for the students 😁

[@ubcmedvid]

Thank you, Rawdon

[@leunghenna743]

I cannot thank you more for this super fun AND super clear explanation. Whoever made this video is such a good and passionate teacher. Thank you soooo much from the bottom of my heart.

[@ubcmedvid]

you are welcome!

[@MiguelNetocover]

im a medical student from brazil and i never saw an explanation so smart, thank you

[@ancatrif6329]

Thank you so much!! I read like 10 times and I couldn’t understand anything and then I came here and everything was clear under 5 minutes.

[@ubcmedvid]

so glad to hear that.

[@brooke48953]

I understand re-entry circuits now!! This was such an amazing demonstration on how they work, why they work, what they can cause, and why the treatments work. I'll always refer back to this analogy! Thank you so much!!

[@spartens89]

coming from a Biomedical Engineer grad student, this has been the best analogy and model for re-entry. thank you for the time you put into this

[@MultiGirl144]

You have no idea how thankful I am for this video!!Thank you!

[@poo5131]

you deserve 1 million suscribers thank you

So nice explanation. THANKS A LOT

[@kumaradarsh3983]

A faster car (faster impulse ) will stir more dust and so it will take more time for dust to settle and unless dust settles down , a car won't be able to make its way through the road (unable to conduct an impulse )

[@takekazuokmura1865]

[@anirudh-4112]

Awesome

[@김창훈의이마]

Sorry for too late comment wanting for reply, but why slow conducting tissue has short refractory period? Since both tissues are made with same function, I couldn't think what makes the differences.And thank you for nice video. My professor still uses this video for class😄
