Assessment of left ventricular diastolic function in the critically ill patient remains a difficult issue in clinical practice. Combined use of routine transmitral and pulmonary venous Doppler patterns in conjunction with tissue Doppler imaging have been claimed to allow bedside diagnosis of diastolic dysfunction. Although in the previous issue of Critical Care it was clearly demonstrated there might be a difference in load dependency of the early myocardial tissue Doppler velocity between lateral and septal placed sample volume, there remain still several unanswered questions, particularly with respect to the preload dependency of these indices.
对危重症患者左心室舒张功能的评估在临床实践中仍然是一个难题。常规二尖瓣和肺静脉多普勒模式与组织多普勒成像联合使用，据称可实现舒张功能障碍的床旁诊断。尽管在上一期《重症监护》中已明确表明，位于外侧和间隔的取样容积处早期心肌组织多普勒速度的负荷依赖性可能存在差异，但仍有几个问题未得到解答，特别是这些指标的前负荷依赖性问题。
