extracellular ca 2+ concentration ([ca2+]o) may be one of the factors affecting atrial natriuretic factor (anf) release. in the previous studies, there are opposite reports about the effect of [ca2+]o on anf secretion. therefore, the effect of [ca2+]o depletion on anf secretion and gene expression was studied in the present research. isolated right atria from rats were perfused for 6 and 2 hour...

introduction: atrial fibrillation (af) is the most prevalent cardiac arrhythmias that cardiologists and internists encounter. the goal of this article is to clarify an overview of the evidence linking inflammation to af existence, which may highlight the effect of some pharmacological agents that have genuine potential to reduce the clinical burden of af by modulating inflammatory pathways. mat...

results: the average of dyssynchrony in eight cycles showed a positive correlation with dyssynchrony in target beat rr1/rr2 = 1. average of dyssynchrony in target beat was 46.77 msec, and average of 8 cycle was = 47.701, (p value = 0.776, pearson linear correlation 0.769). objectives: we proposed to evaluate intraventricular mechanical dyssynchrony by measuring time-to-peak systolic velocity be...

background: atrial fibrillation (af) after coronary artery bypass graft (cabg) is a common complication with potentially higher risk of adverse outcome and prolonged hospital stay. objective: to determine the impact of postoperative af (poaf) on long-term outcome in a large cohort of patients who underwent cabg. patients and methods: we conducted an observational cohort study of 989 patients wh...

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 transferred to ...

Background: Psoriasis is a prevalent chronic T cell mediated inflammatory skin disorder. Recent studies have reported an increase in the incidence of arrhythmia in psoriasis patients who run an excessive risk of metabolic syndrome and cardiovascular diseases. P-wave dispersion (PWD) and duration are important electrocardiographic (ECG) markers employed to anticipate the risk of atrial arrhythmi...

a secundum atrial septal defect is the most common congenital heart defect. transcatheter treatment of secundum atrial septal defects is a popular and less invasive alternative to surgery. procedural complications may occur in a wide spectrum, particularly device embolus as the most emergent one, but luckily they do not commonly occur in the clinical setting. mortality from adverse events relat...

atrial dissociation is characterized by different types of p waves captured in an electrocardiogram, usually seen in critically ill or post-cardiac transplantation patients. our case demonstrates a 55-year-old man, presenting with chest pain (unstable angina) in the emergency department with transient double-p waves; representing the phenomenon. our case did not have any of the suggested causes...
