Hourly variability in outflow tract ectopy as a predictor of its site of origin.

Introduction: Before ablation, predicting the site of origin (SOO) of outflow tract ventricular arrhythmia (OTVA), can inform patient consent and facilitate appropriate procedural planning. We set out to determine if OTVA variability can accurately predict SOO.

Methods: Consecutive patients with a clear SOO identified at OTVA ablation had their prior 24-h ambulatory ECGs retrospectively analysed (derivation cohort).

Adalimumab for Crohn's disease in New Zealand--a prospective multicentre experience.

Aim: Adalimumab is an effective treatment for Crohn's disease (CD). We aimed to describe the early patterns of use, efficacy and response to adalimumab in four regions of New Zealand.

Methods: Prospectively collected CDAI data were used to examine adalimumab continuation rates in CD patients.
