In this paper a practical and fast R waves detection algorithm based on DSP processor is proposed.According to the characteristics of R waves in ECG and the principle of length transformation,calculations of difference plus sliding window integration are applied to the ECG data.Then detection threshold and blind area are dynamically adjusted according to characteristics of ECG signals.This real time detection algorithm,which can be implemented on a DSP processor of TI company,has good detectability for R waves.By means of detection of typical ECG data of MIT BIH database,it can be shown that the algorithm can meet requirements of ECG data anlysis.
