Clinical Significance of P Wave Dispersion in Prediction of Atrial Fibrillation in Patients with Acute Myocardial Infarction
Background: P wave dispersion (PWD) is defined as the difference between the maximum P wave duration (Pmax) and the minimum P wave duration (Pmin) in 12-leads of the surface electrocardiography. The aim of this study was to evaluate the values of PWD during atrial fibrillation (AF) after acute myocardial infarction (AMI). Methods: We prospectively evaluated atrial rhythms of 350 patients (251 m...
متن کاملDispersion of atrial repolarization in patients with paroxysmal atrial fibrillation.
UNLABELLED To study the role of the dispersion of atrial repolarization (DAR) in the genesis of atrial fibrillation (AF), monophasic action potentials (MAP) were recorded simultaneously from a catheter at the high lateral right atrium (HLRA) and a catheter moving around the high, middle and low lateral right atrium (RA) the high, anterior and posterior septal RA and the RA appendage in 15 patie...
متن کاملRole of atrial electrophysiology and autonomic nervous system in patients with supraventricular tachycardia and paroxysmal atrial fibrillation.
OBJECTIVES The purposes of this study were to evaluate the atrial electrophysiology and autonomic nervous system in patients who had paroxysmal supraventricular tachycardia (PSVT) associated with paroxysmal atrial fibrillation (PAF). BACKGROUND PAF frequently appeared in patients with PSVT. However, the critical determinants for the occurrence of PAF were not clear. METHODS This study popul...
متن کاملParoxysmal Atrial Fibrillation Prediction Using Isolated Premature Atrial Events and Paroxysmal Atrial Tachycardia
A simplified predictor of episodes of paroxysmal atrial fibrillation (PAF) is presented. Over a thirty minute monitoring time, the number of premature atrial complexes (PAC) without normal sinus node reset is counted. When the number of such PACs changes by more than 2 over the monitoring period, a PAF prediction is made. The PAC test is supplemented with a paroxysmal atrial tachycardia (PAT) t...
متن کاملCase report Cardiac amyloidosis presenting with paroxysmal atrial fibrillation
Amyloidosis is a rare disease with an incidence of approximately 6–10 cases per million person years. It is defined as tissue deposition of fibrils consisting of different types and weight of normal serum proteins’ subunits. Amyloidosis disease can involve different organs depending on the subtype. Amyloidosis frequently affects the heart, kidneys, gastrointestinal organs and nervous system. Am...
