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.

Recommendation for Electrocardiogram (ECG) in Patients With Documented or Suspected Bradycardia or Conduction Disorders
| Class I |
| 1.In patients with suspected bradycardia or conduction disorder, a 12-lead ECG is recommended to document rhythm, rate, and conduction, and to screen for structural heart disease or systemic illness. (Level of Evidence: B-NR) |
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.[2]
24 Hour Ambulatory Electrocardiogram Monitoring
- The diagnosis is usually made with the help of a 24-hour ambulatory electrocardiogram (ECG) or telemetry.
