introduction: prolongation of qt interval might result in dangerous cardiac arrhythmias, including torsades de pointes (tdp), consequently leading to syncope or death. a limited number of studies carried out in this respect to date have shown that qt interval might increase during pregnancy. on the other hand, it has been shown that each pregnancy might result in an increase in the risk of card...

introduction a sudden loss of consciousness followed by abnormal movements can be ictal or syncopal in origin. transient response by the brain to sudden decrease of blood flow may cause sudden loss of consciousness followed by abnormal movements that mimic seizure. dysrhythmia is one of the important and critical reasons of such events that should be differentiated from seizure. case presentati...

background: cirrhotic patients are at a greater risk of different kinds of arrhythmias. despite the well-known arrhythmogenic effects of halothane, developing countries continue to use halothane due to its low cost. this study was designed to investigate the pathophysiology of halothane untoward effects on heart rhythm moreover was aimed to explore the effect of halothane anesthesia on the thre...

Incidence and prognostic relevance of supraventricular arrhythmias were evaluated in nine studies. These studies investigated patients with different forms of pulmonary hypertension. Supraventricular arrhythmias were more often found in patients with group two pulmonary hypertension. Common findings in these patients were elevated right atrial pressure and diameters and reduced tricuspid annula...

abstract background prolonged p-wave duration and p-wave dispersion indicate interatrial conduction disturbance and early predict arrhythmia especially atrial fibrillation. iron deposition in the atrial tissue might prolonged the atrial conduction time, and this study evaluated the p-wave prolongation and increased p-wave dispersion in these patients. materials and methods fifty patients with m...

background: cardiac failure is the major lethal consequence of aluminum phosphide (alp) poisoning. this study was designed to determine the frequency of cardiac arrhythmias in patients with alp poisoning. methods: in this prospective cross-sectional study, patients with definitive history of alp poisoning treated at emergency department of allied hospital faisalabad, faisalabad, pakistan, from ...

objective: to determine the type and pattern of arrhythmic events following the 2012 ahar-varzegan earthquake among patients implanted with cardiac defibrillators (icds) in east azarbaijan province. methods: in a prospective cohort study, conducted in east azerbaijan province of iran, 132 patients were enrolled in two comparison groups according to the region of residence i.e., earthquake regio...

flecainide has been known to cause torsades de pointes (tdp) in patients with structural heart disease and its mechanism has been attributed to use-dependency. we present a patient with flecainide-induced tdp in the absence of any other precipitating factors.this case highlights potential reverse use dependence associated with flecainide resulting in tdp.
