Three-chambered cardiac pacemaker with heart resynchronization function - Vietnam Registration 2402074ĐKLH/BYT-HTTB

These are the implanted cardiac resynchronization therapy (CRT: HF-T and HF-T QP) and the implanted cardiac resynchronization therapy (CRT-P: HF-T and HF-T QP). The cardiac resynchronization therapy (CRT) device is a part of the implanted cardiac resynchronization therapy system, which includes the CRT device and the signal transmission wires. The main function of the system is first to sense the intrinsic heart rate and second to provide low-energy electrical pacing, as well as to provide low-energy anti-tachycardia pacing when necessary to ensure a stable heart rate or to support the intrinsic heart rate when necessary. The CRT-P systems have all the functions mentioned and in addition provide permanent sensing and pacing of the left ventricle. Implantation of the cardiac resynchronization therapy device is a symptomatic treatment with the following objectives: •Sensing and recording the heart rate and automatically detecting slow and fast heartbeats (PMs and CRT-Ps) •Compensating for slow heart rate through atrial or ventricular or sequential atrioventricular pacing (AV) (PM and CRT-P) •Physiological pacing (LBB(A)P) by stimulating the conduction system (PM and CRT-P) •Terminating fast atrial tachycardia (AT/AF) through anti-tachycardia pacing (ATP) in the atrium (PMs and CRT-Ps) •Cardiac resynchronization through multi-site ventricular pacing or through physiological pacing (CRT-Ps, e.g., biventricular pacing)
