The newest Bluetooth communication technology was added to our previously developed Internet based injormation system, wich collects the short-and longterm digitized ECGs with the relevant clinical data for the management of the patients. A wireless communication protocol was developed using the Bluetooth system for a short distance (10-20m) radiofrequency data transmission. This unit could send compressed records to a WEB Server via GSM phone modem. During the study 3850 ECG based telemedicine consultations took place. I663 ambulatory monitoring with on-line monitoring via the Internet were done. The thrombolysis time-delay in acute myocardial was studied of 36 patients, home telecaring was done in 39 patients with acute myocardial infarction immediately ajer the hospital discharge, and monitoring in a nursing hospital was used.

The left ventricular diastolic and systolic functions were assessed in 27 strictly selected type 1 diabetic patients without overt heart disease and 50 age- and sex-matched control subjects. For evaluating left ventricular performance, complex mechanocardiography including digitized apexcardiography was used at rest and after symptom-limited, graded dynamic exercise. The values of diastolic/systolic time intervals and amplitude parameters did not differ significantly between the diabetic and control groups at rest. A longer value of corrected early apexcardiographic relaxation time (diabetics: 38.7 ± 2.6 ms, controls: 17.3 ± 2.1 ms, p < 0.001) and a smaller normalized amplitude of relaxation (diabetics: 0.014 ± 0.004 ms^-1, controls: 0.056 ± 0.006 ms^-1, p < 0.001) were observed after dynamic exercise suggesting disturbances of the early diastole in diabetic patients. No correlations could be found between the diastolic abnormalities and the diabetic control. Significant correlation was observed between the diastolic disorders and the duration of diabetes mellitus. Testing left ventricular performance by complex mechanocardiography including digitized apexcardiography after dynamic exercise in patients with type 1 diabetes might be useful for recognizing diastolic abnormalities even when no alterations could be identified at rest. Diastolic disorders could appear in diabetic patients without overt heart disease and clinical symptoms. Left ventricular systolic function might be normal, although exercise-induced alterations of diastolic function might already be present in type 1 diabetic patients.
