There is lack of evidence regarding the screening role of ECG for sudden cardiac death (SCD) prevention. Our aim was to evaluate the prevalence of ECG abnormalities among teenagers according to sport participation and competitive status.
Eleven thousand nine hundred and forty-nine Italian pupils from 179 secondary schools (13-19 years) were consecutively enrolled. ECG abnormalities were divided into minor and major. Medical history, clinical examination and sport activity information were acquired. Further evaluations were suggested in case of major ECG abnormalities. Follow-up was performed at 2 years.
N = 1945 (16%) pupils had ECG abnormalities. Major ECG abnormalities were detected in 13% of the cohort, minor in 34%. ECG abnormalities were more common in nonathletes compared with athletes. A diagnosis of cardiac disease was reached in 25 (1.6%) of the pupils with major ECG abnormalities.
ECG abnormalities are common among young populations and more prevalent in nonathletes. Among pupils with major ECG abnormalities 1.6% had a cardiac disease diagnosis. Our results are in line with the data supporting ECG screening in the general young population.
目前缺乏有关心电图（ECG）筛查在预防心源性猝死（SCD）中的作用的证据。我们旨在评估根据运动参与和竞技状态，青少年中 ECG 异常的发生率。
连续纳入了来自 179 所中学的 11949 名意大利学生（13-19 岁）。将 ECG 异常分为轻微和严重两种类型。获取了病史、临床检查和运动活动信息。如果存在严重的 ECG 异常，则建议进一步评估。随访时间为 2 年。
1945 名（16%）学生的心电图异常。队列中 13%的学生存在严重的 ECG 异常，34%的学生存在轻微的 ECG 异常。与运动员相比，非运动员的 ECG 异常更为常见。在存在严重 ECG 异常的学生中，有 25 人（1.6%）被诊断为心脏病。
心电图异常在年轻人群中很常见，在非运动员中更为常见。在存在严重 ECG 异常的学生中，有 1.6%的人患有心脏病。我们的结果与支持对一般年轻人群进行 ECG 筛查的数据一致。
