Radiofrequency ablation has gained acceptance in the treatment of patients with symptomatic Wolff-Parkinson-White syndrome. The purpose of this study was to characterize the relation between temperature and other electroconductive parameters in patients undergoing atrial insertion accessory pathway ablation utilizing a thermistor equipped catheter. The mean temperature and power at sites of atrial insertion ablation are lower than has been previously associated with creation of radiofrequency lesions in the ventricle. While high cavitary blood flow in the atrium may result in cooling, the thinner atrial tissue may require less energy to achieve adequate heating than ventricular myocardium.
射频消融术已被广泛应用于治疗有症状的预激综合征患者。本研究的目的是利用配备热敏电阻的导管，对接受心房旁道消融的患者的温度与其他导电参数之间的关系进行表征。心房旁道消融部位的平均温度和功率低于先前与心室射频消融灶形成相关的水平。虽然心房内较高的腔内心血流可能导致冷却，但较薄的心房组织可能比较心室肌需要更少的能量来实现充分加热。
