title: [Costs, benefits and hazards of electrophysiologic studies in sinoatrial and atrioventricular block].
abstract: Time and costs involved in electrophysiologic study for sino-atrial and/or atrio-ventricular blocks were evaluated in 42 patients. Analysis of charge for staff, specific electrophysiologic equipment and disposable items reveals an operating cost of 540.000 lire per study. An electrophysiologic study is the only method of diagnosing with certainty the level of A-V block and of assessing the prognosis of patients with infranodal conduction disease. It also allows a careful choice of permanent pacing mode. The potential risk, although small involved in this procedure, its cost and the need of a high operating standard suggest however that the number of electrophysiology laboratories should not indiscriminately increase.
