When defining a 'new' arrhythmia it is reasonable electrocardiography or arrhythmias. If, however, to suppose that it may indeed have been recognized we turn to the French literature for authoritative many years previously. This applies to the disorder reviews (Brochier, Motte, and Fauchier, 1972; now called torsade de pointes, whose features have Slama et al., 1973; Puech, 1974), apparently obscure been so well worked out since it was characterized ventricular tachyarrhythmias that have proved by Dessertenne (1966, 1967).
