I am a 23 year old female and I experience tachycardia from time to time. My recent episode was last night 2-24-11 and I woke up at 2:45 with my heart pounding so fast in my chest that I couldn't even count the beats. I also could tell my blood pressure was elevated because it felt like my heart was about to beat out of my chest. My chest was tight, I was dizzy and I felt so weak I could hardly move around but I couldn't lay still either cause it felt like I was going to die. I have seen a cardiologist who just blew off my symptoms and never gave me a diagnosis but prescribed me with propanolol and to only take one when I'm in the midst of an attack. "If it should happen again, which I doubt it won't." Were his words. I've landed in the ER once because my last attack lasted two hours, this last one lasted about 45 minutes, I took the propanolol about 15 minutes in when the techniques I was taught to "reset" my heart rhythm weren't working.
The last time I had an attack was at the end of last month and I was just getting off my menses. This time, I'm in the heaviest part of my menses. Could it be related to my periods? The cardiologist mentioned I was pretty anemic would that cause a rapid heart rate though? It's like someone turns on a switch and my heart starts going a mile a minute and it only happens when I'm trying to rest or in the middle of deep sleep. I also had a mini-episode on the way back from the cardiologist office it lasted about 15 minutes and I used the bear down technique to make it stop.
Can anyone tell me what's going on with me? Perhaps shed some light as to why all my tests came back normal? I've had ECG and a stress ECG both times they came back normal. It took a while however for my heart rate to come down from 195 during the stress echo. I am overweight, I've been trying to lose the weight from my last pregnancy and I'm not a fitness buff either. That's might explain it, it may not.
These episodes scare me, I think I am having a heart attack every single time because my chest get really tight my heart is pounding out of control, I feel weak and like I could faint any second. I have a two year old I have to raise and take care of so nothing can happen to me. And I know it's not an anxiety attack because I'm under no extraordinary stress. That would cause an onset of anxiety attacks since I am usually sleeping or about to sleep when these attacks happen.
Anyone else experience this?
