Zusammenfassung

In diesem Beitrag berichten wir über zwei Patientinnen mit hochgradig eingeschränkter systolischer linksventrikulärer (LV) Funktion, intrinsischem komplettem Linksschenkelblock, Herzinsuffizienzsymptomatik (NYHA III) und implantiertem primärprophylaktischem 1-Kammer-ICD mit VDD-Sonde. Bei Sinusrhythmus mit erhaltener Chronotropie und gutem atrialem Sensing wird die Indikation zur Systemaufrüstung auf eine kardiale Resynchronisation (CRT) mit Verwendung der VDD-Sonde gestellt. Nach problemloser Implantation der LV-Sonden können stabile Messwerte mit hohem biventrikulärem Stimulationsanteil erzielt werden. Die Kasuistiken zeigen, dass in selektierten Patienten die Verwendung einer VDD-Elektrode zur kardialen Resynchronisation möglich ist.

Abstract

In this article the cases of two female patients with heart failure (functional class III) and an intrinsic complete left bundle branch block are reported. Both patients have had an implanted cardioverter defibrillator (ICD) connected to a VDD lead for primary prevention of sudden cardiac death. Atrial sensing was good/acceptable with a physiological frequency histogram and normal PQ time. A system upgrade to cardiac resynchronization therapy device (CRT) was planned. The VDD lead was directly connected to the Bivent ICD. The follow up showed stable measurements and a high biventricular pacing rate. Thus, usage of VDD leads for atrial sensing in CRT seems to be possible in a selected patient population.
