Actions Elicited by In-hospital Follow-up of Cardiac Devices

This study will enroll all patients who will attend an in-hospital follow-up of cardiac device since February 22nd 2010 to June 21st 2010. Primary objective of the study is to observe how many of patients seen during these period (approximately 5000) will receive a change in cardiac device programming or in drug therapy or a scheduled or urgent hospital admission. These data should help to clarify how useful and safe is a remote monitoring strategy for this kind of patients.
