Filter by:Bradyarrhythmia is one of the common diseases. Also, bradyarrhythmia could result in syncope, clinic convulsion, shock, sudden death and so on, which could influence people's life quality severely. Artificial pacemaker is the only way that can cure bradyarrhythmia. However, traditional right ventricular apical pacing, because its electric stimulation is mostly different of the physiological one, could lead to ventricular thick inhomogeneously. At the same time, traditional right ventricular apical pacing also could result in cardiac arrhythmia and fibrosis, dyssynchrony of the ventricles, which can increase the volume of mitral regurgitation. Besides, cardiac resynchronization therapy (CRT), which aims to cure chronic heart failure, is also unsatisfactory. On the contrary, the electric stimulation of his bundle pacing (HBP) is the same as the physiological one, which produces a relatively normal electrical stimulation and synchrony in systolic velocities in ventricular. Thus, HBP could produce a better haemodynamic effect, which is the hotspot in pace-making area recently. The purpose of this study is to conduct a comparison in patients' cardiac function, ECG, and pacemakers' threshold value, time limit and so on among dual chamber pacemaker and HBP.
