Title: Cardiac Screening in Young Athletes
题目：年轻运动员的心脏检查
Author 作者: Semhar Tewelde

Sports are associated w/an increased risk for sudden cardiac death (SCD) in athletes who are affected by cardiovascular conditions predisposing to ventricular arrhythmias (VA)
运动对于一个有可以导致室性心律失常心血管疾病的运动员来说，将增加发生心脏骤停（SCD）的危险。
SCD has substantially decreased in Veneto Italy due to the introduction of a preparticipation screening program that identifies unrecognized cardiovascular conditions
SCD在意大利威尼托已明显下降，主要原因是实施了一个在参加运动前能够发现还没有诊断的心脏病的项目。
This study included 145 athletes evaluated for VA using a screening protocol of ECG, exercise testing, echocardiography, holter monitoring, and cardiac MRI
这一研究包括了145个运动员，通过ECG，运动试验，超声心动，动态心电监测，和心脏核磁来评价产生室性心律失常的可能性。
ECG was normal in most athletes (>85%)
多数运动员的心电图都正常（超过85）。
VA were detected prevalently during exercise testing 

室性心律失常主要发生在运动试验期间。
Cardiac MRI detected right ventricular regional kinetic abnormalities (ARVD) in 9 of 30 athletes 
心脏核磁在30个运动员中发现了9个有局部右室壁活动异常。
A total of 30% of these athletes had potentially dangerous VA
在这些运动员中，有30％有潜在的发生心室心律紊乱的危险。
In asymptomatic athletes w/prevalently normal ECG, most VA's can be identified by adding an exercise test 
对于心电图正常又无症状的运动员，多数心室心律紊乱可以通过心脏运动试验邋遢来诊断。
