Question

When performing electrocardiography, which of the chest leads should be placed at the 5th intercostal space at the junction of the left midclavicular line?

Answer 1

The V4 chest lead should be placed at the 5th intercostal space at the left midclavicular line when performing an electrocardiography.

Step-by-step explanation:

When performing electrocardiography, it's important to place the electrodes correctly to obtain an accurate ECG reading. In the case of the chest leads, the V4 lead should be positioned at the 5th intercostal space at the junction of the left midclavicular line. This placement is critical as each chest lead looks at a different part of the heart, and improper placement can result in inaccurate recordings of the heart's electrical activity.
