The approach to emergency medical situations is not theoretical and complex, but practical and concise, in the form of an algorithm for acute and sudden issues that a non-specialist physician may face in everyday clinical practice. It aims to provide immediate solutions and safely facilitate the transportation of the patient to a healthcare facility that meets the necessary conditions for hospitalization. In this direction, this book is considered to offer and provide knowledge to physicians, enabling them to act safely, both for themselves and for the patient. CONTENTS 1. Arrhythmias 2.
