目的在心脏再同步化治疗(CRT)中应用左室四极与双极导线进行对比研究。方法选取符合CRT适应证的患者16例植入左室四极导线为观察组,25例植入双极导线为对照组,观察有关数据并进行比较。结果两组患者均成功植入CRT。观察组手术时间较对照组显著减少[(106.8±25.6)min vs(125.3±25.7)min,P<0.05]。随访6个月观察组左室起搏阈值较对照组显著性降低[(1.20±0.48)V vs(1.91±1.14)V,P<0.05]。对照组出现1例膈神经刺激。观察组术后3个月时QRS波时限更短[(152.7±15.8)ms vs(167.3±15.3)ms,P<0.05]。结论左室四极较双极导线可显著简化手术流程、缩短手术时间,并改善左室电极起搏阈值。
Objective To compare left ventricular quadrupole and bipolar lead in cardiac resynchronization therapy (CRT). Methods Sixteen patients with CRT indications were enrolled in this study. Left ventricular quadrupole wires were implanted in the observation group. Bipolar leads were implanted in 25 cases as control group. The data were observed and compared. Results Both groups of patients were successfully implanted with CRT. The operation time in observation group was significantly lower than that in control group [(106.8 ± 25.6) min vs (125.3 ± 25.7) min, P <0.05]. The left ventricular pacing threshold in the observation group was significantly lower than that in the control group at 6 months of follow-up [(1.20 ± 0.48) V vs (1.91 ± 1.14) V, P <0.05]. One case of phrenic nerve stimulation occurred in the control group. The observation group had shorter QRS duration at 3 months postoperatively (152.7 ± 15.8 ms vs 167.3 ± 15.3 ms, P 0.05). Conclusion The left ventricular quadrupole bipolar lead can significantly simplify the surgical procedure, shorten the operation time and improve left ventricular electrode pacing threshold.
