Abstract

An ambulatory electrocardiographic (ECG) monitor with a jumpered sensing electrode and method of use is provided. Self-powered ECG sensing circuitry is fully enclosed in a housing that provides electrode connection receptacles on a bottom surface of the housing. A flexible and stretchable electrode mounting panel having an elongated shape is provided with a layer of skin adhesive on a skin contacting surface. Sensing electrodes are mounted on opposite ends of the mounting panel. Each sensing electrode includes an electrode pad facing the skin contacting surface and an oppositely-facing electrode connection plug. Each connection plug is removably and pivotably couplable into the connection receptacles. A jumper wire assembly includes a jumper connection plug electrically connected to a jumper connection receptacle. The jumper connection plug is removably and pivotably couplable into the connection receptacles and the jumper connection receptacle is removably and pivotably couplable into the connection plugs on the mounting panel.
