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; and
a controller configured to measure signals between said electrodes and to generate an ECG recording selected from the group consisting of standard lead traces and precordial traces when 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.

Abstract
An apparatus for generating ECG recordings and a method for using the same are disclosed. The apparatus includes a handheld device and a controller. The handheld device has first, second, third, and fourth electrodes on an outer surface of the handheld device. The controller records signals from the first, second, third, and fourth electrodes and generates an ECG recording from the signals. The controller also provides placement information regarding locations on a user'"'"'s body that are to be brought into contact with the first, second, third, and fourth electrodes while the controller records the signals. The handheld device can include a cellular telephone or a PDA. The controller stores an exemplary normal ECG recording, and compares a newly generated ECG recording with the stored ECG recording and generates an indication that indicates whether the newly generated ECG recording is consistent with the stored ECG recording.
