The Vitaphone Tele-ECG-card 100 IR is a credit card-sized device weighing just 37 grams, enabling the patient to manually record up to three electrocardiograms – anytime, anywhere, simply at the touch of a button – and to easily transmit this data via mobile or landline telephone to his doctor in a matter of seconds for the accurate, cost-effective remote diagnosis of symptomatic heart-rhythm problems. Advantage: the patient is always connected and can be monitored long-distance in an efficient and cost-effective way. The 3-channel Vitaphone Tele-ECG-Loop-Recorder 3300 BT and the 1-channel version (3100BT) both automatically record and transmit symptomatic and asymptomatic heart-rhythm event data. They can be programmed with patient-specific upper/lower thresholds for a number of important cardiological parameters and constantly monitor the patient over a long period of time, recording new data and overwriting older data in a continuous loop (much like an aircrafts flight recorder).
