Comarch Teleholter is a system built with the aim of introducing a new quality in ECG Holter tests. Each phase of the test is characterized by telemedicine functions. Owing to the integration with the Comarch e-Care system, patients can be monitored during the test, with all heart rate irregularities being reported in real time to paramedics at the Remote Medical Care Center. After the test, files containing the ECG signal record are transmitted to the Comarch Healthcare server and stored in accordance with the regulations governing personal and medical data security. From then, the test is available for analysis by the doctor indicated by the medical personnel transmitting the data. The doctor can access the server hosting the advanced application for ECG signal analysis from anywhere with Internet access. In case of doubts, or if another specialist needs to be consulted, the test can be transmitted by a single click. If the clients prefer not to employ their doctors to analyze ECG tests, or need support in this area, they can request an interpretation of Holter test results from specialists at Centrum Medyczne iMed24 in Krakow, a Comarch Healthcare partner. When the final test report has been approved by the analyzing doctor, the report is immediately made available to all operators (medical staff from the center where the test was performed). Because all data is stored on the Comarch Healthcare servers, each report, complete with test information, will still be available many years later.
