The pacing Swan-Ganz catheter was evaluated for its ability to monitor atrial and ventricular electrical activity during cardioplegic arrest on cardiopulmonary bypass. This endocardial electrical activity was compared with the activity found on the standard electrocardiogram (ECG). The atrial electrodes detected activity that was noted also by visual inspection. The ventricular electrodes detected recurring electrical activity in 7 of 18 patients. Three of these 7 patients did not have simultaneous standard ECG activity, indicating that, in the usual monitoring circumstances, this ventricular electrical activity would not have been treated with repeat cardioplegia. If the pacing Swan-Ganz catheter is used for clinical care, it can be used also to monitor myocardial electrical activity during cardioplegic arrest.
对起搏型 Swan-Ganz 导管在体外循环心脏停搏期间监测心房和心室电活动的能力进行了评估。将这种心内膜电活动与标准心电图（ECG）上发现的活动进行了比较。心房电极检测到的活动通过肉眼检查也能观察到。心室电极在 18 例患者中的 7 例检测到反复出现的电活动。这 7 例患者中有 3 例在标准 ECG 上没有同时出现活动，这表明在通常的监测情况下，这种心室电活动不会通过重复心脏停搏液治疗。如果将起搏型 Swan-Ganz 导管用于临床护理，它也可用于在心脏停搏期间监测心肌电活动。
