A normal patient monitoring system gives us only the feedback about crossings of some vital low or high threshold levels, without comprising specific diagnosis content. In a life-threatening situation, the physician’s required reaction time can be reduced by preparing proper equipment in advance for some specific processing, which may
significantly increase the patient’s chances of surviving. This is a major advantage in the field of remote exploration.Therefore, it is important to have a low power consumption system that can give early diagnostic data in health monitoring. This feature might be critical in case of an eventual data transmission failure between the patient and the
monitoring host PC. Our experiments did establish that in case of the ECG signals, it is possible to take a diagnostic decision even at a local low-power embedded system.
