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 (Ventricular Fibrillation, VF), etc., may generate false alarms

Embodiment Construction

[0045] The present invention provides an arrhythmia detection device, which can trigger echocardiogram detection when the monitor detects arrhythmia signal or generates an alarm of asystole, ventricular tachycardia, and ventricular fibrillation. Features, can intuitively reflect the movement state of the heart. Aiming at the fact that ECG monitoring may generate false arrest alarms, echocardiographic data is used to corroborate ECG monitoring results, which reduces the generation of false alarms.

[0046] see figure 1 , a device for detecting arrhythmia provided by Embodiment 1 of the present invention, comprising:

[0047] At least one ultrasonic probe 22 that can be fixed on the patient's body surface is used to transmit ultrasonic waves to the measured object, and perform ultrasonic scanning monitoring on the heart of the measured object; in specific implementation, the ultrasonic probe 22 is directly attached to the measured object At a fixed position on the body surface...

Abstract

An arrhythmia detection device, comprising: an ultrasound probe (22) fastened on the body surface of an object under test, and used to conduct ultrasound scan monitoring on the heart of the object under test; a monitoring probe (20) for probing ECG parameters of the object under test; an ultrasound function module (12) for receiving a cardiac ultrasound signal obtained by the ultrasound probe (22); a monitoring function module (10) for acquiring the ECG parameters of the object under test; an ultrasound information display unit (32) for displaying cardiac ultrasound parameters; a monitoring information display unit (30) for displaying the ECG parameters; and an arrhythmia trigger module (17) for triggering the ultrasound function module (12) to conduct ultrasound scan monitoring via the ultrasound probe (22) on the heart of the object under test.

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...
