[The electrocardiogram of high frequency in the evaluation of hypertensive cardiopathy].
The High-Frequency ECG was studied in 78 patients with systemic arterial hypertension and in 10 normal subjects. The study has shown: a) the P wave is altered initially, according to the disturbances in the myocardial complicance; b) the signs of LVH are mainly: delayed in the appearance of the intrinsecoid deflection, abnormal left direction of vector 3, left electrical systole diminished and counter clockwise rotation; c) the exhaustion fase is represented by increased of the electrical systole, delay in the duration of the intrinsecoid deflection and by primary disturbances of repolarization. The relationships between the ECG and the hymodynamic and metabolic disturbances, are discussed.
