Role of Non-Invasive Imaging using Speckle Tracking Echocardiography in the Identification and Treatment of Patients At Risk of Arrhythmias and Consequent Sudden Cardiac Arrest

每年有15000名澳大利亚人死于心脏骤停。识别有风险的个体是一项重大挑战。我们将研究一种名为斑点追踪的心脏超声技术是否能让临床医生快速识别与心脏骤停相关的心肌变化。如果检测结果呈阳性，这项技术可能会广泛应用于大量人群，识别出处于危险中的个体，并有可能在心脏骤停发生之前将其拯救出来。

Every year, 15,000 Australians die from sudden cardiac arrest. Identifying individuals at risk is a major challenge. We will investigate whether a heart ultrasound technique called speckle tracking allows clinicians to rapidly identify changes in heart muscle that are associated with cardiac arrest. If found to be positive, the technique may be broadly applied to large populations, identifying at risk individuals, potentially rescuing them before cardiac arrest occurs.
