title: A simple new method for atrial triggered pacemaker. Preliminary clinical trials.
abstract: Inadequacy of cardiac output in the ventricular paced complete heart block is generally related to lack of rate adaptation to varying atrial contribution. The status of the art in leads technology had not yet freed the clinicians from the necessity to use a double lead system (atrial and ventricular) in order to maintain the atrial synchronization. Authors present a new simple catheter with double electrode (atrial receptor and ventricular stimulator) which, connecting to a new conceived VAT generator, let to obtain atrial synchronization with a single catheter-electrode implantation. External units were tried in 22 patients who needed temporary treatment. The results appear to be positive in all cases and encourage the Authors to continue with the task undertaken until the system is made implantable.
