Hello And thanks for reading.. Firstly I am 21 male 6ft tall 178 lbs etc I had an EKG In FEB that showed things ot be OK other then an elevated rate.. which the doctor did and still does consider anxiety... on the 17th something (I assume my parents talking about the ER to me due to pain ) triggered an attack I had a heart rate of probably 160-180 and it took 4 1/2- 5 hours to get back below 100 .. this happend again on the 26th at which point my xanax dose was put to 3 mg a day.. ( I am seeing a very skilled GP but I need a new psychitrist so she is helping me ).. But I went in and explained this to her and she wants me to try lexapro 10 mg a day so I am and a Blocker.. Metoprolol. sorry if I spelt it wrong.. but I was curious if anyone could explain to me how low the heart rates can go I mean i've hit 54 ( this is my first dosage aswell) .. and the blood pressure with the added xanax and such ( I can take up to 4mg a day but I rarely go past 2.5mg) and only 2 mg so far today.. I have had readings of heart rate around 57 or slightly lower 54.. I am on Top. as 25mg in the morning with breakfast 1 hour after I take xanax.. I would really appreicate any help sorry for the spelling to. very drained. I took it at 7 am and at 7:27 pm my bp is 127/71 and pulse 59. And this is not the extended release.. and this is my first tiem taking the drug so please give me some advice

User avatar Hello SirWence - To answer your main question, one's heart rate normally should be between 60 - 100. That, however, is an arbitrary range and what is normal for one person is not for another. Then with use of beta blockers the rate will often be considerably slower. As a rule doctors like to see it stay above 50, but in reality, if there is no problem with the heart's electrical conduction system it can get down into the 40's (although if it does one ought to check in with the doctor just to be sure nothing new has developed). As a rule people on an effective dose of metaprolol will, at rest, have a rate somewhere between 50 and 70. During exercise it can get considerably higher, and when very relaxed or falling asleep it can fall below 50. So you seem to be squarely in the "normal" range for someone using a beta blocker. Of course the Xanax can actually have a slight additive effect and possibly make things a tiny bit slower.

Anxiety (and the attendant release of adrenaline) can really get one's sinus heart rate higher than you might expect. This is the real underlying problem that needs to be managed - panic attacks and GAD, as I'm sure I don't need to tell you, can be incapacitating and really disrupt one's life. Good luck with that and as far as the heart rate and meds you are right on the money.

Best of luck to you.
