A dual-chamber pacemaker for confirming pacemaker mediated tachycardia (PMT) after initial detection. The minimum V-V pacing interval is extended to be slightly longer than the interval of the sensed atrial rate. If the A-V Delay intervals in successive cycles remain constant, as opposed to progressively...http://www.google.com.tw/patents/US5423868?utm_source=gb-gplus-share專利 US5423868 - Dual chamber pacemaker which detects, confirms and terminates pacemaker mediated tachycardia
