WebJun 12, 2013 · The method of HPF (high pass filter) has been used for separating heart signal components from a respiratory fluctuation component [8, 9]. However, this method cannot separate the harmonic components from the respiratory variation, and it is hard to reproduce heart rate waveform and measure the heart rate [ 10 ]. Webdamaged heart muscle in specific areas. ECGs work by detecting and amplifying the tiny voltage changes on the skin that are caused when the electrical signal in the heart muscle is charged and spread during each heartbeat. The signal recorded as the difference between two potentials on the body surface is called an “ECG lead”.
