I am 70 years old and in good shape except for what has been labelled by my GP as having an extra systole. He tells me that it’s a benign condition not requiring any treatment. The thing is that I don’t feel that the condition is all that benign. I can only describe it as feeling like a fish is swimming around in my chest and I get the occasional whack against the ribs with its tail. In other words, I am much more aware of my heart beat than I think I should be. This alone wouldn’t be so bad but it’s not just the physical thumping of the heart that’s the problem. There’s a vague sense of unease and anxiety that never seems to let up and I know that life would be so much nicer without this extra systole and the ensuing constant awareness of my heart beating. Is there any treatment for the condition?
