Overview
The most important and prevalent ECG findings associated with systemic lupus erythematosus (SLE) include sinus tachycardia, ST segment changes, and ventricular conduction disturbances.
Electrocardiogram
The most important and prevalent ECG findings associated with systemic lupus erythematosus (SLE) include sinus tachycardia, ST segment changes, and ventricular conduction disturbances. SLE can affect cardiaopulmonary system in different ways including pulmonary emboli development, Libman sacks endocarditis, and conduction problems. [1]
Important ECG findings in SLE patients based on prevalance:

- Sinus tachycardia
- Prolong QT
- ST segment changes
- Nonspecific
- Compatible with myocardial infarction
- Left ventricular hypertrophy
- Ventricular conduction disturbances
- Incomplete bundle branch block
- Right bundle branch block
- Left bundle branch block
- Left anterior fascicular block
- Left posterior fascicular block
- Supraventricular arrhythmias
- Premature atrial complexes
- Atrial fibrillation
- Atrial flutter
- Premature ventricular contractions
- Atrioventricular heart block
- Right ventricular hypertrophy
- Right ventricular strain pattern
- T wave inversions in the right precordial leads (V1-4) ± the inferior leads (II, III, aVF). This pattern is associated with high pulmonary artery pressures.
- Right axis deviation
- Dominant R wave in V1
- Shows the manifestation of acute right ventricular dilatation.
- Right atrial enlargement (P pulmonale)
