premature ventricular depolarizations
"I just started the Metroprolol for premature ventricular depolarizations. I was on one 25 mg pill a day and it wasn't touching it. I recently was upgraded to two 25 mg pills a day, we will see how it goes. My symptoms include rapid heartbeat while at rest and what feels like skipped beats or double beats. Most of the time they are on the aggressive side. I'm a 32 year old male."
