[Electrocardiography of the hypertensive patient: correlations with hemodynamic parameters].
A comparative study between electrocardiographic signs of left ventricular hypertrophy and haemodynamic parameters is performed in 184 permanent hypertensive patients. They are divided into 3 groups taking into account the level of electrocardiographic changes. Patients with a normal electrocardiogram have a slight increase in arterial pressure, an increase in cardiac index (P is less than 0.01) and total peripheral resistances (P is less than 0.001) and a reduction of plasma volume (P is less than 0.001). Patients with a moderate change in their electrocardiogram have normal cardiac output, high peripheral resistances (P is less than 0.001) and a slight decrease in plasma volume (P is less than 0.05). Patients with a left major ventricular hypertrophy have a reduced cardiac output (P is less than 0.01), increased peripheral resistances (P is less than 0.001) and a normal plasma volume. The significance of such facts, especially concerning the hemodynamic response in upright position, is discussed.
