I have had symptoms of a resting heart rate of 99-140, chest and back pain - sharp and squeezing pressure, pressure in my chest, back and left arm, migraines, dizziness, fainting, large dips in blood pressure, nausea, sweating,
and shortness of breath. I am on disopyramide 300 mg per day
and still symptomatic. I had 3 echos done and 3 xrays to confirm.
