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.

15. A method for generating an ECG recording of a patient comprising:
-
providing a handheld device having first, second, third, and fourth electrodes on an outer surface of said handheld device; causing said patient to grip said handheld device such that said first and second electrodes are in contact with a first hand of said patient such that said first and second electrodes contact different locations on said first hand; simultaneously causing said patient to contact said third electrode with a predetermined location on said patient'"'"'s other hand; simultaneously causing said patient to contact said fourth electrode at a predetermined point on said patient'"'"'s body, said predetermined point depending on said ECG recording; measuring signals as a function of time between said first electrode and each of said second, third, and fourth electrodes; and converting said measured signals to said ECG recording. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method for measuring Precordial ECG signals from a patient, said method comprising:
-
placing a first electrode in contact with one of said patient'"'"'s hands; simultaneously placing a second electrode in contact with the other of said patient'"'"'s hands; simultaneously placing a third electrode in contact with a Precordial point on said patient'"'"'s chest; averaging signals from said first and second electrodes to provide an averaged signal; and measuring a potential difference between said averaged signal and a signal from said third electrode. - View Dependent Claims (23)
