I had them occcasionally too but then they got more frequent. I went to a cardiologist who recommended a stress test/echocardiogram, etc., and I found out that I have hypertrophic cardiomyopathy which is a thickening of the heart muscle. I am 61 yrs. old. Young people who have it are in greater danger than older people, so please go to a doctor and get it checked out. Let me know how you make out.
