I was worried at first because I have never experienced anything like this before.
I went to bed and the extremely fast heartbeat continued for some hours. (anonymous)I experienced palpitations in my 30ties and 40ties and found them frightening My GP reassured me and I had a normal ECG.
I attend a cardioligist every 6 months,and take tambacour and lanoxin.
I drink a lot of still get the odd episode,as the drs, call it.
Many many people reassured me it was ok and part and parcel of menopause.
I asked for referral to a cardiologist who informed me i have a type of atrial fibrillation which only occurs at night called vagal atrial fibrillation and it only happens every now and then.I think some people just cannot drink coffee at all, I find tea isnt as bad.
