title: [Ventricular tachycardia "in salvoes"].
abstract: The term of ventricular tachycardia "in salvoes" describes electrophysiographic appearances of several consecutive ectopic ventricular beats without interposition of sinus rhythm. This is an intermediate arrhythmic state between isolated ventricular extrasystoles and sustained ventricular tachycardia. The generally accepted definition of the term "sustained" implies a duration of over 30 seconds or poor haemodynamic tolerance. Strictly speaking, the term "salvoe" has no precise definition in cardiology. In the 1996 edition of the Petit Robert French dictionary, the term is defined as the simultaneous discharge of guns or successive blasts of canons. The Delaware medical dictionary does not provide a French definition of the term "salvoe". In practice, we use the term tachycardia in salvoes in the same meaning as ventricular tachycardia. Schematically, in clinical practice, two situations may be encountered. In the first case, salvoes of VT are recorded in apparently normal hearts; they are not life-threatening and, though often nearly asymptomatic, they may pose therapeutic problems. In the second case, the arrhythmia occurs in a diseased heart, with a low ejection fraction, in which the essential problem is the vital prognosis.
