The Stimuprat team is delighted to offer you this casebook on the interrogation and programming of Boston Scientific™ cardiac resynchronization therapy (CRT) devices. 35 clinical cases built from real LATITUDE™ recordings, in five chapters: LV pacing and threshold, LV impedance, sensing, keeping up the CRT, and bonus cases, including LBBAP. Two opening chapters cover the indications for CRT and the materials and preparation for the implant. Every case is also online in the interactive casebook, with its tracings, numbered explanations and animations.
