Force ballistocardiograms from an ultra-low frequency system were recorded on four healthy young volunteers during thiopental-ether anesthesia, thiopental narcosis, and other related states. During stage III, plane iii thiopental-ether anesthesia, the contractile force of the heart decreased to approximately one-third the control value. Collateral evidence suggests that ether was the cause of myocardial depression. Author
