The predictors of pacing capture threshold (PCT) exacerbation after leadless pacemaker implantation remain unknown. We analyzed the predictors of poor PCT by identifying risk factors using multivariate logistic regression analysis for 211 patients with leadless pacemaker implantation. Twenty patients met the criteria for elevated PCT levels and were categorized in the poor PCT group. Multivariate analyses revealed that PCT (P < 0.0001) and pacing impedance (P = 0.03) were independent predictors of PCT exacerbation. Elevated PCT levels and low pacing impedance during leadless pacemaker implantation were potential risk factors for the replacement of leadless pacemakers after the procedure.
在植入无导线起搏器后起搏捕获阈值 (PCT) 恶化的预测因素尚不清楚。我们通过对 211 例植入无导线起搏器的患者进行多变量逻辑回归分析，确定了危险因素，从而分析了不良 PCT 的预测因素。20 例患者符合 PCT 水平升高的标准，被归入不良 PCT 组。多变量分析显示，PCT（P<0.0001）和起搏阻抗（P=0.03）是 PCT 恶化的独立预测因素。在植入无导线起搏器期间，PCT 水平升高和起搏阻抗低是该手术后更换无导线起搏器的潜在危险因素。
