I am a 30 year old female. I've been diagnosed with anxiety. It causes my heart to race at times and I get PVCs and PACs from time to time. These PVCs and PACs take my breath away and I can feel a spike in blood pressure. I take a few slow deep breaths and I feel better. I understand these are benign.
I am worried about my heart rate staying too high, above 100 BPM, for an extended time (hours to days). Would a heart rate above 100 BPM (tachycardia) for hours cause any problems like heart failure or damage my heart? I have had an EKG and echocardiogram. Both have come back normal.
