Sensor Placement - Cardiac Monitoring
Triangle
The three sensors applied may be placed in a few different locations, but ultimately they form a "triangle" around the heart.
This often referred to as Einthoven's Triangle.
Locations
- One sensor is placed on either the right wrist, right deltoid or upper outer aspect of the chest, just inside the right shoulder.
- The next sensor is placed on either the left wrist, left deltoid or upper outer aspect of the chest, just inside the left shoulder.
- Finally, this last sensor is placed at either the inner left lower leg (just above the ankle) or at the left lateral costal margin of the ribs.
