Abstract

Over a five-year period, hemodynamic exercise capacity studies and a randomized controlled trial have been performed in a total of 50 patients. DVI vs. VVI pacing showed an increase in stroke work index (P less than 0.005) and a fall in left ventricular filling pressure (P less than 0.05) in 17 patients. VDD/DDD pacing vs. VVI showed an exercise capacity benefit in 44 patients (P less than 0.01) including 8 patients with sinus node disease and a lower peak heart rate (P less than 0.02). Maintenance of benefit was also shown of VDD/DDD pacing in the longer term (13 months) vs. acute (P - NS). The controlled trial VDD/DDD vs. VVI showed benefit in shortness of breath (P less than 0.01) and general well being (P less than 0.01). It is concluded that atrial synchronous ventricular pacing (VDD/DDD) is the mode of choice in suitable patients.

摘要

在五年期间，共对50名患者进行了血流动力学运动能力研究和一项随机对照试验。在17名患者中，DVI起搏与VVI起搏相比，每搏作功指数增加（P<0.005），左心室充盈压下降（P<0.05）。VDD/DDD起搏与VVI起搏相比，44名患者的运动能力得到改善（P<0.01），其中包括8名窦房结疾病患者，且峰值心率较低（P<0.02）。与急性情况相比，长期（13个月）的VDD/DDD起搏也显示出益处（P-无显著性差异）。VDD/DDD与VVI的对照试验显示，在呼吸急促（P<0.01）和总体健康状况（P<0.01）方面有改善。结论是，心房同步心室起搏（VDD/DDD）是适合患者的首选起搏模式。
