Article Synopsis
- Endless loop tachycardia (ELT) is a frequent issue in patients with implanted cardiac devices and can cause serious symptoms despite preventive measures.
- * A study analyzed 20 cases of sustained ELT from 4,520 device checkups over four years, finding it usually benign but occasionally harmful, particularly in patients with left ventricular dysfunction.
- * Various factors contributed to ELT, including improper AV synchrony and sensing issues, and adjustments like changing sensitivity settings or PVARP duration were necessary for management.
Newer devices incorporate advanced algorithms to have more accurate delivery of implantable cardioverter-defibrillator (ICD) therapy. Newer models of Abbott Implantable cardioverter-defibrillators like Gallant and Entrant have a new ventricular fibrillation (VF) therapy assurance algorithm. This algorithm has a proven role in avoiding under-detection of VF where some of the smaller electrograms are under-sensed.

A 63-year-old lady with a high-grade atrioventricular (AV) block and a structurally normal heart underwent permanent pacemaker implantation (dual chamber, Medtronic Ltd) 8 years back. On follow up, she had a recurrence of syncope after 3 years. The device interrogation at that time had revealed ventricular tachycardia (VT) for which she underwent implantable cardioverter defibrillator (ICD, Medtronic Ltd, Egida DR, DF1) upgradation at another center (electrograms not available).
