Pv_1终末电势(PTF—V_1)负值量的异常在诊断左房肥大或扩大中的价值,已受到普遍重视。本文试图以超声心动图(UCG)和x线检查为标准,与PTF—V_1负值量异常及二尖瓣P波阳性加以比较,并结合临床对PTF—V_1负值异常的动态观察来探讨Pv_1终末电势的临床意义。
The value of Pv_1 end-potential (PTF-V_1) negative value in the diagnosis of left atrium hypertrophy or enlargement has received widespread attention. This paper attempts to echocardiography (UCG) and x-ray examination as the standard, negative correlation with the negative PTF-V_1 and mitral P wave positive were compared, and combined with clinical dynamic changes of negative PTF-V_1 to explore the Pv_1 Clinical significance of terminal potential.
