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.
