英文摘要

His bundle electrogram (HBE) recording is an important method for studying the atrioventricular conduction system. However, the current HBE recording methods in isolated animal hearts have some shortcomings, such as unstable recording due to the difficulty in fixing electrodes as a result of intense heart beating, the small amplitude of the His signal or the possibility to destroy the integrity of heart structure. In order to overcome these shortcomings, we designed and manufactured reliable, inexpensive and easy-made bipolar cannula electrodes, which combines the functions of Langendorff-perfusion aortic cannula and recording electrodes. With the cannula electrodes, the operation of HBE recording becomes easier and the clearer and more stable recording can be obtained in isolated rat hearts.
