title: The electrocardiogram in morbid obesity.
abstract: Electrocardiographic variables that occurred with significantly higher frequency in morbidly obese patients than in lean controls were low QRS voltage, leftward shift of the P, QRS, and T axes and multiple electrocardiographic criteria for left ventricular hypertrophy and left atrial enlargement. P-terminal force, RaVL, SaVR, and R/S ratio in lead V1 values were significantly higher in morbidly obese than in lean subjects.
