Twelve-lead portable heart monitor
First Claim
1. An apparatus for obtaining electrical heart activity of an individual in a form capable of producing a twelve-lead electrocardiogram of an individual, said apparatus including:
- a right arm electrode;
a left arm electrode;
at least one leg electrode;
a portable electrode support having at least seven precordial electrodes fixed thereon, said at least seven precordial electrodes extending laterally across the support so as to assume different lateral positions across a human chest when said support is positioned over the human chest; and
circuitry provided in electrically connected relation to said right arm electrode, said left arm electrode, said at least one leg electrode, and said precordial electrodes, said circuit being capable of selectively operating a selected six of said at least seven precordial electrodes at positions corresponding to six Wilson precordial leads for the individual, said circuitry being constructed and arranged to convert the electrical heart activity of the individual obtained by said electrodes into a form capable of producing a twelve-lead electrocardiogram.

Abstract
An apparatus for obtaining electrical heart activity of an individual in a form capable of producing a twelve-lead electrocardiogram of an individual, said apparatus including: a right arm electrode; a left arm electrode; at least one leg electrode; a portable electrode support having a plurality of at least seven precordial electrodes fixed thereon. The at least seven precordial electrodes extend laterally across the support so as to assume different lateral positions across the human chest when the support is positioned over the chest. Circuitry is carried by the support in electrically connected relation to the electrodes and is capable of selectively operating a selected six of the plurality of precordial electrodes at positions which correspond to the six Wilson precordial leads for the individual. The circuitry is constructed and arranged to convert the electrical heart activity of the individual obtained by the electrodes into a form capable of producing a twelve-lead electrocardiogram.

28. A method of obtaining electrical heart activity of an individual in a form capable of producing a twelve-lead electro-cardiogram of an individual comprising the steps of:
-
applying a right arm electrode, a left arm electrode, and a leg electrode to skin of the individual at locations which enable leads I, II, III, AVR, AVL and AVF to be obtained therefrom; engaging a plurality of at least seven precordial electrodes extending laterally across an electrode support with skin on the individual'"'"'s chest so that the precordial electrodes assume different lateral positions across the individual'"'"'s chest; operating the right arm electrode, left arm electrode and leg electrode; and operating a selected six of said plurality of precordial electrodes at positions corresponding to six Wilson precordial leads for the individual.
