Importance of geometry and refractory period in sustaining atrial fibrillation: testing the critical mass hypothesis.
BACKGROUND The critical mass hypothesis for atrial fibrillation (AF) was proposed in 1914. There has never been a systematic investigation defining the relationship between tissue geometry and AF. The purpose of this study was to determine the association among the probability of maintaining AF and the width, area, weight, effective refractory period (ERP), and wavelength in atrial tissue. ME...
متن کاملMedically Refractory Atrial Fibrillation
Background Pharmacological control of rapid ventricular response to atrial fibrillation may be difficult in some patients. Alternative treatments, including curative surgery or atrioventricular (AV) node ablation with pacemaker implantation, have significant potential morbidity. In view of evidence that dual AV nodal physiology may exist in a significant percentage of the population, even in th...
متن کاملIntravenous Methylprednisolone, a Possible Cause of the Atrial Fibrillation
We are presenting a case illustrating atrial fibrillation (AF) following the use of methylprednisolone in a patient with pelvic and femur fracture. A 48- year- old man with no significant past medical history, was admitted to the emergency department after injury in a car accident. He suffered a multiple bone fracture with chief complaints of pain and shortness of breath. He was transfer...
متن کاملMyocardial infarction and atrial fibrillation: importance of atrial ischemia.
BACKGROUND Myocardial infarction (MI) is associated with the development of atrial fibrillation (AF). We aimed to characterize the atrial abnormalities because of MI and determine the role of ischemia to the AF substrate. METHODS AND RESULTS Forty-four sheep were studied. MI was induced by occlusion of the left circumflex artery (LCX) or left anterior descending artery (LAD). Excluding 11 wit...
متن کاملMethods for determining the refractory period and excitable gap during persistent atrial fibrillation in the goat.
BACKGROUND Recently, the temporal excitable gap during atrial fibrillation (AF) has been identified as a vulnerable parameter for cardioversion of AF. In this study, we evaluated 5 methods to measure the refractory period (RP(AF)) and the excitable period (EP(AF)) during persistent AF. METHODS AND RESULTS In 11 goats instrumented with 83 epicardial atrial electrodes, persistent AF (43+/-34 da...
