line,
thanks for the post.
We classify bradycardia as heart rates under 60. This is a descriptive term, not a pathologic (abnormal) term for this phenomenon. Unless the slow heart rate leads to symptoms or comes form an abnormal heart rhythm it has little meaning other than to describe the slow heart rate.
good luck

Muy husband always says he does not know what I would do if I did not worry about something, I guess he is right.
Thanks again, Line
So, could bradycardia eventually prevent the heart from reacting normally to increased exertion?
I am inclined to believe it's nothing and that the position itself is the instigator and not the exertion itself.
I'm not really sure if it has so much to do with our positioning or if it's the way we are breathing that is aggitating our ventricles. Not to mention, if you're listening or feeling for your palpitations it is likely that you have unconciously slowed your breathing down, and actually induced more palpitations. I've notice myself doing that also, for the longest time I wasn't even paying attention to that.
As far as resting heart rates go, mine can range from the low 50's - around 61 or so and my doctor expressed concern for that before she knew I worked out consistently. During the summer I used to run 3 miles in the evening around a speed of a mile every 6 - 7 minutes, so I think my heart rate definitely got kicked down from that.
I still worry that I'll have sudden cardiac death though, but I force myself to work-out since I feel like I'm just being paranoid. I've never fainted, or had any other symptoms aside from my palpitations, so I probably should just be glad of that. I go for an echocardiogram on Tuesday, I'll try and post my results here when I get a chance.
Just the opposite of you, my resting heart rate tends to be a little high. Around 90-100 sitting and it goes up when I am standing, usually between 120-140. The 90 always made me feel better but I recently read somewhere that the range for tachycardia was lowered to 90 LOL I never noticed the fast rate until it was pointed out at the doctor's. I work for a museum and frequently stand for long periods of time. I get light-headed and sometimes my mind blanks out, but, like you I haven't fainted either.
You are right about the breathing affecting the ectopics. I had a stress test two summers ago and the rhythm remained normal, but the heart rate would not go down below 135 or so during the recovery period, so they told me to breathe more deeply and when I did the monitor went kablooey and they doctor and nurse said "Whoa" LOL.
I'm not afraid of dying, though I used to hope I wouldn't keel over and faint in front of my peers and embarass myself LOL
There's really nothing else I can figure to do when I feel a quivering beat than to just continue working out. Nothing bad ever happens.
Haven't had the Holter for ectopics, but my past ekg's show tachycardia and otherwise normal.
