In a retrospective study, the P-terminal force in Lead V1 (PTF-V1) was measured in three groups, each of 35 patients, with the respective diagnoses of acute myocardial infarction without pulmonary edema, acute pulmonary embolism, and acute pulmonary edema. In all but one of the patients with acute pulmonary edema, a highly negative PTF-V1 value was obtained, whereas by contrast, all the patients with pulmonary embolism had normal PTF-V1 values. Four of the patients with acute myocardial infarction had abnormal PTF-V1 values, although at the time there was no clinical or radiologic evidence of pulmonary edema. However, one of these patients did develop acute pulmonary edema a few hours later. Measurement of the PTF-V1 is a simple noninvasive test that may, therefore, be useful in separating patients with acute pulmonary embolism from those with acute or impending pulmonary edema.
在一项回顾性研究中，对三组患者（每组35例）进行了V1导联P波终末电势（PTF-V1）测量，这三组患者分别被诊断为无肺水肿的急性心肌梗死、急性肺栓塞和急性肺水肿。除1例急性肺水肿患者外，其余所有急性肺水肿患者均获得高度负性PTF-V1值，相比之下，所有肺栓塞患者的PTF-V1值均正常。4例急性心肌梗死患者的PTF-V1值异常，尽管当时尚无肺水肿的临床或影像学证据。然而，其中1例患者在数小时后确实发生了急性肺水肿。PTF-V1测量是一项简单的非侵入性检查，因此可能有助于区分急性肺栓塞患者与急性或即将发生肺水肿的患者。
