Hi Everyone. I had my yearly checkup today and found out I had an attack of ventricular trachycardia two weeks ago. Other than that, everything was good. I felt the attack and thought it was a couple of missed heartbeats but, apparently, it was a 9 second attack with my heart beating at 230 beats per minute. The cardiologist on call at the clinic prescribed a 5mg beta blocker and I am seeing my regular cardiologist tomorrow to, I suspect, begin a series of tests to find out what happened (or is happening). Right now, I am feeling a little lightheaded but as I am really upset with this news, it could be anxiety. My questions: could this just be a one-off - anyone else had this? and, as I understand beta blockers are for tachycardia and my dual pacemaker (July 2016) is for type 2 heart block and is set at 60 beats per minutes. My resting heart rate is usually around 65 BPM and my blood pressure is around 120/70. Sounds like a contradiction to me -pacemaker for low heart rate and beta blocker for high rate. Any comments?
