Rat electrocardiography (ECG) is frequently used in biomedical research as a model for exploring heart function in a wide variety of experimental conditions. Subcutaneous ECG is a common approach to record rat heart rhythm using implanted needle electrodes to sense the rat ECG signals with the animal under deep anesthesia. However, such an invasive measurement could cause inconvenience due to cumbersome animal preparation, and the anesthetics are likely to interfere with the autonomic regulation of cardiac rhythm. Most studies used the galvanic contact between animal limb and electrode sensing surface to record cardiac signals from small animals. However, the non-contact approach of capacitive ECG sensing for small laboratory animals has not been extensively investigated. This study aims to develop a non-contact ECG system to promote the ECG measurement of laboratory animals for biomedical research. The method utilizes the capacitive coupling technique to detect cardiac signals ...

用于小动物ECG记录的非接触式电容感应

大鼠心电图(ECG)在生物医学研究中经常用作探索各种实验条件下心脏功能的模型。皮下ECG是使用植入式针电极在深麻醉下与动物感应大鼠ECG信号的记录大鼠心律的常用方法。但是,由于动物准备工作繁琐,这种侵入性测量可能会带来不便,并且麻醉药可能会干扰心律的自主调节。大多数研究使用动物肢体与电极感应表面之间的电流接触来记录来自小动物的心脏信号。但是,尚未广泛研究用于小型实验动物的电容式ECG感应的非接触式方法。这项研究旨在开发一种非接触式ECG系统,以促进用于生物医学研究的实验动物的ECG测量。该方法利用电容耦合技术来检测心脏信号...
