傳統(tǒng)動物心電圖測量分析采用體表無創(chuàng)方式，雖操作簡單，但是存在測量位置影響大、測量精度不高等局限性，而心外膜表面電極測量心電圖操作極為復雜且創(chuàng)傷性大，實驗中較少采用。為解決這一難題，Scisence 提供微創(chuàng)的多電極電生理導管，獨特設計使研究者能夠對生物電在整個心臟的擴散過程進行更為深入的測量和分析。

電生理導管系統(tǒng)由八電極電生理導管、電極分配盒及第三方生物電放大器及刺激器組成。

工作原理：八電極電生理導管上的每對電極均受控于電極分配盒，電極分配盒通過 2mm 針式連接線與第三方生物電放大器或刺激器相連，通過生理記錄儀采集對應的電極對引導的電信號數(shù)據(jù)。八電極電生理導管可用于心臟起搏，電信號記錄，進而用于心臟電生理的各方面研究。

電生理導管系統(tǒng)特點

1. 微創(chuàng)八電極電生理導管，可監(jiān)測心內(nèi)各個部位的心電信號

2. 可同時引導心內(nèi) 4 個不同部位的心電信號，可觀察心電信號的擴散過程

3. 同一根導管可同時用于采集信號和給予刺激

4. 小鼠 1.1F，電極間距 0.5mm；大鼠 1.9F，電極間距 1.0mm；導管電極間距可定制

5. 聚酰胺材料制作，生物相容性好，兼顧靈活性和剛性，光滑而便于插入

6. 電極分配盒控制每對電極，電極之間互不影響

7. 兼容多種第三方生物電放大器、刺激器、數(shù)據(jù)采集器，如美國 iWorx 的 iWire-BIOx、IX-RA-834 等

8. 動物實驗用，不能用于人體
