I won't go into my history, but I've been to the ER twice this week. First time, adenosine failed twice to bring down 180+ pulse. Diltiazem given, and worked. Sent home with extended-release 120mg diltiazem. Experienced breakthrough arrhythmias and eventual return to tachycardia 170bpm that lasted 8 hours before heading to the ER again. Given fast-acting diltiazem 60mg, which seems to be working so far, although I'm still experiencing arrhythmias. Cardiologist preliminarily diagnosed AVNRT and recommended ablation asap. But now I, in addition to having this happen again, I am incredibly anxious about whether Medicaid covers this procedure. I can't find ANY information anywhere. Does anyone know? MD said this isn't life-threatening, but I can't understand how having this happen, usually at night, consistently and being unable to convert it through vagal maneuvers, etc could not eventually lead to complications. Anyway...I'm really sorry to go on...I am more fearful and anxious than I'd like to admit, about my heart and about the money it may cost to fix it.
