An apparatus for measuring cardiac electric activity of a patient includes a tubular structure embodied in a lightweight, gently u-shaped form factor. The tubular structure includes: a center portion, a left handle in an upright end of the tubular structure, a right handle in a contralateral upright end; a connector positioned in the center portion; first and second receiving electrodes in the right and left handles; and an efferent cable for coupling the connector with a processor for electronically inverting signals obtained from the electrodes to produce vectors enabling a calculation of a conventional twelve-lead electrocardiogram. The processor is operatively coupled with a fourth electrode affixed to the patient's ear.
