Epiglottitis and torsade de pointes tachycardia.
نویسندگان
چکیده
Severe throat infection is not usually associated with a higher risk of paroxysmal attacks of torsade de pointes tachycardia. A patient is reported in whom epiglottitis was associated with the sudden development of cardiac syncope caused by an acquired adrenergic-dependent long QT syndrome and the development of ventricular arrhythmias.

"Torsade de pointes" tachycardia. Re-entry or focal activity.
Paroxysms of ventricular tachycardia in which the amplitude and the direction of QRS complexes change periodically are defined as "torsade de pointes" tachycardias. The mechanism of this atypical ventricular arrhythmia has not yet been elucidated. The aim of our study was to induce "torsade de pointes" tachycardia experimentally, in order to gain insight into its possible mechanism. The experim...
متن کاملTorsade de pointes tachycardia as a rare manifestation of acute enteroviral myocarditis.
A patient with cardiac arrest and documented torsade de pointes ventricular tachycardia is presented in whom acute coxsackievirus B2 myocarditis was identified as the most likely underlying cardiac condition. This case shows that torsade de pointes may occur as a rare manifestation of viral myocarditis. Serial serological tests and endomyocardial biopsies may be helpful in establishing a diagno...
متن کاملA practical approach to torsade de pointes.
The term torsade de pointes refers to polymorphic ventricular tachycardia that occurs in the setting of an abnormally long QT interval. While the most common cause is treatment with QT prolonging drugs, torsade de pointes also occurs in the congenital long QT syndromes and in the setting of acquired heart block or severe electrolyte disturbance, notably hypokalemia. Among QT prolonging drugs th...

The authors report an early occurrence (within 48 hours) of the newly described form of pause-dependent torsade de pointes following acute myocardial infarction. QT prolongtion after myocardial infarction a common ECG finding. Postextrasystolic QT prolongation rare but one of the warning signs for torsade de pointes ventricular tachycardia following myocardial infarction. Careful monitoring is ...
متن کاملTorsade de pointes: the clinical considerations.
Torsade de pointes is a form of polymorphic ventricular tachycardia occurring in a setting of prolonged QT interval on surface electrocardiogram. Congenital causes of prolonged QT interval occur in individuals with genetic mutations in genes that control expression of potassium and sodium channels and acquired causes are numerous, predominantly drugs causing prolonged QT interval by blockade of...
