Technical Field
The utility model relates to a heart signal measurement technical field specifically relates to a signal measurement device for an electrocardiogram in coronary artery.
Background
Electrocardiography is a technique for recording a pattern of changes in electrical activity generated every cardiac cycle of the heart from the body surface by using an electrocardiograph. The electrocardiogram is one of the most commonly used clinical examinations and is used for examining various arrhythmia, ventricular atrial hypertrophy, myocardial infarction, myocardial ischemia and other diseases.
Electrodes are placed at various locations in the body to record and reflect the electrical activity of the heart. In the course of conventional electrocardiographic examination, only 4 limb lead electrodes and V are usually placed1～V66 precordial lead electrodes for recording conventional 12-lead electrocardiogram. The ST segment change of the electrocardiogram is the main aspect for judging whether the heart is normal or not.
Compared with a body surface electrocardiogram, the coronary artery electrocardiogram (IC-ECG) has the advantages that the electrodes at the head of the catheter are positioned in the coronary artery and are closer to an electric field generated by the electrical activity of myocardial cells in an ischemic area, and the potential change record is clearer. Compared with the body surface electrocardiogram, the coronary artery internal electrocardiogram has higher sensitivity and can reflect the tiny change of the electrical activity of the cardiac muscle. Has great significance for accurately diagnosing the heart condition.
Currently, the existing coronary electrocardiogram (IC-ECG) meter measures an electrocardiographic signal through a guide wire, the coronary guide wire is sent to the far end of IRA, the tail end of the guide wire is connected with a precordial lead V2 through an alligator clip, and the coronary electrocardiogram is recorded. The guide wire in the prior art is too simple in structure and not beneficial to operation.
