I am diagnosed with anxiety and panic disorders. I am having panic attacks and my heart rate gets elevated. My resting heart rate is 100- 115 all the time. I feel pressure and discomfort at my heart area. I cannot sleep at night as there is always unknown fear like feeling. I have to take alprax 0.25 tab. Then also sometimes I cannot fall asleep. I had done ECG 2 times in month of june and both the time it was normal. Doctor gave me inderal 10 mg which has helped bring my HR normal. But after stopping I feel my heart thumping and Heart rate elevates to 100-115. Need some opinions.
