This business plan studies the creation of a company for the monitoring of patients with cardiological diseases, located in the city of Mar del Plata, Argentina. At the same time, it includes an import analysis for the required devices and the planning of the implementation of the service, which includes a subscription for the rental of a smart watch and a portable electrocardiograph for personal use. The service is oriented to people in a critical or delicate cardiovascular condition with some of the most common pathologies in today's medicine: atrial fibrillation, heart failure and individuals who have suffered at least one acute myocardial infarction. Health centers in the city, including clinics, hospitals and cardiology centers, were taken as intermediaries who would "refer" patients to the company. This book implies an innovative approach to the use of cutting-edge technologies in today's cardiovascular medicine.
