Patients with right ventricular tachycardia may have adverse electrophysiological abnormalities linked to disturbed right ventricular structure. Seventeen patients who presented with right ventricular tachycardia without coronary artery disease or gross abnormalities of left ventricular function were studied. Patients had the ventricular tachycardia characterised at electrophysiological study a...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) has evolved from postmortem pathology at to a diagnosable clinical condition, and holds promise for definitive genetic diagnosis. Its prevalence is between 1/1,000 and 1/5,000, with 10% of deaths occurring before age 19 and 50% before age 35. When analyzed against age-specific norms, the electrocardiography (ECG) and signal-averaged ECG (SA...

Methods A total of 43 consecutive patients (age 44 10 years) with moderate to severe PVS referred to Royal Brompton Hospital from 2002 to 2005 were retrospectively studied. Patient New York Heart Association (NYHA) functional class was recorded. The RV (lateral tricuspid annulus motion) long-axis movement was measured by M-mode and pulsed-wave (PW) tissue Doppler imaging (TDI). Restrictive RV p...

Arrhythmogenic right ventricular dysplasia (ARVD) is a disorder in which normal myocardium is replaced by fibrofatty tissue. This disorder usually involves the right ventricle, but the left ventricle and septum also may be affected. Although the exact prevalence of ARVD is unknown, it is thought to occur in six per 10,000 persons in certain populations. After hypertrophic heart disease, it is t...

In pulmonary hypertension and other conditions, such as acute respiratory distress syndrome and left heart failure, right ventricular dysfunction is a prognostic determinant. Therefore, functional parameters pertaining to the right heart alone, i.e. independent of its loading conditions, should be used to quantify right ventricular disease progression and the results of treatment. Two methods t...

INTRODUCTION Right ventricular apical pacing-related heart failure is reported in some patients after long-term pacing. The exact mechanism is not yet clear but may be related to left ventricular dyssynchrony induced by right ventricular apical pacing. Right ventricular septal pacing is thought to deteriorate left ventricular function less frequently because of a more normal left ventricular ac...
