Due to damage during ablation/flutter/av node reentry/6 ablations total, I have now had my av node ablated due to pacemaker syndrome/av dissociation/dyssynchrony/tachycardia history plus 3rd degree heart block. I am 45 female and very active, working out intensely 3x a week with walking 2 other days, struggling with hypotension and lightheadedness during exertion. During a stress test my blood pressure dropped to 68/40 almost fainting due to several skipped beats in a row, still having av dyssynchrony. Ended up working the biotronik to the max, am now at the lowest setting possible for PVARP at 175, AV delay 100. The problem is the P wave was hitting outside the PVARP. There is definite delay in sensing atrial activity from the onset of the P wave so that is why the AV delay was shortened so that the overall PVARP was shortened. Now I have PVCs. My question is are there any risks to developing Pacemaker Mediated Tachycardia, I have read that due to the short PVARP this can be an issue. I am pacemaker dependent with no escape rhythm. I have struggled with getting the settings write for almost 2 years. I now doctor at Mayo clinic so I have the best trying to get it fixed as I have been with them this past year. I am unique as I do not have heart disease, my problems began from a car accident and the electrical part of my heart was damaged including the nerve that controlled it so I an unique to mayo and a great study. I am somewhat of a guinea pig but hope that someday I can help others with the same issue. Anyone know of other risks with these type of settings? I am ventricular paced with a dual chamber pacemaker. My ejection fraction will be checked in December to see if I will need a third lead or not.
