For the convenience of the following, the working principle of the bronchial catheter which can be used for ECG pacing defibrillation monitoring can be better described. Rationally, a brief description of the body position of the human body:

From the anatomical view of the human body, the bronchial bifurcation is at the same level as the bottom of the heart and the four thoracic vertebrae, with the heart in front and the bronchial bifurcation in the back, very close. If the bronchial catheter with electrodes is inserted into the right bronchus through the oral cavity, the pulse current of the cardiac pacemaker or cardiac electrophysiological stimulator can stimulate the atrial to cause pacing, making the heart rhythm with the cardiac electrophysiological stimulator.
