Description

用于冠脉内心电图的信号测量装置Signal measuring device for intra-coronary electrocardiogram 技术领域Technical field
本发明涉及心脏信号测量技术领域，具体地涉及一种用于冠脉内心电图的信号测量装置。The present invention relates to the technical field of heart signal measurement, and in particular to a signal measurement device for intra-coronary electrocardiogram.
背景技术Background technique
心电图是利用心电图机从体表记录心脏每一心动周期所产生的电活动变化图形的技术。心电图是临床最常用的检查之一，用于对各种心律失常、心室心房肥大、心肌梗死、心肌缺血等病症检查。The electrocardiogram is a technology that uses an electrocardiograph to record the changes in the electrical activity of the heart during each cardiac cycle from the body surface. The electrocardiogram is one of the most commonly used clinical examinations, used to check various arrhythmia, ventricular atrial hypertrophy, myocardial infarction, myocardial ischemia and other diseases.
在人体不同部位放置电极，以记录和反应心脏的电活动。在行常规心电图检查时，通常只安放4个肢体导联电极和V 1～V 66个胸前导联电极，记录常规12导联心电图。其中心电图ST段改变是判断心脏正常与否的主要方面。 Electrodes are placed on different parts of the human body to record and reflect the electrical activity of the heart. In routine ECG examination, usually only 4 limb lead electrodes and V 1 to V 6 6 front chest lead electrodes are placed, and the conventional 12-lead ECG is recorded. The ST segment change of electrocardiogram is the main aspect to judge whether the heart is normal or not.
冠脉内心电图(IC-ECG)与体表心电图相比，由于导管头部的电极位于冠脉内，更接近缺血区心肌细胞电活动产生的电场，电位变化记录更为清晰。冠脉内心电图与体表心电图相比据偶更高的敏感性，能反映心肌微小的电活动变化。对于准确诊断心脏情况具有重大意义。Compared with the body surface electrocardiogram, the intracoronary electrocardiogram (IC-ECG) is located in the coronary artery and is closer to the electric field generated by the myocardial cell electrical activity in the ischemic area, and the potential changes are recorded more clearly. Compared with the body surface ECG, the intra-coronary electrocardiogram has a higher sensitivity and can reflect the small changes in the electrical activity of the myocardium. It is of great significance to accurately diagnose the heart condition.
目前，现有的计冠脉内心电图(IC-ECG)通过导丝测量心电信号，将冠脉导丝送至IRA远端，导丝末端通过鳄鱼夹与胸前导联V2相连接，记录冠脉内心电图。现有技术中的导丝结构过于简单，不利于操作。At present, the existing coronary intra-coronary electrocardiogram (IC-ECG) uses a guide wire to measure the ECG signal, and sends the coronary guide wire to the distal end of the IRA. The end of the guide wire is connected to the anterior chest lead V2 through an alligator clip for recording Coronary ECG. The guide wire structure in the prior art is too simple, which is not conducive to operation.
