BACKGROUND Atrial flutter not responding to medications could be secondary to structural malformations of heart. CASE CHARACTERISTICS A 5-year-old child with resistant arrhythmia, with onset in neonatal period. OBSERVATIONS Multiple right atrial diverticuli were detected on CT angiography and cardiac catheterization. Patient reverted to sinus rhythm following surgical excision of diverticul...

Persistent postoperative supraventricular tachycardia, despite adequate therapy, is a bad prognostic sign, and cardiac failure due to, or associated with, arrhythmia responds poorly to treatment. Of the 12 patients (24 per cent) resistent to therapy, eight developed congestive heart failure, with five dying as a result. The preoperative, intraoperative and postoperative factors contributing to ...

introduction: we report a 56-year-olds female with supraventricular arrhythmia due acute ischemic stroke without structural heart disease. case description: a patient presented with sudden onset of lethargy, right hemiplegia, and global aphasia. there was previous history of stroke 1 year ago presented with left hemiplegia that recovered completely during 10 days. there was no history of comorb...

Adenosine (Adenocard) is a unique new agent for the acute treatment of paroxysmal supraventricular tachycardia (PSVT). Administered by intravenous bolus, it has an onset and duration measured in seconds and greater than 90% efficacy. Its primary effect is to slow atrioventricular nodal conduction, thus converting reentrant forms of PSVT to normal sinus rhythm. Side effects quickly dissipate wit...

We have confirmed a supraventricular origin of bidirectional tachycardia with simultaneous standard electrocardiograms and a His bundle electrogram. The patient had sinus rhythm, variable trifascicular block and atrioventricular block below the His bundle. Ventricular excitation varied among three patterns which included right bundle branch block with right axis deviation (RBBB-RAD), right bund...

Atrial infarction is found in approximately 17 percent of autopsy-proven cases of myocardial infarction, but is a frequently missed clinical diagnosis. The antemortem diagnosis of atrial infarction occurring in the absence of ventricular infarction has not been previously reported. We present a patient with ischemic chest discomfort associated with paroxysmal atrial fibrillation. Electrocardiog...

PURPOSE Cholinergic nerve plays an important role in the induction and maintenance of atrial fibrillation (AF). Cholinergic innervation at supraventricular tissues is considered to be the histological basis and intervention-associated target site for the arrhythmia; however, the distribution of cholinergic nerve in supraventricular tissues has not been clearly studied. In this study, we investi...
