A new method is described for measuring the unipolar left ventricular cavitary electrogram by means of a standard pigtail ventriculography catheter. Experiences with this technique in 30 patients are described with particular reference to changes in the S-T segment of the cavitary electrogram during cardiac stress by atrial pacing. This method allows convenient recording of His bundle potentials from the left ventricular outflow tract in most patients.
本文描述了一种通过标准猪尾心室造影导管测量单极左心室腔内心电图的新方法。介绍了30例患者使用该技术的经验，特别提及了心房起搏引起心脏应激时腔内心电图ST段的变化。该方法能在大多数患者中方便地记录左心室流出道的希氏束电位。
