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.

2018 ACC/AHA/HRS Guideline on the Evaluation and Management of Patients With Bradycardia and Cardiac Conduction Delay[1]

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)

Recommendations for Exercise Electrocardiographic Testing in Patients With Documented or Suspected Bradycardia or Conduction Disorders

Class IIa
1.In patients with suspected chronotropic incompetence, exercise electrocardiographic testing is reasonable to ascertain the diagnosis and provide information on prognosis. (Level of Evidence: B-NR)
2. In patients with exercise-related symptoms suspicious for bradycardia or conduction disorders, or in patients with 2:1 atrioventricular block of unknown level, exercise electrocardiographic testing is reasonable (Level of Evidence: C-LD)

Recommendation for Ambulatory Electrocardiography in Patients With Documented or Suspected Bradycardia or Conduction Disorders

Class I
1.In the evaluation of patients with documented or suspected bradycardia or conduction disorders, cardiac rhythm monitoring is useful to establish correlation between heart rate or conduction abnormalities with symptoms, with the specific type of cardiac monitor chosen based on the frequency and nature of symptoms, as well as patient preferences. (Level of Evidence: B-NR)

Electrocardiogram

Resting EKG

Electrocardiogram obtained upon admission showing sinus bradycardia at 42 beats per minute. Case courtesy by Amartya Kundu and Timothy P. Fitzgibbons"Acute symptomatic sinus bradycardia in a woman treated with pulse dose steroids for multiple sclerosis: a case report".
