A method for performing ambulatory electrocardiographic monitoring on an adult female is provided. An ambulatory ECG monitor, that includes a plurality of sensing electrodes coupled to self-powered sensing circuitry, is provisioned. A monitoring site is located on the surface of a patient's chest at midline and above the body of the sternum adjacent to the fourth and fifth intercostal spaces between the breasts in the upper portion of the intermammary cleft. The electrodes are aligned and placed along the midline. Interference from breast tissue with placement of the ambulatory monitor at the monitoring site is evaluated. The ambulatory ECG monitor is removably adhered to the monitoring site clear of any breast tissue interference for the duration of monitoring. ECG data is sensed through the sensing electrodes at the monitoring site and the sensed ECG data is recorded into the sensing circuitry.

An electrocardiography patch is provided. A flexible backing is formed of an elongated strip of stretchable material and a pair of electrodes is respectively affixed on a contact surface of each end of the elongated strip. A flexible circuit is affixed on each end of the elongated strip and includes a pair of circuit traces electrically coupled to each electrode. A non-conductive receptacle is securely adhered on the one end of the elongated strip opposite the contact surface and formed to removably receive an electrocardiography monitor and house a battery. Electrical pads are provided on a bottom surface of the non-conductive receptacle to interface with electrical contacts protruding from the electrocardiography monitor. A pair of the electrical pads is formed to electrically couple with the electrodes. A pair of battery leads is formed on the non-conductive receptacle to electrically interface the battery to another pair of the electrical pads.

A circuit with low voltage energy storage for use in generating a defibrillation waveform is described. A charging circuit includes a pulse capacitor that stores defibrillation energy, a high voltage generator circuit that includes a transformer and a rectification circuit through which the pulse capacitor is charged with the defibrillation energy, and a discharge and polarity control circuit electrically connected to the pulse capacitor and switchable to receive the defibrillation energy, which is output as a defibrillation waveform. A low voltage energy supplementing circuit is electrically connected to the pulse capacitor in line with the high voltage generator circuit and stores supplemental defibrillation energy. A microcontroller is adapted to enable the low voltage energy supplementing circuit to modulate the delivery of the stored supplemental energy to the pulse capacitor to augment the defibrillation energy derived from\the initial defibrillation waveform.

A computer-implemented electrocardiographic data processor with time stamp correlation is provided. A monitoring circuit includes a persistent memory and power supply that powers an encoder that determines a differential voltage between a current discrete digital voltage value and a prior voltage value. The differential voltage is stored into the persistent memory in a digitized data stream representative of analog cardiac action potential signals. Digitally-encoded voltage values and time stamps are retrieved from the persistent memory. A post-processing application executes. A set of output voltages and voltage differences that each correspond to lower and upper bounds of voltage is stored. Each retrieved voltage value is compared to the voltage bounds and the voltage differences within which each retrieved voltage value falls is identified. The output voltages corresponding to the voltage differences is selected. A display depicts the output voltages as reproduced analog cardiac action potential signals and correlates the time stamps.
