A Reconfigurable Overlapping FFT/IFFT Clears out to De-Noise an ECG Signal

Abstract

Continuous ECG tracking the usage of telemetry, or Holter tracking, or both, are normally
accomplished in patients . Electrocardiography tracking lets in the noninvasive assessment of
a suspected arrhythmia for the duration of ordinary every day actions. ECG indicators
received from Holter structures typically comprise a number of noises and artifacts. A
reconfigurable overlapping FFT/IFFT clear out out for ECG records acquired from a Holter
tracking device is presented. The Holter tracking device used on this paintings consists of an
analogue front-end (primarily based totally at the ADS1298 chip), a microprocessor
(STM32L151) and an FPGA chip as a co- processor. The ECG indicators are amplified and
sampled via way of means of the ADS1298, then the sampled records are processed via way
of means of the FPGA unit. The reconfigurable overlapping FFT/IFFT clear out out is used
for eliminating power-line interference and high-frequency artifacts. The proposed technique
is straightforward and smooth to implement.
