Overview

A resting 12-lead ECG is performed and recorded in all patients with suspected angina pectoris. However, a normal resting ECG does not exclude the diagnosis of ischemia. Abnormalites commonly observed on resting ECG include: ST-segment changes, left ventricular hypertrophy (LVH), left branch bundle blockage (LBBB), signs of coronary artery disease (CAD) such as previous myocardial infarction (MI) or abnormal repolarization patterns [1]. An ECG recorded during pain helps to identify an underlying vasospasm.

Indication

As a testing modality, electrocardiography (ECG) is critical not only to add support to the clinical suspicion of CAD but also to provide prognostic information based on the pattern and magnitude of the abnormalities.

Diagnostic criteria

  • In approximately half of all patients with chronic stable angina withou a history of previous myocardial infarction, ECG values may be within normal range. In others, a variety of ECG findings may be present and be suggestive of an ischemic heart disease.
  • A physician should consider these abnormal ECG findings as indications for further evaluation.
  • Giant T-wave inversion in precordial leads can be an important indicator of severe Left Anterior Descending (LAD) artery stenosis.

ACC / AHA Guidelines- Resting ECG (DO NOT EDIT) [2]

Class I

1. Rest ECG in patients without an obvious noncardiac cause of chest pain. (Level of Evidence: B)

2. Rest ECG during an episode of chest pain. (Level of Evidence: B)

ESC Guidelines- Resting ECG for Initial diagnostic assessment of angina (DO NOT EDIT) [3]

Class I (in all patients)

1. Resting ECG while pain free. (Level of Evidence: C)

2. Resting ECG during episode of angina. (Level of Evidence: B)

ESC Guidelines- Resting ECG for Routine reassessment in patients with chronic stable angina (DO NOT EDIT) [3]

Class IIb

1. Routine periodic ECG in the absence of clinical change. (Level of Evidence: C)
