Then the healthcare provider must determine whether the bradycardia is likely to be persistent or due to a transient (temporary) cause, such as an infection. The sinoatrial or sinus node is in the upper chamber on the right side of the heart, which is the right atrium. Since the native rhythm is currently normal, the pacemaker isn't triggered, and instead sits back and senses the rhythm. Most people experience ectopic rhythm on occasion. However, a significant number of patients who have had atrial fibrillation also have premature beats. Show Less.
