I am a 24 year old female, 5'8, 195 lbs (obese). I have always had occasional PVCs all my life, went to the cardiologist and said I was perfectly fine. Last year I was doing a workout and noticed skipped beats. My skipped beats would always go away with exercise, now they are frequent during any exertion. I went back to the cardiologist, they did a stress test which showed occasional PVCs with increased HR, he was not concerned at all. So I just went on with my life. Ever since then they have become progressively worse, every time my HR gets above 100 BPM they have become frequent (30 a minute). Went back to the cardiologist, he did an echo which showed normal heart function with PVCs. I went on a beta blocker because I just couldn't take it anymore, I take atenolol 25 mg a day and I hate it. I already have low BP and it makes me dizzy and lightheaded. My doctor just doesn't seem concerned at all. What happened? Why is my heart acting like this all of a sudden? My doctor thinks its because I am out of shape and told me to exercise more but even with the beta blocker, if my HR gets high I still get them. Can the echo not show if something else is going on? Sudden cardiac death does not run in my family, but I am scared that it might with me. I have become so depressed and convinced that I am going to die soon. My doctor just wants to blame all of this on deconditioning and anxiety, but there are people a lot bigger than me and out of shape that don't get these. He thinks my PVCs are adrenaline based. I use to be very active when I was younger, and never felt skipped beats, only at rest. I have seen 2 cardiologists about this and neither of them are concerned whatsoever. I am so tired of this, I don't know what is causing them to get worse over the last year. My heart is apparently healthy and my doctors haven't suggesting getting labs done on my electrolytes. If anyone has any advice or suggestions on what is going on please let me know. I cry everyday thinking I am going To die, I cannot live like this anymore.
