APPARATUS FOR MONITORING BRONCHIAL ELECTROCARDIOGRAM

摘要

An intrabronchial catheter has an inflatable balloon with the bronchial ECG lead electrodes. Upon inserting the intrabronchial catheter into the trachea or bronchus of a human body, air is supplied to the balloon so that the balloon is stably retained in the trachea or bronchus, thereby bringing the bronchial ECG lead electrodes in close contact with the internal wall surface of the trachea or bronchus so as to effectively monitor bronchial electrocardiogram.
