[A new simplified method for implanting temporary epicardial electrodes].

The authors present a new simplified method for implanting temporary epicardial electrodes, which can be carried out extemporaneously during operation from a standard electrode. The modified electrode showed an improvement over the standard electrode in the myocardial thresholds with respect to milliamperage as well as voltage at both atrial and ventricular levels (p less than 0.05 for atrial and P less than 0.005 for ventricular). On the 7th day after placement the modified electrode appears to be more reliable than the standard electrode and demonstrates less degeneration of its threshold and current characteristics (P less than 0.05).
