我们描述了在心脏骤停和心肺复苏期间使用经食道回声多普勒观察的一系列研究。在未经治疗的室颤的最初7分钟内，左心房持续有规律的收缩。心前区加压和松弛后，室腔变形和二尖瓣关闭和开放。根据左心室舒张期和收缩期面积的差值计算的每搏量可以预测复苏的成功。左心室顺应性的进行性下降与左心室舒张期和每搏量的减少相关，并进展为结石心脏。
We describe a series of investigations that used transesophageal echo-Doppler observations during cardiac arrest and cardiopulmonary resuscitation. Regular contractions of the left atrium persisted during the initial 7 mins of untreated ventricular fibrillation. Ventricular chamber deformation and mitral valve closing and opening followed precordial compression and relaxation. Stroke volumes computed from differences between diastolic and systolic areas of the left ventricle were predictive of the success of the resuscitation. Progressive decreases in left ventricular compliance were associated with decreases in left ventricular diastolic and stroke volumes and progressed to a stone heart.
