I've had this for awhile now, though lately it seems to be getting worse: from time to time I have a "sucking" feeling coming from the area of my heart. That is, my chest feels almost hollow and that it's trying to suck the contents out of my throat.
There's no pain, no tightness, no squeezing. It gets a little worse and last longer (sometimes much longer--over an hour) after exercise, but can come when I'm at rest also. My heart doesn't seem to beat any faster or slower, it just--feels like it's sucking.
The last time I checked for a murmur (about a year ago) there didn't seem to be one present. As far as I know I don't have a heart condition--though my cholesterol was high the last time I had it checked, a couple of years back, and there is some history of heart disease in my family. I get moderate exercise but also drink 100-200 ounces of caffeine per week.
The closest match I've found to symptoms is PVCs, but that doesn't seem to quite fit either. Does anyone else have this problem or have any idea what it might be?
