Changes in the phases of left ventricular contraction during induction of general anaesthesia
Anaesthesia, Resuscitation, and Intensive Therapy
|April 1, 1975
Abstract:
By means of polycardiographic tracings the authors assessed the effects of althesin, ketamine and fentanyl on the dynamics of left ventricular contraction when these agents were applied for induction of anaesthesia. A depressing action of althesin was found while fentanyl and ketamine were without effect on the dynamics of left ventricular contraction. Polycardiographic tracings are a useful method for the assessment of the action of pharmacological agents on the cardiovascular system during operations.
