Your story sounds like mine. I cannot tolerate the beta blockers or calcium channel blockers. I become short of breath, have peripheral edema and chest pain. None of the drugs control PVS / VTach episodes. Two electrophysiologists did not recommend ablation( stating it was not always successful or the arrhythmia is difficult to induce on the table. I was told I needed a pacer/defibrillator in 2021. I have hypertrophic cardiomyopathy, a “mild” bridge in LAD, mild mitral regurgitation. I have been guessed at with, brugada, POTS, and now disautomia. I have PVCS daily that may or may stop and I go into nonsustained V-tach. My thyroid function is normal, electrolytes normal. I was told possibly sleep apnea( mild) but I now have a cpap device ( with no improvement).
Fatigue, stress, caffeine and alcohol are all culprits to increase episodes. My EF has gone from 77 to 60 since I had AICD implant. I have never been shocked but I am paced at 60. The meds ( which I am not taking any now) would drop my HR to the 40’s. I am sick of having these meds thrown at me with no explanation of why or how to fix the problem. I can have an episode of vtach where I am very close to losing consciousness. I have learned to take deep breaths and pray it subsides. I have had several echos, the mri was not performed due to artifact from AICD. I am now awaiting a cardiac CT but expect no intervention from this either. I am 66 very active and semi-retired. ( I was a RN for 30 yrs). I am disappointed with the direction healthcare is going. You must be your own advocate and find a doctor you trust .
