在开始心脏负荷测试前，做一些必要的准备，会让您的心脏负荷测试结果更加准确。
根据最近在克利夫兰诊所的心脏和血管团队发表的一项研究，通过下面的技巧可以很好的让您在运动平板上达到测试效果：
测试前一定要保持空腹，最好跳过一段饭。专家指出，测试者能够在空腹状态下测试更长的时间，并且测试过程的安全性更高。
测试期间要明确知道哪种药可以服用。心脏负荷测试的目的是用于评估心脏承受符合的能力，而有些药物会明显降低心率而影响测试结果。请咨询你的医生，明确哪些药是不能服用的。
不要喝咖啡。不要饮用清晨咖啡，避免服用含有咖啡因的非处方药。一些专家建议在测试前至少24小时避免咖啡因的摄入。
测试前要保持一定的运动量。特别是对于久坐不动的患者，需要每天有一定的运动。
管理好糖尿病指标，尽可能不要在糖尿病指标超标期间进行心脏负荷测试。
