Stimulants cause slow heart rate.

I've noticed that when using stimulants (atleast with racemic amphetamine and 4-FA) my heart rate slows down considerably, especially on relatively high doses (more than 120mg of either one). A while ago, on 160mg of 4-FA (which caused a terrible headache), my heartrate slowed down below 50bpm, I normally have a heart rate of about 75bpm. After some dancing and jumping around I can (just) manage to stay above 60bpm but as soon as I sit down my heart rate slows down to about 45. When this happens it usually scares the shit out of me and there's a little voice in my head telling me to stop dosing if I want to survive, and because this little voice is usually right about most things I always stop when my heart rate drops below 60. Is this purely reflex bradycardia caused by high blood pressure or is there another mechanism that causes this? And also how dangerous is this? I do suspect I have undiagnosed ADD and I'm aware that stimulants have a calming effect on people with ADD but I always assumed this is mainly a psychological effect and not a physical one. Because nowadays I only use amps once or twice a year I have no tolerance whatsoever.
 
I think that could be it, but what worries me is that it not only beats very slow but also not very strong and I wonder why I don't hear about this more often??? I like to dose reasonably high but I guess I'm not the only one who does this. I read somewhere that the constant vasoconstriction caused by amphetamine abuse causes the veins to lose their flexibility over time and stay constricted even when amphetamine use is ceased. Having been quite a heavy abuser in my younger days (I'm in my 30s now), I wonder if this could have had a lasting effect (apart from my bad teeth),that'scausing this altough I highly doubt it.
 
The obvious answer is that you should stop using stimulants if you value your health and possibly your life.

It looks like slow pulse caused by vasoconstriction to me as well. Give your heart a rest once in a while... or preferably most of the time.
 
What is your blood pressure on them? Paradoxical effects of stimulants on pulse and BP are not unheard of.
 
My first reaction to this is that you ought to consult a doctor immediately and get a proper test performed. You won't get arrested, and you might even meet your life expectancy. From the way you worded this:

I always stop when my heart rate drops below 60.

...it sounds like you aren't likely to take the best advice given to you in this thread, which is

No high is worth premature death, my friend.

As you said, this sounds like reflex bradycardia. I get this off of 5 hour energies. Maybe get your heart examined, but I doubt it's anything to worry about, unless you get lightheaded. The fact that you can dance and jump around probably means that your heart is getting the blood where it needs to be.

4-FA also leaves my heartrate very low compared to other stimulants, <80 bpm at even 360 mg of 4-FA, compared to >100 with higher d-amphetamine doses. 4-FA is also a very relaxing drug, I think.

As for how *weak* your heartrate is, how are you measuring it? Consider that how strong your heartbeat feels might also be related to blood pressure.
