S/p ablation for vtach/45%pvc's, TSH now zero despite tapazole (methimazole) (no sx), cardio says I must take nadolol to prevent complications-do I need nadolol?
May need more: If your cardio says so then yes. You may need more if your TSH is persistently zero. ...Read more
Is it normal for pvcs to last as long as 30 min? Most of mine come when i lie down and usually in sets of 3's. Should i be concerned?
Not normal: It's common for people to feel pvcs more when they lie down. But if you have long periods of every 3rd beat being premature (trigeminy), you should be evaluated. The test of choice is a 24 hour holter exam in which you wear a monitor for 1 day. Commonly the evaluation also includes an echo, stress test, chest xray, and blood work for electrolytes, thyroid, magnesium and renal function. ...Read more

They come from the ventricles of the heart.sometimes it is an isolated problem and sometimes it comes with some other heart diseases. They may also be triggered by external factors such as drugs medications etc. ...Read moreSee 1 more doctor answer
Possible, not likely: If the PVC comes at just exactly the right time (or really at the wrong time), it can cause v-tach. It's called the r on t phenomenon. If the ventricular electrical impulse occurs during the recovery phase of the preceding beat, ventricular tachycardia can occur. ...Read moreSee 1 more doctor answer
Need more info: Many people get occasional PVCs. If the heart is structurally normal & healthy, these extra beats are not necessarily concerning, but we assess the risk of a sustained tachycardia (e.g., those ventricular beats happening in a series) which could be dangerous. How many PVCs, the number of origin sites & the tendency to happen in a row (e.g., with couplets, triplets or runs) may help determine risk. ...Read more
