When is bradycardia dangerous? I'm not in good shape but have a low BPM
Hello I am 22 years old and I have a couple of problems.
First off I am really out shape due to being a couch potato for over year,
not having a job... etc.
I have been having panic attacks for which I take a low dose of betablocker (1,25mg of Nobiten).
The betablocker works great against panic attacks because it blocks the adrenalin.
When I wasn't taking a beta blocker yet, I could sometimes measure a heartrate of around 57bpm when I was laying down.
Since I'm taking this beta-blocker I can measure a heartrate of around 52bpm when laying down.
I figure that when I'm sleeping, my heartrate must definately drop below 50bpm.
A low heartrate can be a sign of physical fitness,
but trust me I'm not ;) I am kind of skinny though, even though I eat a lot.
I guess I must have a quick metabolism.
When exactly is bradycardia (a heartrate below 50bpm) dangerous?
I have asked my GP and cardiologist about this but they were not concerned.
I would like to hear some more opinions though.
If you don't have any problems like dizziness or fainting I'd say there is nothing wrong with your low HR. I think Bradycardia is defined as a (sustained?) HR below 50. Even that is not necessarily a problem, if it occurs when you are asleep, you and not physically active, and don't need the oxygen.
Some people have strong (large) cardiovascular systems, and low HR. These people are likely in a good position to excel as an athlete, especially long distance runner. But some, you it seems, are not. I used to run, and wish I had a higher capacity cardio, e.g., low rest HR.
I think the main concern about low HR is a heart stop, arrest. If you doctor thinks that is a concern consideration of a pacemaker would be in order.
Again, from what you say, and what I know, I think you should be just fine.
Even though the doctor said low heartrates on Betablocker would not be a problem for me,
I had to stop using them because even in very low doses they would make my heart beat very slow.
Sometimes during the day i felt like i was going to faint and the last day that i took it ended up giving me a very uncomfortable night.
The drug was pushing my heart to a very low HR (49) but i saw my heart kept trying to climb to a higher HR. I did not sleep much that night because my heart felt really weird.
