Wow, my post was munged in the last paragraph really bad. That was supposed to be two paragraphs. I think I know what happened, I had a "less than sign" in there, I think medhelp filters that out because it may think it's HTML code. buggers. I'll try to piece together what I said

Infrequent is a moving target. The numbers I see thrown around are between LESS THAN 6,000 per day to LESS THAN 20,000 per day depending on who you talk to.
There was a study done on frequent ventricular ectopy, greater than 15,000 per day if I recall correctly, that showed it can cause reversible left ventricular dysfunction (I'm not sure if this was enlargement OR hypertrophy or hypotrophy). I forget the exact details. Anyways, the study showed that people who had their ectopic beats fixed reversed the issue. This would indicate that a high load of ventricular ectopy can cause muscle issues with the heart (eventually) which can be reversed if treated.
For me, saying "in structurally normal hearts are all arrhythmias benign in nature" isn't absolutely true.
All the findings have to be evaluated together.
I think it's safer to say that in structurally normal hearts, isolated AND infrequent PVCs are benign.
Isolated means random single events.
Bigeminy isn't isolated to me.
Runs, NSVT, or VT aren't isolated

good evening, I've just been reading various posts on this forum tonight. I think u mentioned about structurally normal hearts and arrhythmias. Just to make sure im understanding correctly, in structurally normal hearts are all arrhythmias benign in nature. i had an echo last month and it was thankfully normal, I get very frequent pvcs, mostly in bigeminy (14, 000 pvcs daily). My cadio doesnt seemed worried at all, but i still am and im going to start bugging him to send me to an EP doc. Im always wondering when or if its time to head to the ER, my cardio said if i had a fast rate sustained for approx an hr, but that seems somewhat wrong to wait that long if one is in v-tach-unless im misunderstanding
No one can predict the future. I'm aware of one study that shows for certain types of benign ectopics there is no correlation to future illnesses. I've seen one other study that contradicts this. So who knows....
I always tell the story on here of my grandmother who had frequent palps and was always in the ER from what I can remember. She eventually did die. She was 96 and died from complications of dementia. Her heart was the last organ to fail.
