background: p wave dispersion (pwd) is defined as the difference between the maximum p wave duration (p max ) and the minimum p wave duration (p min ) 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 ...
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...
behcet’s disease is a rare immune mediated systemic vasculitis which besides it’s more frequent involvement of eyes and skin, sometimes present with aortic pseudo aneurysm and more rarely cardiac inflammatory masses.a 51-year-old patient with behçet’s disease presented with two symptomatic aortic pseudoaneurysms concomitant with a right atrial mass. computed tomography (ct) revealed one supra...
renal dysfunction is a risk marker in patients who candidate for coronary artery bypass graft (cabg). renal disorder is associated with prolonged stays in intensive care unit and hospital, morbidity and mortality. aim of this study is specific evaluation of association between preoperative creatinine (cr) with atrial fibrillation (af) after elective off-pump cabg in non-diabetic male patients w...
avnrt, (atrioventricular nodal reentry tachycardia), atrial tachycardia and atrial flutter are 3 kinds of supraventricular tachycardia, which their mechanism are explained based on reentry. a 60-years-old man is presented with all of the above-mentioned arrhythmias, responsive to intravenous injection of adenosine. radiofrequency ablation of the slow pathway territories cured all of them. there...
a 51-year-old man was admitted to the emergency department with palpitation and atypical chest pain. he had a history of percutaneous mitral valve commissurotomy 20 years previously. he did not use any drugs. physical examination was unremarkable except for a loud s1 on auscultation. the surface electrocardiogram (ecg) showed atrial fibrillation rhythmwith rapid ventricular response and right b...
Background: Asthma is a predisposing factor for the development of atrial fibrillation. Asthma disturbs the electrophysiology in the right and left atrium. The aim of this study was to evaluate atrial electromechanical delay by coupling obtained from tissue Doppler imaging (TDI) in children. Methods: A cross-sectional study was conducted on 50 patients with Bronchial Asthma, compared with 50 hea...
the use of diagnostic and therapeutic methods for assessing pulmonary vein due to its status as a main source of ectopic beats for the initiation of atrial dysrrythmias is strongly recommended. we report the case of a 13-year-old girl who was admitted to our hospital with the electrocardiogram manifestation of an ectopic atrial tachycardia. the focus of arrhythmia was inside the right upper p...
Holt-Oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. Skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. They range from clinodactyly, absent or digitalised thumb, hypoplastic...
