Temporary pacing is occasionally required during percutaneous coronary artery interventions. This can be accomplished by the insertion of a temporary transvenous pacemaker wire into the right ventricle, but there is some risk and inconvenience associated with this approach. Temporary pacing using the coronary artery guidewire was described in 1985 but is used infrequently. Using currently available equipment, we evaluated guidewire pacing in 26 patients. Guidewire pacing was successful in all patients, but not with all coronary guidewires at acceptable ventricular capture thresholds. No complications occurred from guidewire pacing. Bench testing of multiple different wires showed several with very high resistances likely unsuitable for clinical use. Temporary guidewire pacing is easily performed and should be considered as an alternative to the separate placement of a temporary transvenous pacemaker.
经皮冠状动脉介入治疗期间偶尔需要临时起搏。这可以通过将临时经静脉起搏导线插入右心室来完成，但这种方法存在一些风险和不便。1985年就描述了使用冠状动脉导丝进行临时起搏，但很少使用。我们使用现有的设备对26例患者进行了导丝起搏评估。所有患者的导丝起搏均成功，但并非所有冠状动脉导丝在可接受的心室夺获阈值下都能成功。导丝起搏未发生并发症。对多种不同导丝的台架测试显示，有几种导丝电阻非常高，可能不适合临床使用。临时导丝起搏操作简便，应被视为临时经静脉起搏器单独放置的替代方法。
