having briefly touched upon the problem of terminology and classification of arrhythmias the authors consider the diagnosis and clinical evaluation of some disorders , including the extrasystole ( the significance of the extrasystolic interval ) , ectopic arrhythmias from the region of the atrio-ventricular junction ( with simultaneous consistent or transent disruption of the intraventricular conduction ) , isolated atrial tachycardia , some variants of auricular fibrillation , flutter paroxysms , paroxysms of ventricular tachycardia , with continued auricular fibrillation in particular , and also the earlier described electrocardiographic phenomenon tentatively interpreted as sinistroatrial fibrillation with dextraatrial tachycardia , as well as major types of disrupted condution .
