US Patent 9872628 Electrocardiogram systems and related methods

Embodiments disclosed herein are directed to electrocardiogram systems and systems of using electrocardiogram systems. The electrocardiogram systems are configured to detect at least two electrical potentials (e.g., a first electrical potential and a second electrical potential) at two or more surfaces of a subject (e.g., a first surface and a second surface). In an embodiment, the electrocardiogram system includes at least one position sensor configured to detect the position of the at least one electrode relative to a surface of the subject.
