描述了一种使用双极或多极导管常规记录人体希氏束(H)活动的技术。记录导管通过Seldinger方法经皮插入右股静脉，并在透视下进入右心房。在9名患者中，将预先形成的曲线放置在穿过三尖瓣的导管尖端，可以在连续的心脏周期中稳定地记录到希氏束活动。右房起搏导致P-H间期随频率增加而逐渐延长，但H-S波间期在所有频率下均保持不变。当对颈动脉窦施加压力时，在心房起搏时也会产生类似的P-H间期延长。在人类中使用这种记录技术将有助于对心电图的诊断解释，并可用于人类房室和室内传导的各种研究。
A technique for the routine recording of His bundle (H) activity in man using a bipolar or multipolar catheter is described. The recording catheter is inserted percutaneously, via the Seldinger method, into the right femoral vein and advanced fluoroscopically into the right atrium. Placement of the pre-formed curve at the catheter tip across the tricuspid valve in nine patients resulted in stable recordings of His bundle activity in successive cardiac cycles. Right atrial pacing resulted in progressive lengthening of the P-H interval with increasing frequency but the H to S-wave interval remained constant at all rates. Similar lengthening of the P-H interval was produced during atrial pacing when pressure was applied to the carotid sinus. The use of this recording technique in man will facilitate diagnostic interpretation of the electrocardiogram and can be used in various investigations of atrioventricular and intraventricular conduction in man.
