Brief Summary

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.

Dual chamber pacemaker

ACTIVE COMPARATOR

1. Patients with sinus node disfunction: sinus node disfunction with obvious clinical symptoms, including sinus pause; patients with chronotropismus disfunction; patients have to take some medicine due to some diseases, but the medicine may result to sinus bradycardia. 2. Adult Acquired Atrioventricular Block (AVB): (1). Third degree or advanced atrioventricular block in any block part with symptomatic bradycardia (2). Patients taking other antiarrhythmic drugs in long term, which could result in third degree or advanced AVB (in any block part) and symptomatic bradycardia; 3. Patients with acute myocardial infarction (AMI) and AVB: (1). Patients with His-Purkinje system persistent second degree AVB and retardant or third degree AVB after STEMI; (2). Patients with temporary severe second degree AVB or third degree AVB (block part under atrioventricular node) and retardant; 4. Patients with carotid sinus hypersensitivity or neurogenic syncope of the heart;

Interventions

Dual Chamber Pacemaker DEVICE

1\. Conducting venipuncture. Subclavian vein is our first choice. Then we set up two venous channels and implant two guiding wires into postcava. 2.Putting 2 sheathing canals into heart along with guiding wires. 3.Locating the sheathing canals, and putting electrodes into canals. 3.Adjusting the electrodes and revolving them anticlockwise to lead them to right atrium and right ventricle respectively under the X-ray. 4.Immobilizing electrodes. 5. Some ways to determine whether the electrode is fixed or not: the head of the electrodes could beat rhythmically with atrium or ventricle or by testing damage current. 6.Removing the canals and suturing.

His Bundle Pacemaker DEVICE

1.Conducting venipuncture. Subclavian vein is our first choice. Then we set up two venous channels and implant two guiding wires into postcava. One of the guide wire is 120cm in length, 0.035 or 0.038 in diameter, which is required to lead the C315 sheathing canal. 2.Putting C315 sheathing canal into heart along with guiding wires. 3.Locating the C315 sheathing canal, and adjusting the head of C315 towards ideal pacing location. 3.Implanting the spiral electrodes and fixing them. Leading the spiral electrode to the side of his bundle along the C315 canal under the X-ray. The other electrode is leaded to right atrium like dual chamber pacemaker under the X-ray. 4.Revolving the 3830 electrode suitably to Immobilizing it in cardiac muscle. If the electrode can get his electric potential and produce his bundle pacing successfully, we revolve the 3830 electrode and immobilize it.
