An arrhythmia detection device

Abstract

The present invention provides an arrhythmia detection device, comprising: at least one ultrasonic probe that can be fixed on the body surface of a patient to perform ultrasonic scanning and monitoring on the heart of the measured object; a monitoring probe for detecting the electrocardiographic parameters of the measured object; The function module is used to receive the cardiac ultrasound signal obtained by the ultrasound probe; the monitoring function module is used to obtain the ECG parameters of the measured object; the ultrasound information display unit is used to display the cardiac ultrasound parameters; the monitoring information display unit is used to display the cardiac parameters. The electric parameter; the arrhythmia triggering module is used to trigger the ultrasonic function module to perform ultrasonic scanning monitoring on the heart of the measured object through the ultrasonic probe. Implementing the present invention can trigger an echocardiogram detection when the monitor generates an alarm for asystole, ventricular tachycardia, and ventricular fibrillation, and further determine the state of cardiac arrest, ventricular tachycardia, and ventricular fibrillation through the images and parameters reflected by the echocardiogram. Provide accurate arrhythmia monitoring results for clinical practice.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an arrhythmia detection device. Background technique [0002] Asystole is a type of arrhythmia with high severity. At present, the monitor realizes the alarm function of asystole, and needs to meet the following five conditions: [0003] 1) The monitor supports arrhythmia analysis function; [0004] 2) The ECG lead wires are correctly connected to the subject; [0005] 3) The switch status of the arrest alarm is on; [0006] 4) The ECG signal voltage detected by the monitor is lower than the arrest threshold (low voltage ECG signal); [0007] 5) The duration of the low-voltage ECG signal exceeds the set threshold. [0008] According to the triggering conditions of the arrest alarm, it is known that any factor that can cause a low-voltage ECG signal of sufficient duration may generate an arrest alarm, which inevitably leads to some false arrest alarms. The reasons for the ar...

Problems solved by technology

[0009] 1) The ECG lead wire is not connected properly, resulting in excessive resistance between the electrode pad and the subject's skin;

[0010] 2) The ECG signal is too weak due to incorrect connection position of the ECG lead wire;

[0011] 3) Electromagnetic interference from the environment causes the detected ECG signal to be too weak;

[0012] 4) Other reasons that may cause false alarms of cardiac arrest

[0013] Based on the above analysis, it is known that the arrhythmia analysis method of the monitor may still cause detection errors in the detection of asystole, and then generate false alarms. Not only that, but also in other arrhythmias, such as Ventricular Tachycardia (VT ), Ventricular Fibrillation (VF), etc., may generate false alarms
