Abstract

The invention relates to a cardiac electric pacing pulse signal detecting device. The cardiac electric pacing pulse signal detecting device comprises a pacing pulse signal detection unit and a comparing unit, wherein the pacing pulse signal detection unit is used for screening pacing pulse signals from an electrocardiosignal channel, converting the pacing pulse signals into positive and negative pulse pairs with a zero crossing point and transmitting the obtained pulse pairs to the comparing unit; the comparing unit is used for respectively comparing positive and negative vertex levels of the inputted pulse pairs to set positive and negative threshold values; and comparison results are in parallel connection to obtain marker bits judging whether the cardiac electric pacing pulse signals on the electrocardiosignal channel exist or not. The invention also relates to electrocardiogram equipment using the cardiac electric pacing pulse signal detecting device. The cardiac electric pacing pulse signal detecting device and the electrocardiogram equipment thereof have the advantages of high judgment and antijamming capability and accuracy.

Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to a detection device for cardiac pacing pulse signals and electrocardiogram equipment. Background technique

[0002] Cardiac pacing pulse signal, that is, PACE signal, is sent by the pulse generator and transmitted to the myocardial tissue through the wire connection system to stimulate the myocardial tissue, thereby causing the heart to produce strong contraction and expansion. It appears as a very short linear wave signal on the surface ECG. Since the signal appears regularly on the body surface ECG, takes up a very short time, is perpendicular to the equipotential line (baseline) of the ECG, and has different amplitudes on each lead, showing a straight up and down linear mark, also known as It is the pacing spike signal. In the actual electrocardiogram equipment, its pacing pulse generator regularly sends out pulses according to the preset frequency to obtain the signal. The ...
