Hi everyone. So my dad has recently been in hospital after complaining of chest pains. He had a minor heart attack 12 years ago and has been on medication ever since. Whilst in hospital he had several ECG's and an echocardiogram, which revealed no significance. They also did bloods and concluded that the pain was non-cardiac (he was in hospital for a number of days whilst he waited to have all the relevant tests). They sent him home, thinking he had a case of pleurisy.
His blood pressure and pulse have been fluctuating quite a bit though. One of his medications is Bisoprolol which reduces his heart rate drastically; a normal resting heart rate for him is between 38-46bpm and has been the case for many years. But recently his pulse has been increasing a fair amount (up to the 70's and 80's, and today it even went above 100, albeit after being active outdoors), and he's been feeling lightheaded. Earlier on, I checked the pulse in his wrist and it was very irregular. It seemed to stop for extended periods of time (must have been 3 seconds or so), to start beating again very rapidly. It was quite disconcerting to feel, as I often feel my own heart beating irregularly, but it has never been as irregular as my dad's at that point.
At first I thought about the possibility of AF, but is this more indicative of something like Heart Block? Its very weird, and if I were to feel it in my own pulse I'd be straight to A+E again, but he doesn't seem too bothered by it. He's going to the GP tomorrow anyway.
Anyone have any similar experiences of such an irregular heart rate?
