Description
Technical Field
The invention belongs to medical equipment, relates to a special implantable physiological heart synchronous pacemaker for a Hipu system, and relates to a pacemaker capable of keeping heart synchronization or a resynchronization pacing treatment heart failure special implantable physiological heart synchronous pacemaker for the Hipu system.
Background
At present, a common double-cavity pacemaker and a three-cavity pacemaker exist, and the conventional double-cavity pacemaker is provided with two connecting holes which are respectively connected with an atrium hole and a right ventricle hole, so that the requirement of common double-cavity pacemaker (DDD) pacing treatment is met. Three-chamber pacemaker (CRT-P) ports are connected to the atrium, right ventricle and left ventricle respectively. Conventional dual chamber pacemaker right ventricular pacing, however, implants electrodes into the right ventricular apex or right ventricular septum, may cause asynchronous contraction of the heart, and pacemaker syndrome may occur in 3-20% of patients. CRT-P is an important apparatus for realizing heart resynchronization therapy in the market, is an important treatment means for realizing heart failure and QRS widening, and a left ventricular electrode is implanted into a coronary vein branch to perform double-chamber pacing, namely commonly used double-chamber pacing (BVP). BVP can partially correct heart failure and complete Left Bundle Branch Block (LBBB) improves cardiac synchrony contraction with an unresponsive rate of about 30%.
Hippo System Pacing (HPCSP) is an effective physiological Pacing for developing faster concurrency in recent years including bundle Pacing (HBP) and Left Bundle Branch Pacing (LBBP) which has been proven by numerous documents to maintain and restore cardiac synchrony (see document 1: Zhang W, Huang J, Qi Y et al. cardiac arrhythmia therapy by bundle heart disease and bundle heart disease, Heart Rhythm R2019; 16: 1783. 20190. Hou X, Qi Z, Wang Y et al. Feasibility heart Rhythm and cardiac Rhythm synthesis of the same patent). Pacing-dependent patients may have improved left ventricular function and remodeling following insertion into the atrial orifice via the Hippe line electrode (see document 3: Ye Y, Zhang Z, Sheng X et al. Updrade to His bundle and working-dependent functions transferred for pump generator change: Feasibility and intermediate focus up. int J Cardiol 2018; 260:88-92. document 4: Shanp, Su L, Zhou X et al. Beneficial effects of sizing to His bundle and working in fibrous sheets with left dependent effect summary <50.Heart rhyme 2018; 15: 405. 412). However, some factory pacemakers are inconvenient to use in patients with atrial fibrillation pacing indications due to the inability to turn off Ventricular Safe Pacing (VSP) if implanted bundle pacing is required.
In patients with wide QRS, hupu system pacing has again been shown to correct the classic left bundle branch block, resynchronizing cardiac contraction improves myocardial remodeling. Cardiac function is resynchronized by correcting for complete left bundle branch block by inserting a his bundle (or left bundle branch region pacing) electrode into the left ventricular jack, with or without fusion with the right bundle branch itself to optimize cardiac synchronization. Thus, no physiological cardiac-synchronized pacemaker specific to the hupu system exists in either the synchronized pacing or resynchronized pacing machine types.
BVP or his alone cannot correct wide QRS for nonspecific ventricular block (IVCD). After the his bundle pacing participates in the cardiac resynchronization therapy (HOT-CRT) of BVP, QRS can be further narrowed, and cardiac function can be further improved; the three-cavity pacemaker in the current market has no special prospective pacemaker needle and only has a left chamber jack. Meanwhile, the electrode of the jack of the left chamber of the partial machine type in the current market cannot be used for sensing. Atrial (A) -IS-1, Left Ventricular (LV) -IS-1 or left ventricular (IS-IV) (conventionally not perceptible) if prepared for implantation of CRTP if itself sinus rhythm; right chamber electrode (RV) -IS-1 (perceptible); when an uncorrectable IVCD is encountered, the Vopu pacing and the left ventricular electrode are required to participate in a synchronization reaction, but the sensing problem of the Vocal his bundle is solved and the left ventricular jack cannot be used for sensing and is limited.
At present, no pacemaker capable of being used for common pacing and heart synchronization treatment exists in the market, and meanwhile, the left ventricle synchronization can be maintained in the Xipu pacing treatment, the left ventricle synchronization can be recovered in the Xipu special synchronization, and even if the Xipu electrode is connected with a left ventricle hole and the left ventricle electrode is connected with a right ventricle hole in the conventional CRTP, the left ventricle hole cannot be used for sensing after the machine is connected. Therefore, aiming at the fact that the clinical treatment effect of the conventional Hipu system for maintaining the cardiac synchronization pacing and resynchronization pacing treatment is obvious, the design of the special cardiac synchronization pacing for the Hipu system is very critical to optimally maintain and recover the response of the cardiac resynchronization pacing treatment, so that the treatment hope is brought to the prevention of pacemaker-mediated heart failure occurrence and heart failure combined QRS, and more convenience is provided for the wide application of the Hipu system pacing in pacing and synchronization pacing treatment.
