Embodiment 1

[0030] Embodiment 1, myocardial excitation and contraction coupling time diagnostic instrument and its detection

[0031] 1. Myocardial excitation and contraction coupling time diagnostic instrument

[0032] The myocardial excitation-contraction coupling time diagnostic instrument of the present invention is as figure 1 As shown, it includes an ECG acquisition unit for detecting electrical excitation of the myocardium and an echocardiography acquisition unit for detecting myocardial contraction activity.

[0033] Wherein, the ECG acquisition unit includes electrodes, an amplification circuit connected to the electrodes, and an analog-to-digital conversion module connected to the amplification circuit. The working process of the electrocardiographic acquisition unit is as follows: the electrodes detect the electrocardiographic activity, and then transmit the electrical signal to the amplification circuit connected to the electrode, and then the amplified signal is transmitted ...

Abstract

The invention discloses a myocardial excitation contraction coupling time diagnostic apparatus and application thereof. The diagnostic apparatus provided by the invention comprises an electrocardio collection unit, an ultrasonic heartbeat collection unit, an analysis processing unit and a data output unit, wherein the electrocardio collection unit is used for defecting myocardial electrical excitation; the ultrasonic heartbeat collection unit is used for detecting myocardial contraction; the analysis processing unit is used for recording the starting time of the myocardial electrical excitation detected by the electrocardio collection unit and the starting time of the myocardial contraction detected by the ultrasonic heartbeat collection unit and analyzing the time interval between the starting time of the myocardial electrical excitation and the starting time of the myocardial contraction; and the data output unit is used for outputting data obtained by the analysis processing unit. Experiments prove that the coupling delay time of the heart failure patients is markedly longer than that of the healthy volunteers so that the coupling delay time displayed by the diagnostic apparatus disclosed by the invention can be used for evaluating the heart function.

Description

technical field [0001] The invention relates to a medical device, in particular to a cardiac excitation-contraction coupling time diagnostic instrument and its application. Background technique [0002] In the current clinical medicine, there is a lack of specialized equipment for early heart failure diagnosis, which makes heart failure patients often miss the critical period of early treatment. This instrument fills the gap above and provides an effective method for the diagnosis of heart failure, especially early heart failure. Contents of the invention [0003] The purpose of the present invention is to provide a diagnostic instrument for coupling time of myocardial excitation and contraction. Heart failure can be diagnosed by using the diagnostic instrument, and early heart failure diseases can be found in time. [0004] The myocardial excitation-contraction coupling time diagnostic instrument provided by the present invention includes: [0005] An electrocardiograp...
