Anterior leads V3 and V4
ECG leads / veins · V3 V4
Precordial leads facing the anterior wall and apex; ST elevation here means LAD occlusion, with reciprocal depression in the inferior leads.
Traced from the start
Detail
- Territory
- Anterior LV wall and apex (LAD)
- Reciprocal change
- ST depression in II, III and aVF
When it goes wrong
ST elevation across V1 to V6 with I and aVL
Extensive anterior STEMI from a proximal LAD occlusion; highest risk of cardiogenic shock
Upsloping ST depression with tall symmetrical T waves in V1 to V6 (de Winter pattern)
A STEMI equivalent of acute LAD occlusion; activate the cath lab
