The endocardial electrodes were placed in endoventriculus beside bed withoutfluoroscopy in 9 patients who required temporary cardiac pacing and theresults were satisfactory.The manipulatory points are below:operatingcarefully with lightly and softly handling,noticing hand’s feeling,tryingagain by roling the electrode and/or changing its top’s direction whenmeeting with venous valves or branches.Judging the position of electrode’stop according to the right ventricular luminal electrogram.As comparedwith the setting of electrode under X ray,our method is superior in savingtime and requires less instrumente,the patients needn’t be moved,bothphysicans and patients are avoided X radiation’s injury.
