心悸原因揭秘：心肌灌注檢查結果解讀-心臟血管專科

心博過速？

---

何主任你好 我由於胸悶心跳過快急診抽血心電圖都沒什異常結果做了心肌灌注Under standardized dipyridamole stress test， (1) no significant inducible
ischemia in the myocardium， (2) adequate LV systolic function.
================================================================================

Study:
26025B Stress ＆ redistribution myocardial perfusion study with SPECT
(壓力與重分佈心肌斷層灌注掃描).
INDICATION: Diagnosis of coronary artery disease， R/O myocardial ischemia.
CLINICAL HISTORY: 43M. Chest tightness， tachycardia. Smoking. TET: Positive for
ischemia. UCG: Adequate LV systolic function (LVEF:57.9%)， No obvious regional
wall abnormality.
NUCLEAR MEDICINE STUDY: Thallium-201 myocardial perfusion imaging (MPI)，
dipyridamole ＆ resting.
RADIOPHARMACEUTICAL: Thallium-201 3 mCi intravenous.

SCINTIGRAPHIC FINDINGS:
Thallium-201 myocardial perfusion imaging was performed after standardized
dipyridamole stress protocol (dipyridamole: 0.56mg/Kg， continuous IV infusion in
4 minutes) and resting state， respectively.

The initial and 4-hour delayed images showed no definite perfusion defect in
the myocardium.

(1) Post-stress LVEF = 71%， rest LVEF = 79%.
(2) Wall motion: no obvious regional wall motion abnormality.

IMPRESSION:
Under standardized dipyridamole stress test， (1) no significant inducible
ischemia in the myocardium， (2) adequate LV systolic function.

Comment:
＞ The mean sensitivities and specificities of vasodilator SPECT for detecting
CAD (greater and equal 50% stenosis) are 86% and 73%， respectively.
(Reference: J Am檢查報告如上但我休息時還是心跳都在90-110醫生跟我說只要不要超過120都沒關係這是正常的嗎
