Implication

Reinforces classic ECG patterns for initial LVH/RVH assessment; leaves open validation against modern imaging in diverse cohorts.

Key Points

The study aims to review electrocardiographic criteria for diagnosing left and right ventricular hypertrophy.
Analysis of electrocardiographic patterns in left and right ventricular hypertrophy.
Comparison of R wave and S wave amplitudes in Lead 1 and Lead 3.
Left ventricular hypertrophy is indicated by a tall R wave in Lead 1 and a deep S wave in Lead 3.
Right ventricular hypertrophy shows a small R wave in Lead 1 and a tall R wave in Lead 3.
