基于心肌多普勒超声心动图，局部应变（S）和应变率（SR）可作为评价心室功能的局部参数。在临床儿科心脏病学中使用这些技术仍然是一个挑战。本研究建立了一个大的年龄范围内的健康儿童的收缩期和舒张期的S和SR的参考值，并评估了人口统计学和超声心动图参数对S和SR的潜在关系，特别是评估了健康儿童心率对S和SR的临床影响。结果表明，儿童生长期心率变化对收缩期、舒张期心肌收缩率和舒张晚期心肌收缩率均有重要影响，因此，评价儿童局部心肌功能时，应考虑静息心率。
Based on myocardial Doppler echocardiography, regional strain (S) and strain rate (SR) can be evaluated as regional parameters of ventricular function. The use of these techniques in clinical pediatric cardiology remains a challenge. This study establishes reference values for S and SR in both systole and diastole in healthy children over a large age range and evaluates the potential relationships of demographic and echocardiographic parameters on S and SR, and, in particular, assesses the clinical effect of heart rate on S and SR in healthy children. it is shown that heart rate changes in children during growth have an important impact on both systolic and diastolic myocardial S and late diastolic SR. Therefore, to evaluate regional myocardial function in children, heart rate at rest should be considered an important factor.
