S in V 1 or V 2 ≥30 mm; R in V 5 or V 6 ≥30 mm; 3 ST-T Abnormalities: ST-T vector opposite to QRS without digitalis; ST-T vector opposite to QRS with digitalis; 3 1 Negative terminal P mode in V 1 1 mm in depth and 0.04 sec in duration (indicates left atrial enlargement) 3 Left axis deviation (QRS of −30° or more) 2 QRS duration ≥0.09 ...
A holosystolic murmur heard at the apex or axilla can indicate mitral regurgitation, which can be found in patients with HCM. Other physical exam findings that may be present are a jugular venous pulse with a prominent A wave, an S4 heart sound, and split second heart sounds with severe disease and prominent outflow tract obstruction.

In 2015 cardiomyopathy and myocarditis affected 2.5 million people. [6] Hypertrophic cardiomyopathy affects about 1 in 500 people while dilated cardiomyopathy affects 1 in 2,500. [3] [10] They resulted in 354,000 deaths up from 294,000 in 1990. [7] [11] Arrhythmogenic right ventricular dysplasia is more common in young people. [2]
Nonetheless, the ECG is used to assist with the diagnosis of RVH. A post mortem study on 51 adult male patients concluded that anatomical RVH may be diagnosed using one or more of the following ECG criteria: [8] Right axis deviation of more than (or equal to) 110° (see hexaxial reference figure) R-wave dominant over S-wave in V1 or V2
