Randomized controlled study of detection enhancements versus rate-only detection to prevent inappropriate therapy in a dual-chamber implantable cardioverter-defibrillator

2015 HRS/EHRA/APHRS/SOLAECE expert consensus statement on optimal implantable cardioverter-defibrillator programming and testing

“…The annual rate of inappropriate shocks has fallen dramatically from 37%-50% for SVT alone in early studies to 1%-5% for all causes in modern clinical trials [97,118,[126][127][128]. This decrease is likely due to differences in both clinical populations and the programming of multiple ICD parameters, including longer detection time and higher rate cutoffs.…”

Inappropriate ICD Shocks in Pediatric and Congenital Heart Disease Patients

“…However, the use of discriminators has been shown to decrease the rate of inappropriate shocks without compromising appropriate therapy or increasing mortality as compared with rate-only programming. 74,75 Nevertheless, relative to other programming parameters, there are fewer studies that directly evaluate the safety and reliability of discriminators, and the variety and heterogeneity of these parameters makes it difficult to determine their optimal use in clinical management.…”

Overview of implantable cardioverter defibrillator and cardiac resynchronisation therapy in heart failure management

“…Some reports suggested that the dual-chamber ICD provided clinical benefits in arrhythmia differentiation, prevention of inappropriate ICD therapy and patients who required pacing for bradyarrhythmias. (25)(26)(27)(28)(29) However, Dewland et al pointed out that complications were more frequent during the implantation of dual-versus single-chamber ICDs (3.17% vs. 2.11%; p < 0.001), with a higher in-hospital mortality (0.40% vs. 0.23%; p < 0.001). (24) Taking into account existing best evidence, American and European guidelines (19,30) …”
