Electrocardiography patch

An apparatus, comprising:

• a patch, comprising:
• a strip with a first end section, a second end section opposite the first end section and a midsection, wherein the strip comprises a first surface and a second surface;
• adhesive covering a portion of the first surface;
• only two electrocardiographic electrodes comprising a first electrocardiographic electrode and a second electrocardiographic electrode, the first electrocardiographic electrode conductively exposed on the first surface along the first end section of the strip and the second electrocardiographic electrode conductively exposed on the second surface along the second end section of the strip;
• a flexible circuit mounted to the second surface of the strip and comprising a first circuit trace and a second circuit trace, the first circuit trace electrically coupled to the first electrocardiographic electrode, the second circuit trace electrically coupled to the second electrocardiographic electrode;
• a wireless transceiver affixed on the first end section;
• a receptacle on the strip;
• a battery housed by the receptacle;
• and
• memory operable to store samples of electrocardiographic signals;
• and
• a processor positioned over a portion of the flexible circuit on the first end section and electrically coupled to the first electrocardiographic electrode, the second electrode, the wireless transceiver, and memory.

An apparatus, comprising:

• a patch, comprising:
• a flexible backing including an elongated strip having a first end section, a second end section opposite the first end section, and a mid-section between the first end section and the second end section, wherein the strip tapers inward from both sides such that the mid-section has a portion narrower than widest portions of the first end section and the second end section, and wherein the strip has a first surface and a second surface, a portion of the first surface is covered in adhesive to adhere the strip to skin of a patient;
• a flexible circuit mounted to the second surface of the strip along the first end section and the second end section, the flexible circuit comprising a first circuit trace and a second circuit trace;
• only two electrocardiographic electrodes, the only two electrocardiographic electrodes being a first electrocardiographic electrode and a second electrocardiographic electrode, the first electrocardiographic electrode and the second electrocardiographic electrode coupled to and provided on the flexible circuit, the first electrocardiographic electrode conductively exposed on the first surface along the first end section of the strip, the second electrocardiographic electrode conductively exposed on the first surface along the second end section of the strip, the first circuit trace electrically coupled to the first electrocardiographic electrode, the second circuit trace electrically coupled to the second electrocardiographic electrode;
• a non-conductive receptacle mounted to the flexible circuit and overlying only one of the first end section or the second end section of the elongated strip;
• a battery received in the non-conductive receptacle such that the battery overlies the one of the first end section or the second end section;
• an electrical connector mounted to and electrically coupled to the flexible circuit, a portion of the electrical connector disposed between the flexible circuit and the battery, the battery in contact with the electrical connector;
• a wireless transceiver overlying the first end section;
• and
• a processor overlying a portion of the flexible circuit on the first end section, the processor electrically coupled to the first electrocardiographic electrode, the second electrocardiographic electrode, the wireless transceiver, and the battery, wherein the processor is configured to process electrocardiographic signals sensed via the electrocardiographic electrodes.
