Clinical InvestigationsTemporary Transvenous Pacemaker Therapy: An Analysis of Complications
Section snippets
METHOD AND MATERIAL
The charts of 113 patients requiring the insertion of 142 temporary tranvenous demand endocardial pacemakers from Aug 1, 1967, to Jan 1, 1972, were reviewed. On 61 occasions, pacemakers were introduced through a cutdown in a brachial vein, and on 81 occasions a femoral vein approach was utilized with a modification of the Seldinger technique using a Teflon inner catheter and a dilating sheath (Percutaneous Catheter Introducer, USCI).
All were inserted in the cardiac catheterization laboratory
DISCUSSION
The safety and morbidity of the methods of temporary pacing have not yet been accurately defined, despite their widespread use throughout the world. The most likely reasons are the apparent simplicity of the techniques, predisposing to a cursory assumption of safety and resulting in a paucity of data concerning risk and incidence of complications.10
A careful assessment of the complications reported in our population indicates that ventricular arrhythmias constitute the most common complication
