MATLAB was used to analyze and process ECG dataset gotten from Physionet online database with focus on R-R peaks to calculate the heartbeat, by applying high pass filtering and squaring the signal.

Apr 26, 2006 · My ECG simulator is a matlab based simulator and is able to produce normal lead II ECG waveform. The use of a simulator has many advantages in the simulation of ECG waveforms. First one is saving of time and another one is removing the difficulties of taking real ECG signals with invasive and noninvasive methods. Fig. 6, Fig. 7 represent Matlab simulation for the denoising block, the Matlab simulation is done for ECG signal comes from MIT-BIH DB (record 115) for 40 s length. Fig. 6 represents the ECG signal suffers from the baseline wander before input to the denoising block, while the ECG signal after baseline wander removal using LLFE is shown in Fig. 7.
