[Changes in ventricle dynamic data in geriatric patients during spinal anesthesia. Results of a polymechanocardiographic study].
Systolic time intervals were performed in 14 elderly patients after spinal anaesthesia. The following parameters were measured or calculated: Heart rate (HR), total electromechanical systole (QS2), pre ejection period (PEP), isometric contraction time (ICT), left ventricular ejection time (LVET), 1/PEP2, PEP/LVET and pdiast/RS1. There was a significant increase of the relation of the pre ejection period to left ventricular ejection time (PEP/LVET), while there were lower values for 1/PEP2 and pdiast/RS1 ratio. The data suggest that compensatory cardiac activity following spinal anaesthesia in geriatric patients is remarkable diminished in contrast to young people.
