The rsR' pattern in left surface leads in ventricular aneurysm
British Heart Journal
|July 1, 1970
Insights
A specific electrocardiogram pattern (rsR
Area of Science:
- Cardiology
- Medical Diagnostics
- Electrophysiology
Background:
- Coronary heart disease (CHD) can lead to significant cardiac structural changes.
- Electrocardiography (ECG) is a crucial tool for diagnosing cardiac conditions.
- Ventricular aneurysms are serious complications of myocardial infarction.
Purpose of the Study:
- To describe a characteristic electrocardiographic pattern in patients with coronary heart disease.
- To investigate the association between this ECG pattern and ventricular aneurysm.
- To explore the clinical significance and diagnostic value of the observed ECG findings.
Main Methods:
- Analysis of electrocardiographic (ECG) recordings from 18 patients with coronary heart disease.
- Detailed examination of ECG leads, including surface leads, apex lead, and orthogonal X lead.
- Correlation of ECG findings with clinical data and necropsy results in a subset of patients.
Main Results:
- An rsR' pattern, or its variants (rSr', rSR'), was identified in the left surface leads.
- This pattern was observed in 18 patients with coronary heart disease, 17 of whom had ventricular aneurysm.
- Necropsy confirmed ventricular aneurysm secondary to extensive scarring in the anterior and antero-lateral left ventricle.
Conclusions:
- The rsR' pattern and its variants may serve as an indicator of ventricular aneurysm in coronary heart disease.
- Understanding the genesis of this ECG pattern can aid in diagnosing cardiac complications.
- The study suggests potential clinical value for this specific electrocardiographic finding in patient management.
Abstract:
A characteristic rsR' pattern or its variants (rSr' or rSR') with normal or prolonged QRS duration in left surface leads including the apex lead and the orthogonal scalar X lead was described in 18 patients with coronary heart disease; in 17 of them a ventricular aneurysm was present. Necropsy in 12 patients showed the ventricular aneurysm to be secondary to an extensive confluent scarring of the anterior and antero-lateral portions of the left ventricle. Explanation of the genesis of the electrocardiographic pattern was attempted and its clinical value was suggested.
