title: Inappropriate management of self-terminating ventricular arrhythmias by implantable cardioverter defibrillators despite a specific reconfirmation algorithm: a report of two cases.
abstract: Algorithms that attempt to reconfirm the presence of an arrhythmia prior to definite treatment have been implemented in ICDs to prevent inappropriate shock therapy due to self-terminating ventricular arrhythmias. Nevertheless, in two patients, clinically inappropriate shocks were delivered after spontaneous conversion of the arrhythmia despite the use of a specific reconfirmation algorithm. Reconfirmation criteria were met due to a premature ventricular complex causing a short cycle in the first patient and a long postextrasystolic pause in the second patient. To avoid inappropriate shock therapy due to self-terminating ventricular arrhythmias, further improvement of detection algorithms is required.
