It’s possible, but very unlikely. If I’m monitoring my (admittedly very ill patients) I don’t think much of isolated PVCs until I start to get more than 5-10 per minute. Even then, they aren’t much to get excited about until they get strung together, are associated with hemodynamic issues, or start increasing (ie, my patient has 2-3/minute and a couple hours later 10/minute).
I would treat them as a general sign of cardiac irritability, but if you’re having a hard time catching them on your watch they’re not frequent enough to be terribly concerning unless you’re feeling symptoms with them like dizziness/lightheadedness.
Yep, a PVC is one type of ectopic beat. I would treat it as a general marker of cardiac irritability, but unless you’re having them frequently (and by frequently I’d say like 5-10 per minute), it isn’t a concern.
Generally doctors won’t intervene unless symptomatic (dizziness, lightheadedness, chest pain (not just feeling the beats, but *pain*, shortness of breath, etc) until around 10% of your beats are PVCs.
