Right Heart Strain

Tachycardia, S1Q3T3, tall P wave in II, ST elevation in right-sided leads (aVR, V1, III), right axis deviation, new right bundle branch block, new incomplete right bundle branch block, and T wave inversions especially in the inferior and right-sided precordial leads (II, III, aVF, V1, V2, and V3) have all been suggested as right heart strain patterns.
