as a result of these limitations major arrhythmias both at atrial level ( salvos of extrasystoles , atrial tachycardia , flutter , fibrillation ) and junctional ( paroxysmal reciprocating tachycardia ) and ventricular levels ( ventricular tachycardias of differing origins and types ) are systematically disregarded by quantitative standardised protocols , although modern antiarrhythmic agents have been introduced precisely for their treatment .
