Title: Loss of Precordial T-Wave Balance
题目：胸前导联T波异常
Author 作者: Semhar Tewelde
 
Typically the normal ECG shows progression of T-wave size across the precordial leads & the T-wave in V1 is inverted or flat
通常情况下，正常的心电图胸前导联T波应该是逐渐增高，V1的T波应倒置 或平坦
A large upright T-wave in V1 can be considered normal when there is high voltage/LVH or LBBB
当有高电压/左室肥厚或左束支传导阻滞时，V1导联大型直立T波可以认为 是正常的
A new upright T-wave in V1 can be indicative of significant atherosclerotic disease
一个新的在V1出现的直立T波，标志着动脉粥样硬化性疾病
If the T-wave in V1 is larger than the T-wave in V6 have a high suspicion for myocardial disease
如果V1T波大于V6T波，要高度怀疑心肌病
A new tall upright T-wave in V1 has ~84% specificity for ischemic heart disease (Barthwal)
在V1出现的一个新的高大直立T波具有〜84％的标志缺血性心脏疾病的特 异性（Barthwal）
