Miniature ECG data acquisition device
First Claim
1. An apparatus comprising:
- a handheld device having first, second, third, and fourth electrodes on an outer surface of said handheld device, said handheld device having an extended configuration and a storage configuration;
a controller that measures signals between said electrodes and provides said signals to another device to generate an ECG recording selected from the group consisting of standard lead traces and precordial traces when said handheld device is in said extended configuration and said first and second electrodes contact a first hand of a patient such that said first and second electrodes contact different locations on said first hand, said third electrode being in contact with a location on said patient'"'"'s other hand and said fourth electrode contacts a point on said patient'"'"'s body chosen from the group consisting of said patient'"'"'s lower abdomen, one of said patient'"'"'s legs, and a precordial measurement point on said patient, said point depending on said ECG recording; and
a circuit that generates a common mode cancellation signal from signals on said second, third, and fourth electrodes and couples said common mode cancellation signal to said first electrode during said signal measurements.

Abstract
An apparatus for generating ECG recordings and a method for using the same are disclosed. The apparatus includes a handheld device having four electrodes on an outer surface thereof, the handheld device having an extended configuration and a storage configuration. The apparatus also includes a controller configured to measure signals between the electrodes to provide signals that are used to generate an ECG recording selected from the group consisting of standard lead traces and precordial traces. When the handheld device is in the extended configuration and the first and second electrodes contact a first hand of a patient such that the first and second electrodes contact different locations on the first hand, the third electrode is in contact with a location on the patient'"'"'s other hand and the fourth electrode contacts a point on the patient'"'"'s body that depends on the particular trace being measured.
