WebTwo options may be preferred in this setting: 1) repositioning of the ventricular lead; in this patient the lead was positioned at the level of the septum without visible dislodgement on chest X-ray; 2) finding a programming compromise; it is possible to change the right ventricular sense vector and to program an integrated bipolar ventricular … WebA pacemaker with AOO setting stimulates in the atrium but has no sensing and thus no response to sensing. Such a pacemaker stimulates with a fixed frequency, regardless of intrinsic cardiac activity. This is called asynchronous pacing because it is not synchronized with intrinsic cardiac activity.

WebSummary Far-field R-wave sensing (FFRS) is a potential complication of dual-chamber pacing, favored by a short post- ventricular atrial blanking and a high atrial sensitivity. FFRS occurrence, FFRS time and FFRS thresholds were systematically assessed in 36 patients implanted with Actros D and Actros DR pacemakers. WebSep 20, 2005 · The purpose of this study is to evaluate the effect of individual adjustment of the postventricular atrial blanking period in avoiding inappropriate mode switch of dual chamber pacemakers.
