Electrical remodeling of the atria in congestive heart failure: electrophysiological and electroanatomic mapping in humans.
BACKGROUND Atrial fibrillation (AF) frequently complicates congestive heart failure (CHF). However, the electrophysiological substrate for AF in humans with CHF remains unknown. We evaluated the electrophysiological and electroanatomic characteristics of the atria in patients with CHF. METHODS AND RESULTS Twenty-one patients (aged 53.7+/-13.6 years) with symptomatic CHF (left ventricular ejec...
متن کاملCONGESTIVE HEART FAILURE IN CHILDREN: A SURVEY OF 114 PATIENTS
During a period of four years between June, IS, 1988 to June, IS, 1992 one hundred and fourteen patients with congestive heart failure (CHF) were admitted to the pediatric department of Taleghani General Hospital. During the above period, 192 patients with heart disease were hospitalized at this department and CHF was the cause of admission in 59.4% of them. Congenital heart disease (CHO) w...
متن کاملIonic remodeling of cardiac Purkinje cells by congestive heart failure.
BACKGROUND Cardiac Purkinje cells (PCs) are important for the generation of triggered arrhythmias, particularly in association with abnormal repolarization. The effects of congestive heart failure (CHF) on the ionic properties of PCs are unknown. METHODS AND RESULTS PCs were isolated from false tendons of control dogs and dogs with ventricular tachypacing-induced CHF. CHF PCs were hypertrophi...
متن کاملPrecipitating factors of congestive heart failure in admitted patients of Fatemieh Hospital in Semnan, Iran
Introduction: Congestive Heart Failure (CHF) is a pathophysiologic state in which an abnormality of cardiac function is responsible for the failure of the heart to pump blood at a commensurate rate with the requirements of the metabolizing tissues and/or allows it to do so only from an abnormally elevated diastolic volume. In this study, the prevalence of precipitating factors of CHF in Semna...
متن کاملCongestive Heart Failure
The heart is composed of two independent pumping systems, one on the left side and one on the right. The right chamber, or right atrium, of the heart relaxes and expands to fill with blood that has returned from the body. (This relaxed action causes diastolic pressure, recorded as the second and lower number when measuring blood pressure). The used blood is poor in oxygen and rich in carbon dio...
