I don't see how Tren could cause direct EKG changes. Shortness of breath is and has always been a side effect of Tren use. It's been know to degrade endurance ever since people started using it. PVC's and PAC's are caused by irritable foci in the heart typically caused by stress, dehydration, stimulants, etc.... ST elevation is indicative of an MI (myocardial infarction) or heart attack. Aside from MI's, broad spectrum ST elevation can be pericarditis.
I think people are just looking for things to blame Tren on. I could spend all day giving lectures about MI's, pericarditis, endocarditis, ischemia, etc, but that's not what everyone wants to hear.
Ok, one thing is for certain. Tren causes anxiety. Anxiety leads to an elevated heart rate. If the heart rate becomes too elevated them of course it will lead to ischemia bc the heart is starving for oxygen, which is why it is beating so fast. If the heart starts to beat too fast the yes, you will see a different morphology in the P-QRS-T complex bc the heart is trying to compensate for the stress that you're putting on the heart.... BUT once the heart rate returns back to normal, the morphology will return to normal bc homeostasis is back to normal.
Make sense?
Sorry man, I love cardiology and I could seriously spend ALL day discussing it bc its just a love of mine. It's difficult to explain to people that have no idea about the heart, but ill do my best to knock it down to your level. I don't mean any disrespect by saying "your level", but hopefully you get what I'm saying.
Bottom line is I bet you're okay and have nothing to worry about. Feel free to keep asking questions or PM me if you'd like.
