[The Herz Handy--a new telemedical service concept for heart patients]

Abstract

Telemedicine is a new milestone for the health care system in the care of patients with heart disease. New technologies and the possibilities of fast data transmission have enabled this step forward. The Cardiophone offers a new telemonitoring Service Concept, which is available 24 hours a day. The patient is by the aid of the Cardiophone connected with the Medical Service Center at just the press of a button, can record and transmit an ECG and can be localized by the incorporated GPS. We report about our experiences with 363 patients over 3 years. Out of 5064 patient contacts associated with 7561 calls, 559 emergency contacts occurred. From the initial main complaints, working diagnoses were established. The final confirmed diagnoses were arrhythmias (27.8%), coronary heart disease (25.9%), psychovegetative syndrome (12.7%), backbone pain (6.2%), gastrointestinal syndrome (3.6%), others (1.8%), and exclusion diagnosis (19.9%). Ten myocardial infarctions were diagnosed, of whom 3 were confirmed; the other 7 were treated as stabile angina pectoris. Overall 823 ECG were transmitted, in average 1.6 ECGs per emergency contact. In 131 ECGs changes of the ST-segment or T-wave could be documented; 26 patients showed a pacemaker ECG. Atrial and ventricular arrhythmias as well as conduction disturbances were seen. The majority of emergency contacts (n=477, 85.3%) were successfully managed by the Service Center. In 38 emergency contacts (6.8%) admission to hospital was recommended; in 4 cases (0.7%) an ambulance was activated via the local dispatcher by the Service Center and in 29 cases (5.2%) the emergency ambulance.
