[Broad-band analogue-to-digital converter of electrocardiograms]
Abstract:
The use of a broad-band analogue-to-digital converter (ADC) with a reading rate of up to several kilohertz and with a subsequent digital filtration and decimation provides for obtaining the amplitude-and-frequency characteristics with the parameters, which are virtually unachievable for the ordinary analogue scheme technologies or digital filters inbuilt into the digital-filter integral ADC. Multi-digit ADC and digital signal processors (DSP) are used for the purpose. Additionally, with DSP it is possible to process algorithms of the broad-band ECG, like isolation of the impulse of the cardiac pacemaker.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage. When...
