Description
Technical field
The present invention relates to heart signal field of measuring technique, survey more particularly to a kind of signal for Intracoronary ECG
Measure device.
Background technique
Electrocardiogram is to record the variation figure of electrical activity caused by heart each cardiac cycle from body surface using electrocardiograph
Technology.Electrocardiogram be it is clinical it is most common one of check, for various arrhythmia cordis, ventricular atrial hypertrophy, myocardial infarction,
The illnesss inspection such as myocardial ischemia.
Electrode is placed in human body different parts, to record and react the electrical activity of heart.When routine electrocardiogram of being expert at checks,
Usually only place 4 limb leads electrodes and V1~V66 Precardial lead electrodes record conventional 12 lead electrocardiogram.Wherein electrocardio
ST sections of changes of figure are main aspects whether judging heart normally.
Intracoronary ECG (IC-ECG) is compared with surface electrocardiogram, since the electrode of catheter head is located in coronary artery, more
The electric field generated close to ischemic region Electrical Activity of Myocardial Cells, potential change records relatively sharp.Intracoronary ECG and the body surface heart
Electrograph is compared according to even higher sensibility, can the small electrical activity variation of reflecting myocardium.Have for Accurate Diagnosis heart condition
Important meaning.
Currently, existing meter Intracoronary ECG (IC-ECG) by seal wire measure electrocardiosignal, by coronary guide wire send to
The distal end IRA, seal wire end are connected by crocodile clip with precordial leads V2, and Intracoronary ECG is recorded.It is in the prior art to lead
Silk structure is too simple, is unfavorable for operating.
