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
- An ECG may be helpful in the diagnosis of bradycardia. Findings on an ECG diagnostic of bradycardia include:
- The heart rate is < 60 beats per minute.
- An upright P wave in leads I, II, and aVL.
- A negative P wave in lead aVR, indicates a sinus origin of the bradycardia.[1]
24 Hour Ambulatory Electrocardiogram Monitoring
- The diagnosis is usually made with the help of a 24-hour ambulatory electrocardiogram (ECG) or telemetry.
