Patient replied :
Duration: constant for an hour
no risk factors
my thyroid has been checked 100% fine
all but one EKG/ECHO has came back normal
I had my ablation one year ago. June 2, 2014
blood pressure is normal heart rate is at 110 (resting)
present medications: beta blockers
Your resting heart rate is high
I would suggest Holter Monitoring
To do Stress test to rule out the cause of angina
Step up the dosage of beta blockers
Till you do these above test, mean while I suggest tab nitroglycerine in case you have angina.
