Some background: I am a 35 yr. old female. 3 years ago I was diagnosed as having had a silent heart attack. The only symptom I had was palpitations, which I mentioned to my Internist during a routine exam. An ekg showed abnormal results, and an echo showed a small area of damage. I subsequently had a thallium stress test and a heart catheterization, which showed the damage from a "moderate" heart attack, although I had normal coronary arteries. My EF is 50%. None of my doctors could give me any reason for the MI, and they couldn't tell me when it happened. I do not smoke, do not take drugs, drink very rarely and am otherwise healthy, although I could stand to lose 30 lbs.
I recently wore a 24-hour holter monitor to evaluate my frequent palpitations. My internist told me that the monitor showed that PVCs occurred 1% of the time over the 24 hours - she said this was ok. However, she said that there was 1 occurrance of 3 PVCs in a row during the 24 hrs. She said that this was somewhat concerning, and that she recommended I start taking beta blockers. She didn't seem too concerned, but I read somewhere that 3 or more PVCs in a row was called V-tach, and that this is a very dangerous rhythm, possibly leading to sudden cardiac death. Should I be very concerned about this? Do I really need to take beta blockers?
What are the chances that this could be a life-threatening condition? I have an appt. with an electrophysiologist next week, and I am very worried about this.
Thank you in advance for any info you can give me.
