Method of signal enhancement for ecg devices

A method of monitoring cardiac electrical activity, comprising:

• receiving one or more cardiac electrical signals from one or more ECG devices, wherein each of said one or more ECG devices comprises a pair of electrodes positioned on longitudinally opposing ends of said one or more ECG devices, wherein
• a first electrode of a first ECG device of the one or more ECG devices is positioned at a first location of either maximum or minimum electrical potential for a first predetermined ECG signal;
• and
• each of said one or more cardiac electrical signals represents a difference in an electrical potential between the first and a second electrode of the pair of electrodes;
• reviewing cardiac data based on said one or more cardiac electrical signals to identify a cardiac event, and
• recommending addition of a supplemental ECG device in a supplemental position if the cardiac data is determined to be inadequate for identifying the cardiac event, the supplemental ECG device comprising a supplemental pair of electrodes positioned on longitudinally opposing ends of said supplemental ECG device.
