A Premature Ventricular Contraction seems to be fairly easy to observe. It is physical. One can even observe them by taking a pulse. When hooked up to an EKG or monitor it appears to be possible to speculate the location based on the image it leaves on the recording device (sometimes referred to as the morphology). Doctors often classify the PVCs according to how many PVCs are observed versus normal beats ( often expressed in term of percentage of PVCs vs normal beats, or ectopic burden). PVCs in succession or combination are also noted, as would be any evidence of other abnormal beats.

Doctors also look to see if pVC activity coincides with time of day. Sometimes PVCs are more common during periods of stress of exertion, seeming to suggest a Adrenalin like trigger.

So even if the problem is anxiety, it’s still a problem to be looked into.
