I had a very hard pounding heart beat, so hard I actually thought I might be having a heart attatck at points. I thought my heart was going to blow through my chest. But that was from a very high dosage of Clen. ..

Yep, it happens to me. I'll be lying there and all of a sudden I feel my heart beat extra hard like one time and then I have shortness of breath for like 1 second, sometimes I also feel something in my throat when that happens.

Micro

i get it too. when i lie down, i feel it beating or racing. then when i flip over, it starts to really pound.

Had it, talked to a doctor friend and was told it was one of 2 things (his opinion without an ekg)

1. a natural murmur
2. high bp due to aas

I stopped thinking about it and it went away.... really, no shit.

did a ekg and holter monitoring...all was normal...did an echo of my heart, completely normal thank god but still this condition is scary as hell...literally can feel my heart at certain times of the day vibrating my whole chest especially at night before bed...usually accompanied by shortness of breath....bp was high 140/90 hypertension.... thanks for the responses guys...
