I am 27 years old and was diagnosed with MVP three years ago after
fainting from an irregular
heartbeatHeart palpitations
Ultrasound, normal fetus - heartbeat
Ultrasound, ventricular septal defect - heartbeat. I was placed on 25 mg/day of the beta blocker
atenololAtenolol
Atenolol-chlorthalidone, which stopped the
fainting, but I still had the occasional irregular
heartbeatsHeart palpitations
Ultrasound, normal fetus - heartbeat
Ultrasound, ventricular septal defect - heartbeat (about one noticeable episode per day).
Two days ago, I began noticing the irregular beats (manifesting themselves as a short
flutterAtrial fibrillation/flutter in the chest then a "BOOM" beat) were occurring every 10 minutes on average. Could the atenolol be losing its effectiveness and should I up the dosage to 50 mg? Could the MVP have suddenly gotten worse like it did?
While writing this, I've had two irregular beat episodes. I've read all the literature about these flutters being harmless, but for them to pick up in frequency that dramatically is startling and, by all indications, not common.
Basically, I need some advice as to what I should do.
