Premature ventricular beats
Ventricular tachycardia (VT)
Monomorphic VT
Very rapid monomorphic VT (ventricular flutter)
Polymorphic VT
Ventricular fibrillation (VF)

Implantable cardioverter defibrillators (ICD)
????? ?? ???? ??.
Implantable cardioverter defibrillator (ICD) and therapies for ventricular arrhythmias. A. A monomorphic ventricular tachycardia (VT) is terminated by a burst of pacing impulses at a rate faster than VT (anti-tachycardia pacing). B. A rapid VT is converted with a high voltage shock (arrow). The chest x-ray in Panel C shows the components of an ICD capable of biventricular pacing. ICD generator in the subcutaneous tissue of the lex upper chest, pacing leads in the right atrium and the LV branch of the coronary sinus (LV lead) and a pacing/defibrillating lead in the right ventricle (RV lead) are shown.
