Overview

An ECG may be helpful in the diagnosis of bradycardia. An upright P wave in leads I, II, and aVL, and a negative P wave in lead aVR, indicates a sinus origin of the bradycardia. It is vital to exclude other causes of bradyarrhythmias such as AV block.

Electrocardiogram

Resting EKG

The heart rate is < 60 beats per minute.

• 

24 Hour Ambulatory Electrocardiogram Monitoring

The diagnosis is usually made with the help of a 24-hour ambulatory electrocardiogram (ECG) or telemetry.
