Patent ID: 6973343

Claim:
A method for sensor placement for performing electrocardiographic recording of either the left or the right side of a human chest by means of a universal ECG multiple sensor dermal precordial mask for fitting four different sizes of human bodies including extra large, said mask incorporating sensor positions V 1 , V 2 , V 3 , V 4 , V 5 , and V 6 for left side recording, and VR 1 , VR 2 , VR 3 , VR 4 , VR 5 , and VR 6 for right side recording, said method comprising the steps of providing a mask having at least ten precordial sensor positions designated on said mask on opposite sides thereof with the V positions disposed on one side and the VR positions disposed on the other side and forming mirror images of each other, said V and VR positions each forming at least four sets of sensor groups including three alternate sensor positions for each of said V 5 and V 6 (VR 5 and VR 6 ) positions, wherein said ten sensor positions are disposed in a specific geometric arrangement with said V 1 -V 4 (VR 1 -VR 4 ) positions being utilized for all sizes of bodies, said V 5 (VR 5 ) position having two independent sensor positions and sharing two positions with said V 6 (VR 6 ) positions, and said V 6 (VR 6 ) position having two additional positions, said mask including indicia for determining which V 5 and V 6 (VR 5 and VR 6 ) sensor positions correspond to said four sensor groups, selecting which side of said mask corresponds to the side of the chest the ECG is intended to record, aligning said mask on a patient's chest so that said V 1 and V 2 (VR 1 and VR 2 ) positions are disposed approximately on opposite sides of the patient's sternum at the fourth intercostal space, ascertaining from said indicia which one of the four V 6 (VR 6 ) sensor positions provided by said mask lies on or is closest to the patient's midaxillary line, and utilizing for said recording the corresponding set of sensor positions which include the ascertained V 6 (VR 6 ) position.
