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.
Electrocardiography
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 without 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.
- Q waves may suggest prior myocardial infarction, but in the absence of a clinical history of previous myocardial infarction or CAD,
- Q waves may also be caused by other conditions, including hypertrophic cardiomyopathy, left ventricular hypertrophy, dilated non ischemic cardiomyopathy and accessory conduction pathways.
- Isolated Q waves in lead III or QS pattern in V1 and V2 are nonspecific for diagnosis.
- The occurrence of ST segment depression and T wave inversion in the resting ECG, and signs of left ventricular hypertrophy, left bundle branch block (LBBB) and left anterior hemiblock LAH are compatible with, and favors to, but are not specifically indicative of CAD.
- 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.
- ST segment changes in angina can be seen as downsloping, upsloping or horizontal ST segment depression.
