Resting heart rate of 90-100, pulse feels slightly uneven & skips occasionally. should i worry? have been told i have pvcs & murmur years ago.

Cardiologist: A cardiologist would be best to advise you about the pvc's and heart murmur. A 24 hour holter monitor would give information about whether the pvc's are benign appearing and only occur singly rather than in couplets or runs which often need treatment. In the meantime avoid alcohol, caffeine, and nicotine. Has your thyroid status been checked?

PVCs: You need an ekg and holter. If you have pvcs >10% of total heart rate in 24 hours then you will be at risk for developing tachycardia induced heart failure. Underlying causes of pvcs should be identified and treated. You need full physical exam, and workup. Consult your physician to get electrolyte check up, ekg, holter and echo.
