Noninvasive Ultrasound Cardiac Pacemaker and Defibrillator

摘要

A device for providing extracorporeal cardiac pacing. The device includes an ultrasound transducer mountable to the external thorax of a patient and an ultrasound generator for transmitting ultrasound pulses to the ultrasound transducer. The heart rate of a patient is monitored by the device. A controller evaluates the heartbeat as compared with threshold criteria for stimulation of the heart and causes the ultrasound generator to deliver ultrasound pulses to the ultrasound transducer at a prescribed intensity, frequency, and pulse duration.
