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 bradyarrhythmia's such as AV block.
Electrocardiogram
Resting EKG
The heart rate is < 60 beats per minute. 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.
24 Hour Ambulatory Electrocardiogram Monitoring
The diagnosis is usually made with the help of a 24-hour ambulatory electrocardiogram (ECG) or telemetry.
