６例急性心肌梗塞病人，均为男性，年龄４３～６４岁。于急性心梗后６～８周，在步行训练的基础上，采用改良的Ｂｒｕｃｅ方案，心率限制法作低水平活动平板运动试验，以测定心功能容量。认为心率限制法安全可靠，比较实用。而心功能容量测定可以为每１例急性心肌梗塞病人提出个体化的活动动量及康复计划，更有针对性。必须严格掌握适应证，对没有心脏并发症的患者，可于病后３～４周作低水平运动试验，而对年迈及有心脏并发症者应该慎重。
Six patients with acute myocardial infarction, were male, aged 43 to 64 years. 6 to 8 weeks after acute MI, on the basis of walking training, a modified Bruce protocol and heart rate restriction method were used for low-level treadmill exercise test to determine the functional capacity of heart. Heart rate limit method that safe and reliable, more practical. The determination of cardiac function can be for each case of patients with acute myocardial infarction proposed individual momentum and rehabilitation activities, more targeted. Must be strictly controlled indications for patients without cardiac complications, can be 3 to 4 weeks after the disease for low-level exercise test, and those with heart and heart complications should be careful.
