Sutureless epicardial pacemaker lead: a satisfactory preliminary experience. 1975

S Stewart, and J Cohen, and G Murphy

The first pacemaker systems used the epicardial electrode. The transvenous endocardial electrode rapidly supplanted the epicardial electrode since it could be positioned with less morbidity and mortality and was associated with a lower incidence of wire breakage. The long term complication rate of the transvenous electrode had not been inconsequential. The sutureless epicardial electrode combines the greater reliability of the epicardial lead system with the ease of insertion and low morbidity of the endocardial lead system. We have used this electrode in 33 patients. The electrode was positioned using the subxiphoid approach and local anesthesia in most patients. There have been few complications and none that resulted in long term morbidity. There have been no deaths related either to the operative approach or to the pacing system. There has been no instance of lead failure during the follow-up period.

D010496	Pericardium	A conical fibro-serous sac surrounding the HEART and the roots of the great vessels (AORTA; VENAE CAVAE; PULMONARY ARTERY). Pericardium consists of two sacs: the outer fibrous pericardium and the inner serous pericardium. The latter consists of an outer parietal layer facing the fibrous pericardium, and an inner visceral layer (epicardium) resting next to the heart, and a pericardial cavity between these two layers.

D010984	Platinum	A heavy, soft, whitish metal, resembling tin, with atomic number 78, atomic weight 195.084, symbol Pt. It is used in manufacturing equipment for laboratory and industrial use. It occurs as a black powder (platinum black) and as a spongy substance (spongy platinum) and may have been known in Pliny's time as "alutiae".	Platinum Black

D006327	Heart Block	Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.
