18. An adhesive patch device for synthesizing a 12-lead electrocardiogram (ECG), the device comprising:
a patch of adhesive material having a back and a front, wherein the back is configured to be adhesively secured to a patient's chest;
a first electrode and a second electrode integrated on the back of the patch 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 front of the patch and configured to measure bioelectric signals from the patient's right hand;
a fourth electrode on the front of the patch and configured to measure bioelectric signals from the patient's left hand;
a processor, within a housing of the patch, configured to derive three orthogonal cardiac leads from the first, second, third and fourth electrodes; and
a detection circuit configured to detect finger contact on both the third electrode and the fourth electrode, further wherein the processor is configured to collect the three orthogonal leads when the detection circuit detects the finger contact on both the third electrode and the fourth electrode.
