Methodological differences in the placement of precordial ECG electrodes are a major problem in multicenter clinical trials and epidemiological studies. Trend analysis and realization of the full potential of computer programs for serial comparison demands reduction of technical sources of variation in the electrocardiogram (ECG) and vectorcardiogram (VCG) and particularly errors in locating ECG electrodes. The ECG electrodes locator described here reduces a major precordial uncertainty in the identification of the midclavicular and the anterior axillary lines. It simplifies positioning and provides a numeric record of the key precordial electrode positions, facilitating control of electrode placement errors in serial recordings.
心前区心电图电极放置的方法学差异是多中心临床试验和流行病学研究中的一个主要问题。趋势分析以及充分发挥计算机程序进行系列比较的全部潜力，要求减少心电图（ECG）和向量心电图（VCG）技术变异来源，尤其是心电图电极定位误差。本文所述的心电图电极定位器减少了确定锁骨中线和腋前线时心前区的主要不确定性。它简化了定位过程，并提供心前区关键电极位置的数字记录，便于控制系列记录中电极放置误差。
