Standard three-lead electrocardiogram monitor system based on wireless sensor network

Abstract

A standard 3-lead electrcardiographic (ECG) monitoring system which is based on a wireless sensor network, comprising a management center, a patient monitor node, a sensor network node which is composed of a patient monitoring node and a collective node, and a digital processing terminal, wherein, the patient monitoring node communicates with the collective node; all the collective nodes communicate with each other; the collective node, the digital processing terminal and the management center communicate with each other. The patient monitoring node comprises a sensor input unit, a data processing unit, a data transmission unit and a power unit which are connected with each other in sequence; the data processing unit, the data transmission unit and the power unit are connected with the collective node. The invention combines the wireless sensor network and the ECG monitoring digitization, the disease rate can be predicted effectively by only carrying one monitoring patient node, which provides an important objective base for clinical analysis. The system achieves the combination of the standard 3-lead synchronous ECG, and variability of cardiac rate, etc., and can display a complete figure on which an identical cardiac cycle is on different orientations and different leads.

Description

technical field [0001] The invention relates to an electrocardiographic monitoring system. In particular, it involves a standard three-lead ECG monitoring system based on a wireless sensor network that combines wireless sensor network technology with digital ECG monitoring to construct a hospital's digital ECG network. Background technique [0002] In recent years, my country's hospital digital construction has made great progress. Many hospitals have developed from a management information system centered on financial management to a patient-centered clinical information system, and gradually built clinician workstations, PACS and LIS, etc. Information systems of a clinical nature. However, as a routine examination of the electrocardiogram, its digital construction has not attracted enough attention. Conventional ECG monitors or ECG workstations currently available in hospitals generally have disadvantages such as bulky, single-function, inconvenient to use and inconvenien...

Problems solved by technology

[0006] ③ The diagnostic coincidence rate of ECG for myocardial infarction was only 86.9%, and the diagnostic coincidence rate for lateral wall myocardial infarction was even worse, only 25%

[0007] (2) The body surface ECG also has certain difficulties in judging some complex arrhythmias, and sometimes the body surface ECG is difficult to distinguish

[0008] (3) When the body surface ECG cannot accurately judge atrioventricular block, the block site is the atrioventricular node or the bundle of Hirsch.

[0009] (4) The surface electrocardiogram is not helpful for the study of some special electrophysiological phenomena of the heart, such as occult conduction, supernormal period conduction, etc.

[0010] (5) The conventional resting ECG recording time is too short to capture transient arrhythmias and ST-T changes

[0013] British Numed Holding Co., Ltd. has developed the PocketView ECG product. The PocketView ECG electrocardiogram monitoring system realizes the display and query based on PDA, but the PDA and the lead wire are connected through a controller box, and it does not support wireless sensor networks.
