Abstract: Portable systems and methods for obtaining an electrocardiogram reading include a portable device having first and second electrodes with differing impedances. Computer instructions instruct a processor of the portable device to output instructional information relating to placement of the electrodes, receive confirmation of the positioning, and calculate lead values using readings from the first electrode, the second electrode, or combinations thereof, such that multiple bipolar and precordial leads can be measured. Augmented leads can be extrapolated using a known geometric relationship and the bipolar lead measurements. An electrocardiogram reading can be calculated from the lead measurements, then output, stored, transmitted, or combinations thereof. An alert response can be generated if the electrocardiogram reading deviates from selected threshold parameters.
