Cardiac Resynchronization Therapy Device Implantation (CRT-P/CRT-D)

This treatment is used for heart failure with intraventricular conduction delay, and can be either a pacing type (CRT-P) or a defibrillation type (CRT-D). Multiple electrodes are usually placed intravenously and positioned in the appropriate cardiac chamber or conduction area under fluoroscopic and electrical parameter guidance. If the coronary vein is not ideal, left bundle branch or His bundle pacing can be performed instead. The leads are connected to a pulse generator and implanted subcutaneously, with programming completed during the procedure. Postoperative monitoring includes heart rhythm, lead thresholds, and wound assessment. Follow-up includes ECG and ultrasound optimization to improve ventricular synchrony. The above is general health information, not medical advice; specific details are subject to specialist assessment and hospital protocols.
