Transesophageal M-mode echocardiography was applied for the evaluation of left ventricular performance in a case of severe tetanus with labile hypertension due to sympathetic nervous 'storm'. When systemic blood pressure was elevated, increases in pulmonary arterial pressure, cardiac output, left ventricular enddiastolic diameter, fractional shortening and mean velocity of circumferential fiber shortening were noted. No changes were found in total peripheral vascular resistance or left ventricular endsystolic diameter. Positive pressure ventilation, rendered standard transthoracic echocardiography ineffective.
经食管M型超声心动图被用于评估一例因交感神经“风暴”导致血压波动的重症破伤风患者的左心室功能。当体循环血压升高时，肺动脉压、心输出量、左心室舒张末期内径、缩短分数和圆周纤维缩短平均速度均增加。总外周血管阻力和左心室收缩末期内径无变化。正压通气使标准经胸超声心动图检查无效。
