hey and thank you very much for the answers.
my blood values are all good. electrolytes, thyroid, everything is fine. the long-term ECG showed extrasystoles. not many but they are there. I feel them too. luckily not very strong, but I still feel something that I didn't know before. but only when I relax. I don't feel any during the day or when exercising. the stress ECG showed the same thing. under stress my heart beats normally.
as I already wrote, I have had a lot of stress in my work and private life over the last 3 months. I almost had a panic attack 2 months ago. at least I think that's what it feels like. I've never had one before. I said to my wife at the time that something had to change because I probably couldn't take it much longer.
I've had the extrasystoles for 3.5 weeks. well, I'm on vacation now and have to look after myself. relaxation, exercise, music, family. nothing more otherwise my carnivore experience is going well. I'm continuing to lose weight, build muscle and feel good and fit. I hope my heart calms down again too.
