Cardiac resynchronisation therapy (CRT) is a widely-performed standard treatment for improving cardiac function and quality of life in patients with heart failure.1 After CRT, however, 30–40 % of patients do not experience improvements in left ventricular (LV) function and clinical symptoms.2–3 The key factors for increasing the response rate to CRT are identification of the optimal LV lead… View more

Since the introduction of CRT more than 20 years ago, its role in mild to severe systolic heart failure has become well established. CRT has been shown to decrease mortality, reduce heart failure hospitalisations and improve functional status in patients with NYHA class II–IV heart failure and QRS prolongation, most commonly with LBBB pattern.1 One of the major limitations of CRT implementation… View more

CRT is an essential treatment for patients with heart failure and reduced ejection fraction as it can restore left ventricular (LV) electrical and mechanical synchrony. It has been shown to increase quality of life, improve functional status, reduce hospitalisation, improve LV systolic function and reduce mortality in properly selected patients.1,2 While CRT is an effective therapy, approximately… View more

A Brief History of Cardiac Pacing Electrical stimulation of the heart was used sporadically throughout the 19th century, generating a set of case reports, largely related to attempts to resuscitate people.1 The contemporary field of cardiac pacing emerged in the 20th century (Figure 1). The first use of pacemakers in a modern sense was in the late 1920s when Australian anaesthetist Mark Lidwell… View more

Right ventricular apical pacing (RVAP) results in dyssynchronous ventricular activation that can lead to impairment of ventricular function. Alternative myocardial pacing sites such as RV septal pacing (RVSP) and RV outflow tract pacing still rely on myocardial cell-to-cell conduction and have not been shown to prevent pacing-induced cardiomyopathy.1 Biventricular pacing (BVP) certainly improves… View more
