Ummm you might want to go to a cardiologist i think its called to figure out what exactly is wrong with your heart. I am not a doctor but i took beta blocks for a few days and if your heart is like going 140+ and or you have some structural issue with your heart it wont fix it.
The one thing I've never understood about safe heart rate when resting (not exercising) on stimulants (also regardless of what a person's blood pressure is for the sake of argument, which of course also factors into the equation), is whether or not a person's heart rate at the moment considered safe or unsafe based on the number alone or whether or not the person is exercising (while NOT on stimulants), or maybe even scared of something that might speed up the heart, or whether or not a person is simply at rest and on stimulants??
Like, my normal resting heart rate when not on stimulants (other than some coffee), is usually around 72bpm, or before coffee it has been in the upper 50s, which is generally ok, but I have heard that during intense exercise it is not unsafe for one's heart rate to go up to 2 and a half times their normal HR, maybe even 3 times it, so is that not unsafe because you are exercising and exercise is healthy while stimulants are not, or is not unsafe because one's heart rate being that high, as long as it is not USUALLY or VERY FREQUENTLY THAT high, is just not HIGH ENOUGH IN GENERAL TO BE DANGEROUS???
Like, if I'm running really hard at the gym I've seen my heart rate go to the upper 100s, like maybe 160 or whatever, and I've heard that that is safe, so why couldn't it also be safe if one's resting heart rate is 160 while on a stimulant SO LONG AS YOU AREN'T DOING THEM THAT OFTEN???
I mean, I have just decided to quit Dexadrine and stimulants stronger than coffee entirely, and I have not taken my BPM or blood pressure while on them and think it is possible they might get to unsafe levels (which is just one reason I'm quitting VERY soon....like within the next week FOR SURE), so IF my resting heart rate gets that high (LETS HOPE IT DOESNT...BUT I"M QUITTING SO I HOPE I AM OK GOING FORWARD....) then I'm not a good candidate for a study about this cause I use them too often.
But lets say someone takes a stimulant 1-2 times a week and when they do so their heart rate gets as high as when they exercise but they are at rest, is it really more dangerous considering that the number is the same??
Or do you also have to factor in WHY the person's heart rate is that high and also perhaps how long the person's heart rate is that high, cause people don't exercise for like 4-12 hours straight keeping their heart rate and BP up like they meet be on stimulants for that duration of time?
I don't know, I mean OBVIOUSLY stimulants are really bad for you and exercise is really good for you, and in general also the more you exercise the lower your heart rate and BP will be when at rest which is good (I HAVE to exercise more), but it is possible to bring one's heart rate and blood pressure up to unsafe levels through sober exercise alone as well, and then when someone refers to your "resting heart rate", TO ME at least, it kind of seems like if you are on a stimulant that is messing with your HR that that isn't REALLY your "resting heart rate" it is your heart rate while not exercising but reacting to something that is altering it, so I would not think that one's HR (and BP) TEMPORARILY going up to levels that are not unsafe while exercising (like 140 or whatever)....would necessarily be SUPER dangerous all the time if at rest but on a stimulant. It's a question of if a number is unsafe because the number is too high regardless of what you are doing or not. I mean, isn't dangerous HR and BP based mostly just on what the number is and how frequently it gets that high??
Maybe not...
I know I gotta quit stimulants for sure though.
I do know that BEFORE I was prescribed them about 8 years ago I had an Echo Cardiogram, Endo Cardiogram and Nuclear Stress test and all said my heart was healthy so I have hope that it still is, but I'm not going to mess with it anymore regardless.
