Women had similar rates of anticoagulation and similar time in therapeutic range. Women had lower (more severe) unadjusted baseline overall Atrial Fibrillation Effects on Quality of Life scores (n = 2007 80 IQR, 62-92 vs 83 IQR, 69-94 P < .001). Only 32.1% of women (n = 1378) were asymptomatic (European Heart Rhythm Association class I) compared with 42.5% of men (n = 2483) in unadjusted analyses ( P < .001). Compared with men, women were older (77 years interquartile range, 69-83, vs 73 years IQR, 65-80 P < .001) and had higher median CHA 2DS 2-VASc scores (5 IQR, 4-6, vs 3 IQR, 2-5 P < .001), but less sleep apnea (578 vs 1264 P < .001). Results Overall, 4293 of the cohort (42%) were female. Main Outcomes and Measures Symptoms, quality of life as measured by Atrial Fibrillation Effects on Quality of Life scores, AF treatment, cardiovascular outcomes, stroke or non–central nervous system embolism, and all-cause mortality. The Outcomes Registry for Better Informed Treatment of Atrial Fibrillation is a prospective, nationwide, multicenter outpatient registry of patients with incident and prevalent AF enrolled at 176 sites between June 2010 and August 2011. Objective To determine whether symptoms, quality of life, treatment, and outcomes differ between women and men with AF.ĭesign, Setting, and Participants This observational cohort study included 10 135 patients with AF. Importance Despite the frequency of atrial fibrillation (AF) in clinical practice, relatively little is known about sex differences in symptoms and quality of life and how they may affect treatment and outcomes.

Challenges in Clinical Electrocardiography.

This review was undertaken for that purpose showing the main features of pacemaker functioning, as well as, the correct interpretation of electrocardiographic traces and the main causes of malfunction. Doctors must be familiar with these findings and have an understanding of the main causes of malfunction. The electrocardiographic traces vary according to the type of device, number and location of electrodes, as well as their configuration. The use of stimulation has increased significantly from 46.7/100.000 in 1993 to 61.6/100.000 in 2009, showed by the dual chamber device use rate which has increased from 62 to 82% during this period, with around 20.000 upgrades performed yearly in the United States. Even more modern pacemakers are capable to provide diagnoses which indicate cardiovascular physiopathology. Several algorithms were designed to offer a time to deliver a stimulus pulse. The latest pacemakers have the ability to detect rhythm and provide cardiovascular disease states. With the development of pulse generators, pacemakers are now smaller in size and have increased device longevity and complexity. Es importante que el médico se encuentre familiarizado con estos hallazgos, así como las principales causas del mal funcionamiento, por ello se presenta esta revisión donde se muestran las características principales de función de los marcapasos, así como su normal interpretación en el electrocardiograma y las principales causas de mal funcionamiento.Ĭardiac pacemakers have been part of the therapeutic arsenal for the treatment of a variety of bradyarrhythmias during many decades. El trazado en el electrocardiograma varía de acuerdo con el tipo de dispositivo, número y colocación de electrodos, así como su configuración. El uso de la estimulación ha aumentado en forma significativa de 46,7/100.000 en 1993 a 61,6/100.000 en 2009, con el porcentaje de dispositivos de cámara doble, pasando del 62% al 82% durante este período, con alrededor de 20.000 reemplazos al año en los Estados Unidos.

Los más recientes ofrecen diagnósticos del ritmo y estado de la enfermedad, con varios algoritmos diseñados para ofrecer un tiempo de entrega de la estimulación de impulsos y aun los más recientes presentan diagnósticos indicativos de la fisiopatología. Los marcapasos cardíacos han sido parte del arsenal terapéutico para el manejo de una variedad de bradiarritmias durante muchas décadas y con la evolución de los generadores de estimulación se ha reducido su tamaño, incrementado la longevidad, así como su complejidad.
