在開始心臟負荷測試前，做一些必要的準備，會讓您的心臟負荷測試結果更加準確。

根據最近在克利夫蘭診所的心臟和血管團隊發表的一項研究，通過下面的技巧可以很好的讓您在運動平板上達到測試效果：

測試前一定要保持空腹，最好跳過一段飯。專家指出，測試者能夠在空腹狀態下測試更長的時間，并且測試過程的安全性更高。

測試期間要明確知道哪種藥可以服用。心臟負荷測試的目的是用于評估心臟承受符合的能力，而有些藥物會明顯降低心率而影響測試結果。請咨詢你的醫生，明確哪些藥是不能服用的。

不要喝咖啡。不要飲用清晨咖啡，避免服用含有咖啡因的非處方藥。一些專家建議在測試前至少24小時避免咖啡因的攝入。

測試前要保持一定的運動量。特別是對于久坐不動的患者，需要每天有一定的運動。

管理好糖尿病指標，盡可能不要在糖尿病指標超標期間進行心臟負荷測試。
