[Complications due to endocardial and epimyocardial electrodes in 171 patients with artificial pacemakers].

On the basis of experience with 171 patients the advantages and disadvantages of a sutureless, corkscrew-like myocardial electrode are compared with those of endocardial electrodes. Electrode complications were significantly less frequent in patients with sutureless myocardial electrodes and never lead to death. However, a benign postpericardiotomy syndrome was frequent (16% of cases). Electrode dislocation was the main complication in patients with endocardial electrodes.

Reciprocal beats initiated by artificial pacemaker.

In conclusion, the underlying mechanism for this rhythm disturbance in our patient is the re-entry phenomenon, which is dependent upon a localized unidirectional block in the A-V junction. The predisposing factors, including digoxin and Inderal which tend to prolong A-V conduction, are considered for the mechanism of the production of the reciprocal beats in our case. Upon temporary withdrawal of digoxin and Inderal, the re-entry phenomenon has disappeared.
