Hi there! I am a 60yr old female and for the past 4-5 weeks I have been experiencing fast heartbeats especially when I am lying in bed at night I can hear it beating like heavy drumbeats - and I notice I have been getting tired aas well- e.g. I can't stay up as late as I used to and feel really sleepy all of a sudden at times I can't keep my eyes open - apart from this I am healthy -blood pressure and sugar levels fine but cholesterol just a bit on the high side. I weigh 65 kgs(lost about 5 kgs recently) -an reasonably active as I work in the garden and walk a lot.
Should I be worried about getting a heart attack/ what treatment should I be looking at?? Thank you for your time.
