Biventricular hypertrophy ECG and clinical characteristics

Biventricular hypertrophy ECG and clinical characteristics

Biventricular hypertrophy Simultaneous hypertrophy of the left and right ventricle is rather common. The  ECG  has low sensitivity with respect to detecting biventricular hypertrophy. This is because the strong and oppositely directed forces tend to cancel each other out. However, the  ECG  may show features characteristic of biventricular hypertrophy. Biventricular hypertrophy ECG In case the ECG or other examinations suggest  left ventricular hypertrophy (LVH) , one should suspect concomitant  right ventricular hypertrophy (RVH)  if the following ECG criteria are presented: Right axis deviation  (>90°) – This never occurs in LVH. Deep S-wave in V5 or V6 (>6 mm) Large RS complexes in multiple leads P pulmonale Figure 1. ECG changes seen in  left ventricular hypertrophy (LVH)  and  right ventricular hypertrophy (RVH) . The  electrical vector  of the left ventricle is enhanced in LVH, which results in large R-waves in left sided leads (V5, V6, aVL and I) and deep S-waves in right sided  chest leads  (V1,…
