Sorin Device Troubleshooting Questions : The following EGMs are from a routine Sorin dual chamber pacemaker interrogation. Both EGMs were stored as “V Bursts”. What is your analysis? The patient has complete heart block. Sensing, threshold, and impedance measurements were all stable. AP 3%, VP >99% Answer: The first recorded episode contains NSVT with appropriate… Continue reading Sorin Device Troubleshooting

PMT Questions : What is happening in this EGM? Answer: This is an example of a PMT episode that is successfully terminated with the algorithm AP on PMT (Abbott). The PMT detection rate is 120bpm. The device detected eight consecutive VP-AS intervals with a rate higher than the PMT detection rate (appx. 120), the device… Continue reading PMT
