The current techniques used to diagnose cardiac arrhythmias such as Holter, Rtest and telemetry systems are partially efficient because they are limited either in time or in space. In this paper, a platform dedicated to the real‐time remote continuous cardiac arrhythmias detection and monitoring is proposed. Such a platform allows to improve the accuracy and the efficiency of the diagnostic of ventricular tachycardia among the high‐risk patients and enables the implantation of ICD to prevent sudden death. The new method allows the patient to lead a normal life while being remotely monitored in real‐time by an ambulatory wireless ECG sensor. When a cardiac arrhythmia is detected a message including a sequence of ECG signals and the patient's images (indoors only) is sent to a remote surveillance server. According to the gravity of the symptom, the cardiologist can intervene in real time or later. The system has been evaluated on some ten patients with regard to heartbeat and cardiac rhythm disturbance. The real‐time results are similar to those offered by HP telemetry systems.
