<s>[INST] I have been diagnosed with multiple PVC s in a row (bigeminy). This just started 2 months ago out of the blue, but a had had problems with my heart rhythm before and take metropolol tartate twice a day. This is an awful feeling and it is hard to catch my breath. It never lets up, I sleep less than normal and feel really tired and worn out. [/INST] Hello and thanks for writing. I can understand your concern and would try to help you in the best possible way. PVC's are quite common problem that affect a number of people. An important thing to rule out in such cases is the presence of any structural heart disease. This can be done by simple 2D echocardiography. In some cases stress echo or other stress test may be required to further delineate the problem. If there is no underlying structural disease, and you have no prior history of heart attack, sudden cardiac arrest, no family history of premature cardiac problems tenth you are not at any undue risk, You PVC's in such case is probably benign and does not require any further treatment. If however your symptoms are too frequent to wonder your day-to-day activities then you may consult a cardiologist and discuss with him the possibility of undergoing a radio frequency ablation, which is a permanent cure for this condition. I also suggest you to get your Blood pressure checked up frequently as long-standing uncontrolled BP is a cause for PVC's and proper control of BP leads to resolution of PVC's. </s>
