چکیده

A 55-year-old woman with dilated cardiomyopathy and rate-dependent left bundle branch block had a cardiac resynchronisation therapy (CRT) device implanted. During implantation, the maximum rate of left ventricular pressure rise (dP/dt(max)) was measured invasively. This case presents a description of the acute negative effect of a left bundle branch block on dP/dt(max), and the different effect of CRT on left ventricular haemodynamic function in the presence and absence of a left bundle branch block.

Upgrade from ICD to CRT-D: clinical and haemodynamic impact of biventricular pacing in a patient with acquired long QT syndrome

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 ...

BACKGROUND Cardiac resynchronization therapy (CRT) is a medical device to help cardiac synchronized contractility by electrical impulses. Improvement of symptoms and left ventricular systolic function, reducing hospital admissions and mortality in patients with moderate to severe heart failure are the main benefits of administration of cardiac resynchronization therapy. CASE REPORT In this ar...

H eart failure effects 1–2% of the population and accounts for approximately 5% of all medical admissions; despite the undoubted improvements in treatment over the past two decades, the outcome remains poor. One third of those patients admitted with decompensated heart failure die within one year of their first hospitalisation and up to 50% will be readmitted within the first six months after t...

Objective: To quantify long term effects of cardiac resynchronisation therapy (CRT) by biventricular pacing in patients with heart failure (HF). Methods: Regional changes in left ventricular (LV) contraction patterns effected by CRT in 19 patients with HF (12 with ischaemia; mean (SD) age 66 (9) years) with bundle branch block were examined by colour Doppler tissue velocity imaging (c-TVI). Tim...
