When you have heart issues you can become heart focused. This is not my opinion but the medical and mental heath guidance for my medical professionals at Mayo Jacksonville.

During the day (again from my experience and what my doctors advised me) you are busy doing things, you are not so heart focused. When you go or try to go to sleep at night you are quiet, laying there and common to become heart focused and feel every PVCs, PACs, tachycardia, discomfort, etc.

How long has it been since your pacemaker was implanted? It takes about a year for body to encapsulate the device and wires. I am on my 3rd ICD/Pacemaker so have gone through this encapsulation time period. And for me like my EP stated it will feel better after encapsulation.

You asked about sleep medications. I am going to advise of what I take and it was described by Mayo Psychiatric medication specialist. It is Trazodone. What trazodone did for me was it stop my mind from racing and concentrating on heart focus. I was able to sleep with it.

But we are all individuals so what worked for me my not work for you. One thing about Trazodone is for me caused very vivid dreams. My specialist told me because it increases serotonin.

Don't accept the way you feel. Reach out to your medical doctors and advise them exactly the way you feel and mentioned things if they would help you.

How do you sleep. On back, sides, etc. The way you sleep affects the organs inside your body. Thus you will feel more heart feelings like on your left side versus you right side. Talk to your doctors about sleeping positions and on your own try the right side, then see if the left side improves or makes worse.

Good Luck!
