I`m wondering if anything can be done about extra systoles which I have had on & off since I was about 15. In the last 15 years they have been much more frequent. I had several tests done on my heart about 2 years ago, & was told that I haad high cholesterol, which Iv`e already mentioned, but also that they extra beats are caused by a condition called 1st degree heart block. I was scared when I was told this, but the doctor reassured me that it`s not dangerous & is common in people who are very fit. I don`t have any major trouble with this conditon except that it is a bit uncomfortable & disconcerting to have a heatbeat that feels as if it`s stopped, & then goes thud, & I also get palptations sometimes. The cardiologist who did the tests doesn`t seem concerned, but is there anything that I can do to lessen these symptoms?
