@instituteofhumananatomy: We opened up this cadaver and found a device still wired into the heart muscle. 🫀 The "confused heart" forgot how to beat properly, its electrical conduction system failed. So it got a pacemaker. You can see the lead (wire) running into the right ventricle and attaching to the heart wall. The generator in the chest fires an impulse down that lead to control rate and rhythm. Smart detail: the generator sits shallow on purpose, so swapping the battery is far easier than replacing the lead in the heart. 👉 Go deeper with our Exploring the Cardiovascular System eBook, link in bio. #LearnOnTikTok #TikTokLearningCampaign #LearnBiologyOnTikTok #STEMTikTokContest #LearnOnTikTokContest #pacemaker #cardiacanatomy #anatomy #humanbody #cadaverlab #anatomyandphysiology #medstudent #iohaanatomy
In a few weeks my class is going to dissect a heart, and I am so excited. The heart is at the top of my list of favorite organs

so if you have a pacemaker and you die will you lose consciousness yet your heart is still beating

It's so insane that doctors are able to literally insert a system into the heart. Big up doctors.

Does the lead penetrate the pericardium?

The confused heart needs one to beat.

I heard the heart is one long muscle that folded onto itself. Which kind of makes sense to me as everything is a fold in our body. And this folding can direct electrical signal and contractions.

might you post/discuss about the heart being a rolled spiral ? and show a true heart unrolled .. it seems that it follows the Fibonacci sequence for rolled over itself .. 🙏🇧🇷 .. thanks in advance
