- CMR: Cardiovascular magnetic resonance. ECG: Electrocardiography. PPV: Positive predictive value. NPV: Negative predictive value. LAE: Left atrial enlargement. RAE: Right atrial enlargement. P mitrale: Notched P wave with interpeak duration > 0.04s. NPTF-V1 > 0.04s·mm: Area of negative P terminal force in lead V1 > 0.04s·mm. PPTF-aVL: Positive P terminal force in lead aVL. Inferior P waves: P wave in any of the leads II, III, or aVF.
