Abstract: Researching a method to monitor the electrocardiogram signal abnormity
and give an alarm automatically though short information 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.
