[Study of patients admitted to a telemetry unit]

The current situation of the telemetry unit of Vigil de Quiñones Hospital was studied. Telemetry indications, results, and problems observed since the unit was inaugurated were studied to determine the usefulness of telemetric heart rate monitoring and centralized surveillance in an intensive care unit (ICU) in detecting severe arrhythmias, controlling antiarrhythmic treatment, and evaluating why and to what extent telemetry is clinically useful. In our center, telemetry is used to monitor patients with well-established needs. In most cases, arrhythmias are monitored, most frequently premature ventricular complexes, sinus bradycardia and supraventricular tachycardia. Telemetry was useful in arrhythmia treatment and the follow-up of patients with temporary or permanent pacemakers. In a significant percentage of patients (8.62%), telemetry was the key to their ICU admission and, possibly, their survival. There were generally few problems with signal transmission.
