摘要：
#$%^&*AU2020101099A420201008.pdf#####Abstract of Descriptions The invention discloses a heart failure animal model for implanting pacemakers through an external jugular vein under the guidance of B-ultrasound, which comprises a heart failure animal model, a pacemaker, a spiral electrode, an exfoliative sheath, an electrophysiological recorder and a cardiac ultrasonic instrument, wherein the spiral electrode is inserted into the exfoliative sheath, the exfoliative sheath pulls the spiral electrode, a heart is arranged in the heart failure animal model, and the inner end of the spiral electrode is positioned at a right ventricle implantation position of the heart； According to the invention, the cardiac ultrasonic instrument is used for positioning, stimulation is sent through the electrophysiological recorder, the inner end of the spiral electrode is implanted into the right ventricle of the heart according to the voltage of the electrophysiological recorder, the implantation position of the spiral electrode is determined when the waveform of the pacing electrocardiogram displayed by the cardiac ultrasonic instrument is a wide deformed QRS wave, and meanwhile, when the heart rate displayed by the electrophysiological recorder is consistent with the pacing frequency, the spiral electrode is fixed on the right ventricular muscle of the heart, so that the implantation position is convenient to determine.Drawings of Descriptions 2 4 Figure 1 1 Figure 2 1/2
