I am 24 years old, with frequent pvc's every day. I take toprol for them and it helped for about 3 weeks, but they are back, and I have even tried upping my dosage. Well, this has happened a couple times before, but last night I had them really bad, 3 pvc's in a row...2 in a row, single pvc's, it was just going crazy. I FINALLY got to sleep, and was awaken by what felt like what I have read about tachycardia. It was like 8 or more pvc's in a row, but really fast. It's like I try and open my eyes, but I can't, and I can feel myself trying really hard to kick my husband because I am scared and want him to wake up, but... I CAN'T!!! This scares the **** out of me! But as soon as I wake up, it goes away. And... my heart goes right back to beating regular. or at least what i call regular. You know... with all the extra beats.
