Temporary pacemaker undersensing
WebResults: The strongest predictors of postimplant effusion by univariate analysis were the concomitant use of a temporary transvenous pacemaker (hazard ratio [HR] 3.2, 95% confidence interval [CI] 1.6-6.2, P = .001) or steroid use within 7 days prior to implant (HR 4.1, 95% CI 1.1-10, P = .003). Weaker predictors were use of helical screw ventricular leads, … Web12 Feb 2024 · Under-sensing by a temporary pacemaker after cardiac surgery and ventricular fibrillation Under-sensing by a temporary pacemaker after cardiac surgery and …

Web3 Nov 2024 · assess underlying rhythm -> turn pacemaker rate down and assess native rhythm (do not turn down the output energy – there may be no underlying rhythm!) determine sensitivity (minimum current that the pacemaker is able to sense) -> place in VVI, AAI or DDD, increase sensitivity until the sense indicator stops flashing Web1 Jul 2015 · Undersensing: pacemaker paces asynchronously in spite of the presence of obvious P waves. Oversensing: failure to pace in spite of obvious bradycardia. Cross-talk: failure of DDD pacing; atrial pacing spike …
WebTemporary epicardial pacing is very effective for bradycardia or low output syndrome after CPB but there are instances in which a PVC’s R wave may be undersensed despite an ap- propriately low sensing threshold. This undersensing can cause the R-on-T phenomenon, which may induce critical arrhythmia. Web1 Oct 2016 · Undersensing occurs when the pacemaker fails to detect spontaneous myocardial depolarization, which results in asynchronous pacing. Atrial or ventricular …
