APPLIED PHYSICAL SCIENCES, MEDICAL SCIENCES Correction for ‘‘Synchronization of chaotic early afterdepolarizations in the genesis of cardiac arrhythmias,’’ by Daisuke Sato, Lai-Hua Xie, Ali A. Sovari, Diana X. Tran, Norishige Morita, Fagen Xie, Hrayr Karagueuzian, Alan Garfinkel, James N. Weiss, and Zhilin Qu, which appeared in issue 9, March 3, 2009, of Proc Natl Acad Sci USA (106:2983–2988; f...
Cardiac amyloidosis results in severely symptomatic heart failure that has a poor prognosis because of the development of a restrictive cardiomyopathy. The diagnosis of cardiac amyloidosis is often delayed because of nonspecific signs and symptoms. We report the case of a 66-year-old woman who had been diagnosed with sick sinus syndrome and presented 5 months later with a long QT interval and r...
Torsades de pointes (TdP)-an uncommon but life-threatening polymorphic ventricular tachycardia-is almost always drug induced. The authors describe the causes, risk factors, symptoms, diagnosis, and treatment of TdP.
The therapeutic efficacy of Atabrine in ventricular tachycardia has not yet been clearly demonstrated. In this case report, Atabrine stopped ventricular tachycardia and restored normal sinus rhythm following the fifth two-hourly oral dose of 0.30 Gm. Nausea and vomiting were the only toxic effects noted. Ventricular tachycardia, in this case, occurred as a complication of acute myocardial infar...
AIMS Comparing efficacy and safety of ibutilide vs. transoesophageal atrial pacing (ATP) for the termination of type I atrial flutter (AFL). METHODS AND RESULTS Eighty-seven patients affected by AFL lasting between 2 h and 30 days were randomized in two groups: Group 1-i.v. ibutilide treatment, up to 2 mg, and Group 2-ATP, with "burst" and "ramp" pacing protocols. Sinus rhythm was restored in...
A 27 year-old- lady was evaluated due to recurrent ventricular tachycardia. After performing echocardiography and cardiac MRI, she was found to have large pericardial cyst. Pathologic examination confirmed it as mesothelial pericardial cyst. Up to our knowledge it is the first presentation of simple pericardial cyst as ventricular a tachycardia.
Correspondence to: Dr Yee Guan Yap, Department of Cardiological Sciences, St George’s Hospital Medical School, Cranmer Terrace, London SW17 0RE, UK; [email protected] _________________________ I n 1966, Francois Dessertenne described a specific electrocardiographic form of polymorphic ventricular tachycardia, which he termed ‘‘torsades de pointes’’ (TdP). w2 The word ‘‘torsades’’ refers to an ornam...
