multiple PVCs in a row, or not?
Several times, over the course of a few months, I experienced what I think were PVCs, while I was indoor rock climbing. Today, immediately after coming down off the wall, I experienced what seemed like four PVCs in a row. However, they couldn't have happened faster than 100 bpm, and if I had to guess I'd probably say that they were more like 80 bpm, possibly even slower. Is it possible that it only felt like they happened in succession, and there were, in fact, beats in between the PVCs? The reason I'm concerned about how many occurred in succession is because I've read that more than three is considered Ventricular Tachycardia, which I've further read is cause for concern. Does it have to be beyond a certain speed to be tachycardia, if it's the type of tachycardia that consists of three or more PVCs in a row? I didn't feel dizzy or experience any chest pain when it happened.
I'm seeing a doctor on the 7th, but this is causing me a tremendous amount of anxiety in the mean time.
Also, can restricting calories too much for a prolonged period of time during a weight loss diet lead to bradycardia? If so, how long would it take after resuming normal eating habits for the heart rate to return to normal?
