Verified step by step guidance

Understand the concept of Einthoven's triangle: Einthoven's triangle is an imaginary formation created by the placement of electrodes during an electrocardiogram (ECG). It is formed by the right arm, left arm, and left leg electrodes, creating a triangular shape on the body.

Recognize the anatomical location of the heart: The heart is located in the thoracic cavity, specifically within the mediastinum, and is positioned slightly to the left of the midline of the body.

Relate the heart's position to Einthoven's triangle: The heart lies within the boundaries of Einthoven's triangle because the triangle encompasses the chest area where the heart is located.

Clarify why the other options are incorrect: The heart is not superior, posterior, or lateral to Einthoven's triangle because the triangle is designed to include the heart's electrical activity within its boundaries for accurate ECG readings.

Conclude that the correct answer is: The heart is located within the boundaries of Einthoven's triangle, as this arrangement is essential for capturing the heart's electrical signals during an ECG.
