Abstract
An 80-year-old patient, previously implanted for idiopathic sustained ventricular tachycardia with a Rivacor VR-T DX implantable cardioverter defibrillator (ICD Biotronik, Berlin, Germany), came to our pacemaker clinic for palpitations. Electrocardiogram (ECG) showed sinus bradycardia with interpolated ventricular ectopic beats. A ventricular-paced event occurred with a coupling interval shorter than the expected one suggesting ventricular undersensing. The phenomenon can be explained by the default ICD sensitivity setting proposed by the manufacturer.
期刊介绍：
Pacing and Clinical Electrophysiology (PACE) is the foremost peer-reviewed journal in the field of pacing and implantable cardioversion defibrillation, publishing over 50% of all English language articles in its field, featuring original, review, and didactic papers, and case reports related to daily practice. Articles also include editorials, book reviews, Musings on humane topics relevant to medical practice, electrophysiology (EP) rounds, device rounds, and information concerning the quality of devices used in the practice of the specialty.
