Abstract:
Objective: The paper inquires into a new external temporary cardiac pacing method. Method: The research uses a microcomputer-based multi-functional external temporary cardiac-pacing device made by the authors for sending pacing signals. The pacing mode and pacing rate of the device can be adjustable. The pacing pulse width and pacing current of the device can also be adjustable. It inserts a syringe necdle-like negative pacing pole into the chest muscle in the prior-cardiac area of a male adult mongrel dog; it pastes a positive pacing pole on the back area near heart of the dog. It takes intravenous injection isoptin 5mg into the male mongrel dog. After 5 minutes, the heartbeat of the dog suddenly stops; it does pacing experiment for the dog at this time and observes the results of the pacing experiment. Results: After temporary cardiac pacing, the heartbeat of the dog returns, pacing ECG of the dog appears, the pacing for the dog is active. Conclusions: It is a new and benefit external temporary cardiac pacing method.
