Question 1

is sinus bradycardia always a sign of an underlying health issue?

Accepted Answer

Absolutely not!: Virtually all seasoned athletes have sinus bradycardia. Many  normal, healthy non-athletes do as well. Virtually everybody has SB at sometime during sleep.

Question 2

is there a  difference between bradycardia and sinus bradycardia?

Accepted Answer

Mechanisms vary: Bradycardia simply means slow heart beat.  Sinus bradycardia refers to a specific cause for the slow heart beat which is sluggishness of the natural pacemaker cells of the heart (referred to as sinus node).   This could be normal in physically fit people or abnormal especially if associated with symptoms of fatigue, shortness of breath or passing out spells.

Question 3

am i at risk with sinus bradycardia of 50 bpm? i'm 40 y old...

Accepted Answer

Symptoms?: Sinus bradycardia is normal in athletes. If no symptoms with it, no worries.

Question 4

what does sinus bradycardia look like on an ecg?

Accepted Answer

See below: Sinus bradycardia is usually defined as a heart beat of less than 60  beats per minute. Iit by itself does not indicate a heart problem.

Question 5

what is sinus bradycardia and ventricular hypertrophy ?

Accepted Answer

Ecg: I presume you are quoting an ecg report. Sinus bradycardia is a normal type heart rate of less than 60 beats per minute. Ventricular hypertrophy is increased voltage coming from left or right ventricle, perhaps due to increased size of the ventricle.

Question 6

what is sinus bradycardia and right bundle branch block?

Accepted Answer

RBBB and SBC: Sinus bradycardia is slow heart rates below 60 BPM without abnormal beats. The best description for bundle branch block is here: http://www.Mayoclinic.Com/health/bundle-branch-block/ds00693.

Question 7

i have sinus bradycardia at rest of 48-60. am i at risk of developing long qt or long qt if i take certain drugs?

Accepted Answer

QT interval is heart: rate dependent. QTc corrects for this to some extent. Many drugs can cause QT prolongation but usually in individuals with a genetic predisposition. Is there a family history of sudden death? Other members with QT prolongation? These would increase your risk. If not, your risk is relatively low like the general population regardless of your minimal bradycardia. Discuss your concerns with your MD.

Question 8

my ecg shows i have sinus bradycardia and incomplete rbbb. is this a problem?

Accepted Answer

NO: both are "benign" arrythmias...

Hope this helps!

Question 9

can you define sinus bradycardia?

Accepted Answer

Yes: A slow heart rate in which the electrical signal for each heartbeat originates from the sinus node (where it's supposed to originate).  Generally, in an adult, this means a heart rate of less than 60.  But keep in mind you can have a heart rate less than 60 and still be okay.  For example many good athletes, whose hearts are in great shape, have resting heart rates less than 60.

Question 10

what are the most common effects of sinus bradycardia?

Accepted Answer

Usually nothing: Sinus bradycardia is usually a normal rhythm that occurs during sleep or in a highly conditioned athlete. As long as the rhythm is originating from the sinus node, the individual is usually asymptomatic. Slow heart rates associated with abnormal rhythms (such as third degree heart block) may not be tolerated and may be dangerous. Sinus bradycardia can also be a sign of other non-cardiac problems.
