Theoretical algorithm complexity is also provided. Our simulation study supposes that the ECG signal is already digitized and available within a computer platform. We perform 1000 000 Monte Carlo experiments using the same input files leading to average results that point out drawbacks and advantages of each score. Since all these calculations do not require either large memory occupation or long processing automatic estimation is compatible with real-time requirements associated with AMI urgency and with telemedicine systems being faster than manual calculation even in the case of simple costless personal microcomputers.

INTRODUCTION In 2004 AMI was responsible for 22.93 of deaths associated with cardiovascular diseases which represents 6.39 of the total number of deaths in Brazil 1 . In .
