Where is V4 placement located?

Explanation:
V4 placement is at the left chest in the 5th intercostal space along the midclavicular line. This spot lines up with the apex of the heart, letting the lead capture electrical activity from the left ventricle. The 5th intercostal space is between the 5th and 6th ribs, and the midclavicular line runs down from the midpoint of the clavicle. Placing it higher (4th ICS) or lower (6th ICS) shifts the view away from the LV apex, and a midaxillary position would be too far lateral for V4 (those landmarks are used for V5/V6). So the correct location is 5th ICS, left midclavicular line.
