I am awakened every night, sometimes 4-5 times per night with a quivering in my chest. I have worn an event monitor for 2 weeks and recorded 19 events. My doctor told me the results were normal. I had an echo cardiogram which was also normal. I have bradycardia and have taken my pulse between 47 and 53 bpm when at rest. I am 53 years old and while not overweight, am not athletic. My doctor is treating me for anxiety at this point,

prescribing 75mg effexor daily at present.
