Subsidiary pacemaker exists in heart cells

[Finvola]

I knew that every cell in our hearts is capable of producing an electrical signal but I found this article interesting in its possible view of future pacemaking.

Interesting as you say, thanks Finvola. I’m trying to figure out how ‘growing’ [for want of a better word and if I have understood the paper correctly] a new pm in the RA is going to impact LA PVI and ablation.

Remind’s me of the old french witticism

Pagé’s paradox and Hamlet’s dilemma

Couldn't understand that either Badger - I think at the moment, the growing of a new node is primarily to take over from a non-functioning one and avoid an implanted pacemaker. How such research pans out may have implications for AF treatment in the future.

As I always tell people who worry about pace and ablate, every heart cell has the ability to trigger contractions so even with no AV node you wouldn't die if your PM stopped working. I suspect it may be many years before sufficient understanding of this "new" information will be of use to arrhythmia sufferers and of course since in AF it is cells doing their own thing rather than being wrongly paced, it probabaly won't help anyway. Nice idea though.

Amazing things these bodies of ours eh?

I found this very interesting because sometimes when I'm exercising when I have SVT my heart will suddenly switch to a normal rhythm after about 20 mins. then continue to beat normally for the rest of exercise period and afterwards. So now I'm wondering if another part of my heart is taking over. All the best

I had AFIB but always high rate, avge 165 resting but variable . I used to go running to get rid of the afib. 7 to 10 mins, and my hr dropped and remained normal after the run.

Unfortunately this trick stopped working after 20 months and a dozen succesful outcomes, as my afib progressed.
