The complications caused by the implantation of pacemakers have recently deceased, but not all can be avoided yet.
Two cases of runaway phenomena of pacemakers were found during the early stages of tachycardia, and these pacemakers were replaced by new generators successfully.
One of the cases was found by transtelephone monitoring. The transmitter that was developed by us was used which transmits ECG and pacing signals simultaneously by a simple acoustic coupler.
The patient was admitted immediately. After the admission, the pacing rate of the patient had gradually ince ased in a short time.
This fact suggests that it should not be fitted to define runaway phenomenon by pacing rate only.
