The electrocardiogram (ECG) is an extremely important diagnostic tool for the evaluation of electrical activity in the heart. The information helps identify functional abnormalities and to guide the decision-making process. In order to formulate an accurate idea about the health of the heart, it is critical that the provider have a comprehensive understanding of proper ECG lead placement. Failure to place electrodes at the appropriate locations can result in a non-standard result that makes it more difficult to diagnose and treat the patient.

Spatial Orientation and Einthoven’s Triangle

Electrical signals travel through the cardiac tissue along a complex network of nerves and intercellular connections. While signals pass through the heart, they can be detected by sensors that are placed on the patient’s body. Because these signals move along different spatial planes, the electrocardiogram must be capable of providing information about each plane. This is why there are standards for the number of electrodes … Click Here to Continue Reading
