The 5th edition of Cardiac Pacing and ICDs offers a clinically focused and detailed examination of the fundamentals, technical aspects and patient-centred applications of pacing systems and implantable cardioverter-defibrillators. The content begins with indications for permanent and temporary pacing and the basic principles of pacing technology, followed by haemodynamic considerations and the selection of pacing modes. Subsequent sections cover temporary pacing techniques, implantation and removal procedures, pacemaker timing cycles, the evaluation and management of system malfunctions, and the implantation and follow-up of ICDs, including troubleshooting. In addition, there is extensive coverage of cardiac resynchronisation therapy and clinical follow-up of patients with pacing systems, with case-based examples and practical approaches. The chapters are written by leading specialists and include illustrative figures and tables that clarify complex concepts.
