The pacemaker electrode duct comprised of an electrode duct and a function selecting operation box is characterized in that the electrodes are mounted at the end of the duct and can be bended into an angle of 0-90 deg. in esophaqus near the ventricle to shorten the distance between the electrodes and cardiac muscle; the operation box has control Rnobs and switches to indicate the bending angle and select a fixed angle and the combination of the electrodes. The duct is safe, simple and multifunctional, and is suitable for ventricle pacemaking, defibrillation, electrocardio signal monitoring and treating arrhythmia. |
