A journal article was reviewed that contained information regarding the prognostic significance of left ventricular (lv) global function index (lvgfi) in patients with implantable cardioverter defibrillators (icd).The article reports patients who experienced inappropriate therapies which were defined as anti-tachycardia pacing (atp) or shock therapies in the case of a supraventricular arrhythmia (atrial fibrillation, atrial flutter, atrioventricular nodal reentry tachycardia (avnrt), atrioventricular reentrant tachycardia (avrt), sinus tachycardia, focal atrial tachycardia) or an oversensing due to lead issues or due to electromagnetic interferences.The status/disposition of the devices and leads is unknown.No further patient complications have been reported as a result of thisevent.
