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. |

1. A portable system for monitoring heart activity of a user, the system comprising:
a portable device comprising a processor, data storage, a transmitter, an input device, and an output device; a first electrode positioned on a first portion of the portable device, wherein the first electrode comprises a first impedance; a second electrode positioned on a second portion of the portable device, wherein the second electrode comprises a second impedance configured to cause the second electrode to selectively perform as an indifferent electrode and one or more of a positive electrode or a negative electrode; non-transitory computer instructions for instructing the processor to receive a reading from the first electrode, receive a reading from the second electrode, calculate a lead value using the reading from the first electrode, the reading from the second electrode, or combinations thereof, and store the lead value; non-transitory computer instructions for providing instructional information relating to positioning of the first electrode and the second electrode using the output device and receiving confirmation of the positioning of the first electrode and the second electrode from the input device; non-transitory computer instructions for calculating at least one extrapolated lead using a plurality of stored lead values; non-transitory computer instructions for calculating an electrocardiogram using the plurality of stored lead values and the at least one extrapolated lead for storage, transmission, or combinations thereof, transmitting the plurality of stored lead values and the at least one extrapolated lead for calculation of the electrocardiogram, or combinations thereof; and non-transitory computer instructions for outputting the electrocardiogram, information relating to the electrocardiogram, or combinations thereof using the output device. |
