Case Reports
The complete array of electrocardiogram abnormalities secondary to myocardial contusion in a single case.
Myocardial contusion is a complication of blunt thoracic injuries. Transthoracic echocardiography and electrocardiography (ECG) monitoring are important in suspected cases. We report a 54-year-old man, who sustained a number of injuries including blunt chest injury as a consequence of a road traffic accident. Electrocardiography monitoring over a 48 h period demonstrated sequential degrees of conduction system block coupled with a temporary cardio-version from persistent atrial fibrillation to sinus rhythm, suggesting coincident pulmonary vein contusion.

Clinical Trial
Response to intravenous ajmaline: a retrospective analysis of 677 ajmaline challenges.
The diagnostic type I ECG in Brugada syndrome (BS) is often concealed and fluctuates between the diagnostic and non-diagnostic pattern. Challenge with intravenous ajmaline is used to unmask the diagnostic Brugada ECG. The aim of this study was to evaluate the safety of the test and to identify predictors for the response to an intravenous ajmaline challenge. ⋯ Ajmaline challenge is a safe procedure to unmask the electrocardiographic pattern of BS. Electrocardiographic and clinical parameters were identified to predict patients' response to ajmaline. The results of this study guide the clinician in which setting an ajmaline challenge is an appropriate diagnostic step.

This study surveyed referring clinicians to identify barriers that may contribute to New Zealand's low national implantable cardioverter defibrillator (ICD) implant rate. ⋯ We have identified a number of potential barriers that will need to be addressed to raise the New Zealand ICD implantation rate.
