近年，右胸导联心电图在诊断右室梗塞（RVM1）中的意义逐渐受到重视。本文研究了正常人右胸导联心电图的波形、振幅及体位和呼吸对它们的影响，为分析RVM1的心电图改变提供了有参考价值的信息。材料及方法一、观察对象 受检者51例，男性38例、女性13例，平均年龄39岁（19—77岁）。选择标准：1．年龄＞18岁，身高＞150cm；体型正常，胸廓无畸形；2．无心肺病史，体检心肺无异常发现；3．血压≤21.3/12kPa；4．未使用可影响心电图的任何药物，且餐后四小时常规12导联心电图正常；5．正位或正、侧位X线胸片正常。
In recent years, the right chest lead ECG in the diagnosis of right ventricular infarction (RVM1) significance of the gradual attention. In this paper, the normal right chest lead ECG waveform, amplitude and position and the impact of breathing on them, for the analysis of RVM1 ECG changes provide valuable information. Materials and methods First, the subjects were observed in 51 cases, 38 males and 13 females, mean age 39 years (19-77 years old). Selection criteria: 1. Age> 18 years old, height> 150cm; normal body size, no deformity of the thorax; No history of heart and lung disease, physical examination without abnormal heart and lung findings; 3. Blood pressure ≤ 21.3 / 12kPa; 4. Not use any drugs that can affect the ECG, and normal 12-lead electrocardiogram four hours after a meal normal; Positive or positive, lateral X-ray normal.
