I have dysautonomia. I often have abnormal ECG readings when I m feeling very bad. Today s reading is moderate right and mid precordial disturbance. Negative T in V3 V4 with small negative T in V2 V5. When I feel good ECG is normal. When I am symptomatic often my oxygen will show drastic dropping for 2-3 min as low as 67 then raises to mid to high 80 s as soon as I lay down. It s normal. 97/98 when I feel good. It s rare been trying to get in orphan disease clinic. Drs have trouble treating my symptoms. I am 46 I was 35 when I first got sick. My grandmother had same symptoms and passed at 49 of sudden cardiac death. I am under close care of Drs but the past 2 yrs have become more symptomatic. Array of autonomic dysfunction. POTS. Respitory a fib a flutter recently developed neurological raynauds and Printzmetals. I wonder if the Printzmetals causes the abnormal ECG. And oxygen flux. Oh when oxygen drop hr goes high. Usually 140-160 then drops as oxygen rises. Not sure if fast hr makes oxygen look low or low oxygen makes heart go up but I know something interferes with my berating because I can feel it drop and feels like an elephant on my chest before the reading shows it s dropping I can say it s fixing to drop without seeing reading and I know when it gets back up. If it stays in the 80 s I don t feel the change Sorry for info overload. I know my diagnosis. My question would be thoughts on the ECG? Thoughts on how dangerous is the oxygen flux is? And any treatment ideas? ranexa helps the Printzmetals but I can only tolerate it in 2 week intervals due to kidney pain. Take clonazepam .5 when my heart rate won t slow at bed time but can t take during day and drive so my hr runs around 120-140 most days and I manage to function when it gets higher I have to stay home and take clonazepam Can t take beta blockers because of POTS and my blood pressure already runs low causing me to pass out. I take saline to treat that at home. Again Sorry for info overload. I know my diagnosis. My question would be thoughts on the ECG? Thoughts on how dangerous is the oxygen flux is? And any treatment ideas?
