Question

Which precordial electrode is placed in the fifth intercostal space, where it intersects an imaginary line drawn straight down the middle of the clavicle?

Answer 1

The precordial electrode placed in the fifth intercostal space, where it intersects an imaginary line drawn straight down the middle of the clavicle, is called V4.

Step-by-step explanation:

In a 12-lead ECG, the precordial electrode placed in the fifth intercostal space, where it intersects an imaginary line drawn straight down the middle of the clavicle, is called V4.

Here is the step-by-step explanation:

1. Locate the clavicle, which is the collarbone in the upper chest region.
2. Draw an imaginary line straight down the middle of the clavicle.
3. Identify the fifth intercostal space, which refers to the space between the fifth and sixth ribs.
4. Place the precordial electrode, specifically V4, in the fifth intercostal space where it intersects the imaginary line drawn down the middle of the clavicle.
