event recorder interpretaion

[jonesy70]

Have just returned my 7 day event recorder to the cardiologist and am awaiting results.. I was a little bit concerned about what some of the display messages could mean when I pressed the button  eg.- deviated waveform and irregular heart beat came up many times over the 7 days.  Unfortunately I did not experience any of the palpitations that has recently caused me anxiety -  feels like a few missed heart beats followed by intense anxiety (shaking etc) and then a fast heart beat. The fast heart rate (over 100 but not much more) gradually settles down. Do you know what this could possibly be.? I have previously had an ablation which markedly reduced the number of  PVCs I was having.  In recent times my pulse rate also seems higher than normal - up from 70 to 80 despite increase in atenolol.  
In terms of other history, I have stable bicuspid aortic valve  and an ejection fraction of 70 with normal Echo stress tests. All blood test are normal etc  Lionel

Thanks  - wise counsel! Believe it or not, since  returning the event monitor I have had 2 separate tachycardia episodes of short duration - 10-20 seconds (could be SVT?) that started and ended abruptly. This makes me very anxious and scared to exercise.  While I have had just about every cardiology test there is, and depending on the results of my latest event monitor, I think I may ask to see my Cardiologist again for re-assessment/reassurance that there is nothing sinister going on.   cheers mark

I don't have time to really comment on all of the post, but one thing hit me: you said that your heart rate ( just over 100) GRADUALLY settled down. True arrhythmias start and stop on a dime, they don't gradually slow down.
Anxiety is going to play a huge roll in this picture, so keep that in mind.The heart rates in the 70-80's range are not really too high. Some drugs can cause the heart rate to increase some, but this really isn't asn increase that is significant with 60-100 being the normal range. When I took Verapimal my heart rate jumped up to 160+; I had to come off the drug. If it were me, I wouldn't give this a second thought, but I am not you and you are the one to decide whether or not this is impacting your life.
