Description

Apparatus for measuring biological signals and method for monitoring subjects using the same {AN ELECTRO CARDIOGRAM MEASURING SYSTEM AND THE ARRESTED MONITORING METHOD OF USING THIS}

The present invention relates to a device for measuring a biological signal of a human, and more particularly, to measure and analyze the electrocardiogram (hereinafter referred to as 'biological signal') for a subject in real time, and display the result of the measurement. The present invention relates to a biosignal measuring apparatus and a method for monitoring a subject using the same, which transmit the result to a hospital or emergency center located at a remote location through a wireless communication network.

The electrocardiogram is a mechanical representation of the electrical activity of the heart that performs the pumping function of the living body, that is, the electrical phenomena due to the electrical discharge (excitement) and charge (recovery state) generated from the heart. It is called an electrocardiogram.

Unlike the skeletal muscle cells of the body, the muscle cells of the heart have characteristics that cause dogmatic motility stimulation. This automatism and the cellular electrical activity of the myocardium result in cardiac motility.

When one cardiomyocyte is removed, the contraction and relaxation of the heart is caused by the discharge (intracellular inflow of Na) and charge (extracellular K release) through the electrical activity of K, Na, and Ca inside and outside the cell membrane. It happens over and over again, and the electrical potential derived from this is transmitted to the surface of the body to measure and visually record the waveform is called an electrocardiogram.

ECG is detected by the measurement of P, Q, R, S, and T waves. P wave detects atrial depolarization and contraction, which is due to an increase in autonomy in the freezing section, an increase in the freezing section potential, and electrical stimulation from the freezing section. ) Means passing through the atrioventricular nodules.

Q wave detects ventricular septal depolarization, R wave detects ventricular depolarization, or excitatory process of ventricular muscle, and S wave detects ventricular base depolarization, that is, ventricular muscle on the opposite side of the electrode (e.g. electrode If it is present, the right ventricle, and if the electrode is in the right ventricle, the left ventricle) to detect the excitation process, T wave is to detect the ventricular repolarization, that is, the end of the ventricular process.

The electrocardiogram, which detects and visually records the P, Q, R, S, and T waveforms, which are active currents according to the expansion of the contraction of the heart muscle, is used to confirm the abnormality of the heart and It is used as a basic method for measuring diseases, and occupies a very important position among medical device roles.
