In the years 1979 to 1985 (period I) 717 (102 per annum), in 1986 to 1989 (period II) 295 (73 per annum) pacemaker procedures had been performed at the cardiothoracic surgery division of Würzburg University. Indications for pacemaker therapy were in 35.4% vs. 36.6% (period I vs. period II) an atrioventricular block grade II or III, in 18.1% vs. 26.4% sick sinus syndrome, in 15.3% vs. 18.0% bradycardic rhythm disturbances, in 9.5% vs. 6.1% a sinuatrial block, in 6.5% vs. 2.4% a bradycardic sinus rhythm, in 12.4% vs. 3.7% others. While 41% of the procedures were performed under general anesthesia during the first period of observation, local anesthesia was predominant later on. Preferred venous access (79% vs. 74%) was the right cephalic vein followed by the subclavian vein (12% vs. 14%). The amount of the two chamber systems rose form 11% (period I) to 24% (period II). Intraoperative complications occurred in 2.5% vs. 5.8% and postoperative (within 14 days) complications occurred in 4% vs. 5.8%, respectively. No death was to be registered. The reasons for the increase of intra- and postoperative complications are discussed.
