Long QT syndrome (LQTS) is characterised by
both the depolarisation and repolarisation disorder of
cardiac muscle cells. Cardiac resynchronising therapy
(CRT) is an important treatment option for patients with
chronic heart failure (CHF) when echocardiographic and
electrocardiographic criteria are met. Although CRT was
introduced in clinical practice 10 years ago, doubts related
to application of this treatment method persist because
of its potential proarrhythmogenic effect. This is a case
describing a 66-year-old Caucasian female with LQTS
coexisting with a left bundle branch branch block (LBBB)
and an implantable single-cavity cardioverter-defibrillator
(ICD VR), who had repeated appropriate high-energy
treatments. The upgrade to resynchronisation therapy
defibrillator (CRT-D) significantly reduced frequency of
ventricular tachycardia and the need for electrical therapies.
The normalisation of the left ventricle size, as seen
on echo examination, and the improvement of heart
failure symptoms were also observed.
