摘要 目的 应用多普勒组织成像 (DTI)技术检测三尖瓣环舒张期运动速度 ,结合三尖瓣血流频谱 ,评价高血压病右室舒张功能并探讨DTI的临床应用价值。方法  4 2例原发性高血压患者和 30例健康者 ,应用DTI测量三尖瓣瓣环舒张早期峰值速度 (e)、舒张晚期峰值速度 (a)。脉冲多普勒 (PW )测量二尖瓣口舒张早、晚期最大峰值速度Em、Am ,三尖瓣口舒张早、晚期最大峰值速度Et,At。结果 高血压组e/a、Em/Am、Et/A、e及Et较对照组减低 (P <0 0 1) ;高血压组a及At均高于对照组 (P <0 0 5 ) ,e/a与Et/At,Et/At与Em/Am间存在相关关系。结论 高血压引起右室舒张功能减低 ,且与左室舒张功能损伤有相关性。DTI技术可评价高血压右室舒张功能。
