A new implantation technique in the upper lateral part of the right atrium has reduced the complication rate of atrial electrodes to less than 4% at 11 months' follow-up. P-wave amplitude and acute and chronic threshold are in the order of conventional ventricular electrodes. In 10 of 56 patients with atrial-triggered ventricular pacemakers the cardiac output at rest and during exercise was found to be respectively 8% and 17% higher than with fixed-rate ventricular pacing. This hemodynamic benefit is longlasting, in contrast to findings with non-atrial synchronized pacing.
一种新的右心房上外侧植入技术在11个月的随访中已将心房电极的并发症发生率降低至4%以下。P波振幅以及急性和慢性阈值与传统心室电极相当。在56例心房触发心室起搏器患者中，有10例患者静息和运动时的心输出量分别比固定频率心室起搏时高8%和17%。与非心房同步起搏的结果相反，这种血流动力学益处是持久的。
