Pacemaker crosstalk

WebCrosstalk can only occur in dual chamber or biventricular pacemaker. It happens less often in more recent models of dual chamber pacemakers due to the addition of a ventricular … WebThis signal level is sufficient to lead to a ventricular sensing event. In a second phase of the study, the incidence of cross-talk at high pacing rates was studied in patients with implantable dual chamber bipolar pacemakers. In 166 clinical trials on 106 patients with the same pacemaker, there was evidence of cross-talk in 1/59 cases at 110 ...

Prevention of Crosstalk in Dual Chamber Pacemakers

WebPrevious studies have demonstrated that core clock genes are rhythmically expressed in peripheral tissues, including the liver, skeletal muscle, pancreatic islets, and white and brown adipose tissues. These peripheral clocks are entrained by physiological cues, thereby aligning the circadian pacemaker to tissue functions. WebOversensing may also occur when electrical events in one chamber is sensed by the lead in the other chamber, resulting in inappropriate inhibition of the pacemaker in the latter chamber. This type of oversensing is referred to as pacemaker crosstalk. Oversensing may also occur when the ventricular lead interprets the T-wave as an R-wave. WebCROSS TALK in dual chamber pacing it is possible that the atrial pacemaker spike will be sensed by the ventricular wire and is misinterpreted as a ventricular depolarisation -> … hot tub or ice bath after gym
