Researching a method to monitor the electrocardiogram signal abnormity and give an alarm automatically though short informa-tion of GSM mobile telephone. The article analyzed how to make up the system by electrocardiogram signal circuit, single chip, mobile telephone, interface circuit and the GSM-SMS-AT program. The system adopts the combinative method of local maximum, local minimum and slope to judge cardiogram abnormity; selects inner resourceful MSP430F449 single chip to meet the system demand for low power consume, small volume, using convenient. The model of cancel button can avoid misinformation alarm. Thus, the system reliability and practicability is better. By dint of the abroad using GSM mobile telephone not expert wireless module, the cost of monitor drops more. It is convenient for home monitor of cardiogram. Control experiment with general electrocardiograph, the result indicates the system meets the request of sickroom wardship and no misinformation alarm. The experiment proves the method is doable.
