Hemiblocks are partial and occur within one or more fascicles of the atrioventricular bundle branch. Clinically, the most common types are the AV nodal and infra-Hisian blocks. Web3 dec. 2016 · Hemiblocks may simulate or conceal the ECG findings of myocardial infarction or ischemia and mask or simulate ventricular hypertrophy [5]. This ECG also looks like right ventricular hypertrophy at one look of V1 and V2. Tall R in aVL may appear like left ventricular hypertrophy. References
