I have been having heart palpitations and higher than normal heart rate for two 1/2 months. I had a normal EKG w my PCP, but went in for an echocardiogram to be on the safe side. This was normal also. After ending up in the ER w palpitations, light headedness and tingly feelings in hands it was determined from the heart monitor that I was experiencing PVC's. A holter monitor was ordered to verify. The results came back showing that I am experiencing PVC's and that they are benign. The thing that has me worried is that my average heart rate was 97! I don't remember it being terribly high during the time I was wearing the monitor. Do PVC's cause the heart rate to appear higher than it actually is? I didn't don any strenuous exercise during while I had the monitor either. Only a moderate 2 1/2 mile walk with my dogs.
