Prevalencia de la fibrilación auricular en pacientes sometidos a cirugía cardiovascular en el Hospital Teodoro Maldonado Carbo en el periodo 2018 - 2019.

Abstract

Atrial fibrillation AF is a supraventricular arrhythmia that lasts more than 30 seconds, with replacement of P waves by fibrillation waves that can vary in amplitude, duration, and is generally associated with irregular RR intervals. There are studies that indicate that this disorder appears after any cardiac surgery, so its prevalence would be in a range of 25 to 40%, but there are also studies that indicate that this percentage would be in valve or mixed surgeries. In the HTMC, cardiac surgeries and interventional procedures have been performed, both revascularization and valvular or mixed. A study has not been conducted that allows us to know the prevalence of AF in patients undergoing this surgical procedure, nor has its associated risk factors been determined. Knowing this health problem would allow us to mark the indicators and perform their appropriate treatment. This study allows us to identify the type of cardiovascular surgery in which AF is more frequent as a complication and to characterize each of these patients. We will take into account that all patients undergoing surgery are older than 50 years of both sexes. The research is cross-sectional, retrospective, analytical, observational. They will be used for their descriptive and inferential statistical measurement and will be measured using the Excel program.
