For the past year I’ve had heart palpitations on and off, this is anything to worry about?

Hi there,
My name is (—). For the past while, probably a year I’ve had heart palpitations on and off, It feels like a beat is skipped in my chest and gives me a fright. Some days never and one day recently at least once every hour. I suffer with anxiety on and off, have had counseling, hypnotherapy etc which I’m continuing with. But I’ve read that anxiety can give palpitations? But when I get one I get very anxious so quite a vicious cycle. I have a massive fear of death, I also don’t like being apart from my fiancé, so working 3 weeks away at a time, having a train, a small plane and a helicopter for a commute to work doesn’t help things. These palpitations can come when.at rest, lying down, sitting, or during exercise (I’ve noticed more recently). I’ve also read exercise can cause palpitations. I was just wondering if this is anything to worry about or is it due to my anxiety? I’m not going to collapse due to a heart attack from them?

Any help very much appreciated
