1. A mobile, hand-held apparatus for automated cardiac electrical signal analysis, the apparatus comprising:
- a housing having a back, a first side, and a front, configured to be held by a patient'"'"'s hand against the patient'"'"'s chest;
a first electrode and a second electrode integrated on the back of the housing configured to measure bioelectric signals from the patient'"'"'s chest, wherein the first and second electrodes are positioned a distance of at least 5 cm apart;
a third electrode on the housing configured to measure bioelectric signals from the patient'"'"'s right hand;
a fourth electrode on the housing configured to measure bioelectric signals from the patient'"'"'s left hand;
a resistive network forming a central point in a sagittal plane through the patient'"'"'s chest passing between the third and fourth electrodes when the housing is held against the patient'"'"'s chest, wherein three orthogonal cardiac leads are formed from said electrodes and the central point; and
a processor within the housing configured to process the three orthogonal cardiac leads derived from the first, second, third and fourth electrodes.

Abstract
Methods and apparatuses, including devices and systems, for remote and detection and/or diagnosis of acute myocardial infarction (AMI). In particular, described herein are handheld devices having an electrode configuration capable of recording three orthogonal ECG lead signals in an orientation-specific manner, and transmitting these signals to a processor. The processor may be remote or local, and it may automatically or semi-automatically detect AMI, atrial fibrillation or other heart disorders based on the analyses of the deviation of the recorded 3 cardiac signals with respect to previously stored baseline recordings.
