Cardiodynamic and electrocardiographic alterations induced by blood sampling in normal and hypertensive donors.
The 12 routine electrocardiographic leads, apical phonocardiogram, piezocarotidogram, Korotkov blood pressure, sitting and standing, were recorded before and after 500 cc blood sampling in 20 hypertensive donors and 20 normals. The cardiodynamic (systolic time intervals) disturbances in hypertensive donors were more frequent and more persistent than those observed in the normotensive group, despite the favourable effect of the blood sampling on the blood pressure values. The most significant cardiodynamic alteration was the increase in the pre-ejection period/left ventricular ejection time--indicating a more reduced ejection fraction in the hypertensive group and pointing out that the improvement of left ventricular work by decreasing the blood pressure after blood sampling is less important than the hypoxic effect of blood loss.
