Introduction Wellens’ syndrome is a pre-infarction electrocardiogram (ECG) pattern indicating critical proximal left anterior descending (LAD) stenosis and high risk of imminent acute myocardial infarction (MI). It is characterised by specific T-wave changes in precordial leads, typically biphasic or deeply inverted T-waves in V2–V3 (type B) or symmetrical deeply inverted T-waves in V1–V6 (type A).1 This pre-infarction state represents temporary stabilisation of an unstable coronary plaque.2 Current guidelines recommend urgent coronary angiography and revascularisation. However, for elderly patients with multiple comorbidities, invasive

Introduction The COVID-19 pandemic has posed a serious threat to global health worldwide. In an acute disease process, which is the case in COVID-19, electrocardiography (ECG) abnormalities are common, present in up to 93% of hospitalised critically ill patients.1 Any specific ECG alteration criteria could help emergency clinicians establish the prognosis and assess the risk of adverse events resulting from coronavirus infection. The purpose of this meta-analysis was to assess the prognostic value of the admission ECG (specifically: the duration of the PR interval, the QTc interval and the QRS complex and the heart rate [HR]) in COVID-19 pati

Introduction Implantable cardiac monitors (ICMs) are becoming more commonly recommended during the investigation of a patient with transient loss of consciousness.1,2 The original first-generation devices were implanted by a surgical procedure, usually by a cardiologist in a cardiac catheterisation theatre on a day-case basis, lasting up to 30–45 minutes per procedure. This process is inherently resource heavy for theatre time, staff (implanting physician, catheter lab nurses, cardiac radiographer and cardiac physiologist), in addition to pre-admission assessment, surgical equipment and patient recovery in a day-case facility.
