Abstract - In this work, we have applied two recent methods; the Discrete Wavelet Transform (DWT) and the Empirical Mode Decomposition (EMD) combined with the Hilbert transform, to the heart rate variability (HRV) considered ...

A low-voltage low-power pacemaker Front-End for detecting QRS complex is presented in this paper. The circuit includes a switched-opamp switched-capacitor (SO-SC) preamplifier with a gain of 40db, a fourth-order Butterworth ...
