I had long qt as part of statin rebound; in fact, the weird pulse -including tachycardia - scared me
half out of my wits especially since I had never had anything like that before. The ER docs said I had long qt and ventricular fibrillation plus RBBB and bradycardia, none of which I had before my year on Simvastatin. Also, severe nocturnal leg cramps and a severe ramping-ing up of the peripheral neuropathy which hit years ago with a year on Pravachol, but it was the heart stuff that spooked me.
