The DiCare m1C series micro ambulatory ECG recorders are designed for recording, measuring, monitoring ECGs by users themselves anywhere, anytime and in any movements, so that users' heart functions can be evaluated promptly to reduce the risk of serious cardiac accidents, especially when they are not reachable to professionals. The ECG recordings can be brought to professionals later when possible for diagnostic references, or transferred to professionals via HHM network platform for prompt reading and analysis.
