Table 2.

Possible abnormalities on 12-lead electrocardiogram and echocardiography in patients with cardiac sarcoidosis

Twelve-lead electrocardiogram	Echocardiogram
AVB, any degree	LV dysfunction (EF < 50%)
Fragmented or prolonged QRS complex	LV wall thickening or thinning
Complete bundle branch block	Local akinesia or dyskinesia
Abnormal Q-waves	LV aneurysm
T-wave inversions	Reduced global LV longitudinal strain
Frequent premature ventricular beats or NSVT	RV enlargement and reduced RV free wall strain
Epsilon-wave	Pericardial effusion

AVB indicates atrioventricular block; EF, ejection fraction; LV, left ventricular; NSVT, non-sustained ventricular tachycardia; RV, right ventricular. The contents of the table have been compiled from several sources.^2,37–41
