Spatial voltages in the assessment of left ventricular hypertrophy (Frank system).

摘要: Summary The existence of a relationship between surface potentials in the QRS complex on one hand, and left ventricular weight wall thickness other was demonstrated 150 individuals studied by orthogonal electrocardiography (Frank lead system) biplane angiocardiography. Equations for estimation were derived from data that same series. They based two simple spatial voltage criteria together with subject's age weight. It shown provide rather reliable means detecting conditions overload. With cut-off point corresponding to 5% false positive rate, had negative rate only 33 % Moreover, minority these subjects hypertrophy terms heart as fraction body
