Which Pvcs Are Dangerous
I have pvcs. They feel different, like there us a linger pause than normal. How, many seconds between each beat is dangerous?
No one number...: You're likely experiencing "compensatory pauses" equal to 2x the duration of a "normal" heartbeat minus the interval between a normal beat and the pvc. Don't worry. No pause is too long unless you get symptoms suggestive of inadequate blood flow like dizziness or lightheadedness during the pauses. That said, frequent pvcs can result in easy fatigue and that can be a good reason to treat. ...Read moreSee 1 more doctor answer
My dr has noted that I have 2 diff type of pvcs one in rv the other is not said. Why and where could it be coming from. Just assured not dangerous.?
Let me explain: The upper chambers in the heart are more "irritable" than the main chambers. In other words, they are more likely to produce prematurebeats (pacs). A few examples: which is more common- a-fib (atrial) or v-fib (ventricular)? Which is more common- svt (atrial) or VT (v-tach) (ventricular)? Both pacs and pvcs are usually benign, so it's really not an issue. Ask your doctor also please. ...Read moreSee 1 more doctor answer
Not usually: We all have pvcs every day. Some people have a lot more. As long as you don't have any symptoms (dizziness, passing out, shortness of breath or chest tightness), you should be fine. If you do have symptoms or you become very concerned about them, have a cardiologist check your heart out. There are some very simple meds that can help. ...Read more
Usually Not: Pvc's are usually not dangerous. Sometimes increased frequency can lead to other heart arrhythmias, but this is less common. If bothersome, sometimes medication can be prescribed, and cutting out caffeine from the diet can be helpful. An ECG through your primary care provider or cardiologist would be appropriate at this time. ...Read moreSee 1 more doctor answer
Ii have pvcs frequent, multifocal and form, couplets, and big ad trig. Are pvcs mote common in lv.Or rv? Is one more dangerous than the othee?
Freq, multifocal PVC: Pvcs mainly originate from the rv outflow tract, but some originate from from the lv outflow tract, mitral and tricuspid valve annulus. A major concern is that pvcs may initiate vt, polymorphic VT and ventricular fibrillation. This risk associated with pvcs is usually limited to patients with significant underlying heart disease or at risk of developing heart disease. Need to see a cardiologist. ...Read moreSee 1 more doctor answer
Multiple foci: Multiform pvcs are premature ventricular contractions originating from different parts of the ventricle. Each point-of-origin will have a unique form on an ekg. This can be dangerous if it causes tachycardia or ventricular fibrillation. If this is you, you should be under the care of a cardiologist. ...Read more
PVCs are common: PVCs (Premature Ventricular Complexes) are common. Many normal people have a few PVCs. In some people they become more frequent. If there is no evidence of organic heart disease, with normal left ventricular function, and no ischemia (that is, no blockage in the coronary arteries), as shown by a normal EchoCG and a Stress test, PVCs are harmless. Anxiety may increase PVCs in some people. ...Read more
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
