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 ...

Atrial fibrillation is a significant public health burden, with clinically, epidemiologically and economically significant repercussions. In the last decade, catheter ablation has provided an improvement in morbidity and quality of life, significantly reducing long-term healthcare costs and avoiding recurrences compared with drug therapy. Despite recent progress in techniques, current catheter ...

background: atrial fibrillation (af) is prevalent among cardiac patients; and as the risk of thromboembolism is high in this arrhythmia, discrimination of the effective risk factors in producing left atrial (la) thrombosis is clinically important. the molecular structure of lipoprotein(a) [lp(a)] is very similar to plasminogen , so it can be hypothesized that the high level of lp(a) is a compro...

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...

A 71-year-old male with known bronchiectasis and atrial fibrillation was admitted to Seoul St. Mary's Hospital with recurrent transient ischemic attack. Radiofrequency ablation was performed to resolve the patient's atrial fibrillation, but failed. However, a fistula between the left circumflex artery and the bilateral bronchial arteries was found on computed tomography. Fistula ligation and a ...

Left atrial thrombus in the presence of diseased mitral valve and atrial fibrillation is a well known entity. But it is very rare to occur in the presence of normal mitral valve apparatus. We report the case of a 36 year old female who presented with left atrial ball valve thrombus and normal mitral valve apparatus and underwent surgery. This patient with gangrene of right lower limb came for c...

INTRODUCTION: Left atrial ganglionated plexi ablation is an adjuvant technique used to increase the success rate of surgical ablation of atrial fibrillation. Ganglionated plexi ablation requires previous detection. We aimed to assess determinants of successful ganglionated plexi detection and to correlate range of ganglionated plexi ablation with risk of early atrial fibrillation recurrence. ...
