Cost Implications of Using Different ECG Criteria for Screening Young Athletes in the United Kingdom

High false-positive rates and cost of additional investigations are an obstacle to electrocardiographic (ECG) screening of young athletes for cardiac disease. However, ECG screening costs have never been systematically assessed in a large cohort of athletes.

The use of gastrointestinal cocktail for excluding myocardial ischaemia in the emergency setting: A systematic review

Differentiating acute chest pain caused by myocardial ischaemia from other potentially more benign causes of chest pain is a frequent diagnostic challenge faced by Emergency Department clinicians. A systematic review of the literature was conducted to locate and evaluate clinical trials comparing the use of an oral “gastrointestinal (GI) cocktail” (oral viscous lidocaine /antacid ± anticholinergic) to standard diagnostic protocols (serial electrocardiograms (ECGs), serial biomarkers, imaging and/or provocative testing) to differentiate emergency patients presenting with acute chest pain caused by gastro-oesophageal disease from those with other aetiologies.

Effects of pre-hospital ECG transmission for ST-elevation myocardial infarction in Counties Manukau

In April 2013 the St John’s Ambulance Service began transmitting ECGs electronically to the Middlemore emergency department (MMH ED) to enable earlier catheter lab activation and out-of-hours bypass to Auckland City Hospital (ACH) for ST-elevation myocardial infarction (STEMI) patients. We assessed whether these changes further reduced time to primary PCI.

Spatial QRS-T angle following acute coronary syndromes

The ECG derived spatial QRS-T angle provides a measure of ventricular repolarisation abnormality, and enlarged QRS-T angle (greater than 100 degrees) has been correlated with increased mortality risk following acute coronary syndromes (ACS). In this study we examined the proportion of ACS patients with a greater than 100 degree QRS-T angle, and the effects of revascularisation following ACS on QRS-T angle.

Diagnostic accuracy of different electrocardiographic and radiographic criteria for left atrial enlargement as assessed by cardiac magnetic resonance

Presence of left atrial enlargement is a predictor of significant cardiovascular morbidity and mortality in various populations, particularly hypertensive patients. Although the electrocardiogram (ECG) and chest X-ray (CXR) are the standard tests in clinical practice, the diagnostic performance of these tests as compared to the promising gold standard for the diagnosis of left atrial enlargement (LAE), cardiac magnetic resonance (CMR) is not well evaluated. This study was sought to assess the accuracy of the ECG and CXR criteria to diagnose LAE determined by volumetric CMR.
