Universal electrocardiogram sensor positioning device and method
First Claim
1. A method for sensor placement of six precordial sensors, V1, V2, V3, V4, V5, and V6, typically used for performing twelve lead electrocardiograms, the steps comprisingproviding a universal ECG multiple sensor dermal chest mask formed for clinically efficacious placement of said six precordial sensors on a patient'"'"'s chest irrespective of torso size, said mask having at least nine sensors which are arranged in a specific geometric pattern which can be utilized to serve as sensors for at least three different classes of sizes of human torsos, said mask including first indicia for aligning said mask on both the centerline of the patient'"'"'s sternum and the fourth intercostal space, and second indicia for determining which of said sensors correspond to three choices for said V6 sensor, whereby at least three sets of sensors formed by said nine sensors on said mask comprising six sensors each accommodate three different classes of sizes of human torsos,placing said mask on a patient'"'"'s chest with said first indicia aligned with the corresponding anatomy of the patient,selecting one set of six of the nine sensors for performing an ECG from said second indicia depending upon which of said V6 sensors lies closest to said patient'"'"'s midaxillary line, andconnecting sensor lead wires from ECG test apparatus to said six selected sensors.

3. A method of sensor placement for performing twelve lead electrocardiograms by means of a universal ECG multiple sensor dermal chest mask formed for fitting or accommodating different sizes of adult human bodies with repeatability and clinical efficacy of sensors V1, V2, V3, V4, V5, and V6 placement irrespective of the varying human body torso sizes and the different distances between the human body anatomical landmarks, said method of sensor placement comprising the steps of
providing a mask having at least nine precordial sensors disposed in a specific geometric arrangement rather than in predetermined fixed arrays of individual sensor groups or an arbitrary individually located array of six precordial sensors needed for a resting ECG, said arrangement of nine sensors forming three sets of sensor groups including three positions for each of said V5 and V6 in which one sensor serves for either V5 or V6 in two different sensor sets whereby three sets of six sensors each are provided by said nine sensors to position six of said sensors proximate to the anatomical landmarks of three different classes of sizes of human torsos, said mask including first indicia for positioning said mask on a patient'"'"'s sternum centerline and the fourth intercostal space and second indicia for determining which sensors correspond to said three sensor sets, placing said mask on a patient'"'"'s chest and aligning said first positioning indicia on said mask with said patient'"'"'s corresponding anatomy, ascertaining from said second indicia which of the three V6 sensor positions lies on or closest to the patient'"'"'s midaxillary line, and connecting sensor lead wires from ECG test apparatus to the corresponding set of sensors which include said closest midaxillary V6 sensor.

4. A universal ECG multiple sensor dermal chest mask for fitting or accommodating different sizes of adult human bodies for performing twelve lead electrocardiograms with repeatability and clinical efficacy of sensor V1, V2, V3, V4, V5, and V6 placement irrespective of the varying human body torso sizes and the different distances between the human body anatomical landmarks, said mask comprising
a flexible sheet of non-conductive material carrying nine sensors in a single pattern rather than in predetermined fixed arrays of individual sensor groups or an arbitrary individually located array of six precordial sensors which are needed for a resting twelve-lead ECG, said sheet having said nine sensors positioned on said sheet in a specific geometric arrangement with said V1 -V4 being utilized for all sizes of bodies, said V5 position having two independent sensor positions and sharing a third with said V6, and said V6 having two additional positions whereby when said mask is utilized for a small size torso, the alternate V5 position closest to said V4 position is utilized along with said shared V5 and V6 position, when said mask is utilized for a medium size torso, the middle alternate V5 position, disposed between the first alternate V5 disposed closest to said V4 position, and between said shared V5 and V6 position, is utilized along with said V6 position disposed between said shared V5 and V6 position and the other remaining V6 position, and when said mask is utilized for a large size torso, said shared V5 and V6 position is utilized along with said remaining V6 position.
