Defibrillators: Principles, Design, and Clinical Applications provides a comprehensive exploration of defibrillation in the prevention and treatment of sudden cardiac arrest. Covering cardiac electrophysiology, arrhythmia mechanisms, and shock delivery principles, the book also discusses the engineering design of external, implantable, and wearable defibrillators. It examines factors influencing defibrillation success, including waveform technology and timing, and highlights the role of artificial intelligence in modern devices. Regulatory, manufacturing, and safety considerations are integrated with clinical applications, making this work a valuable reference for biomedical engineers, clinicians, and researchers dedicated to advancing emergency cardiac care technologies.
