Understand your predicament. Sinus rhythm is the name given to the normal rhythm of the heart where electrical stimuli are initiated in the SA node, and are then conducted through the AV node to the ventricles. Heart block is an abnormal heart rhythm where the heart beats too slowly (bradycardia). There are three degrees of AV blocks. First degree block is the prolongation of PR interval. In first degree heart block there is a split-second delay in the time that it takes electrical pulses to move through the AV node. First degree heart block rarely causes noticeable symptoms.
So, based on your symptoms your doctor may plan therapy. Discuss this with your doctor when you meet him.
