We present a 74-year-old woman with kyphosis and symptoms of pre/syncope. Heart catheterization revealed dynamic left ventricular outflow tract obstruction (DLVOTO) with Brockenbrough Braunwald response only when kyphotic posture was assumed. She had a positive response to metoprolol. DLVOTO is a challenging diagnosis in the absence of resting LVOTO. ().
我们报告一名74岁患有脊柱后凸及晕厥前期/晕厥症状的女性。心脏导管检查显示，仅在采取脊柱后凸姿势时出现动态左心室流出道梗阻（DLVOTO）及布罗肯布罗夫-布劳纳尔德反应。她对美托洛尔有阳性反应。在无静息性左心室流出道梗阻的情况下，DLVOTO是一项具有挑战性的诊断。（）
