title: [Classification of regular atrial tachycardia].
abstract: ECG criteria which for many years formed the basis of the classification of regular atrial tachycardias may now be completed by the results of endocavitary studies (stimulation and mapping). Flutter is a macroreentry phenomenon in the right atrium, anticlockwise in typical, common or classical forms, and more variable in atypical forms: sometimes antidromic and clockwise, sometimes functional more rapid without a gap of excitability, or in other cases, skirting around the sears of atriotomy, especially right-sided. Tachycardias are paroxysmal and often secondary to reentry; more rarely permanent, they are then often due to increased automaticity especially in young patients. The concordance with surface ECG changes is not perfect and the distinction between flutter and tachycardia often depends on the frequency of the tachycardia and the leads studied.
