So, a few weeks ago I passed out while sitting next to my wife - which made her panic. Short version of the story is that the episode was followed by influenza so may have been the beginning of that. Also an ECG I had shortly after passing out was normal. (FYI I am 49 and healthy).
But she insisted on going with me to my annual check up with my EP yesterday - and his recommendation was that I insert a Loop recorder mayoclinic.org/tests-proced...
To be accurate - he proposed it as an option and was neutral about whether I should do it as this is the first time I have had one of these incidents (passing out) and there isn't anything about it that shouts it was a cardiac issue ... but as I have stenosis of 2 valves and am in persistent a-fib he said if he was pushed into a yes or no he would lean to yes to inserting it.
It sort of depends on whether my medical aid will cover it (I live in South Africa) - but there is no real down side to having a regular record of my heart rate. The link above explains it well. I hadn't heard of one these before yesterday..
Within the last few months someone one this forum discussed this sensation they have where some limbs get warm for a short period (a minute or so). I sometimes get the same thing. My recollection of that discussion was some people thought it was caused by a low heart rate. I discussed this with my EP and he didn't think it was related to that - just sharing.
