A medical device configured to be adhesively coupled to an external surface of a subject, and to facilitate physiological monitoring of the subject, includes: a first portion having a housing that at least partially encloses an interior chamber and has a grip portion that has a peanut-like shape; and a second portion including a flexible patch configured to facilitate operably coupling the first portion to the subject. The flexible patch includes third and fourth sensor connections configured to operably interface with the first and second sensor connections, respectively; first and second sensing elements; and a flexible circuit assembly configured to electrically couple the third sensor connection to the first sensing element and the fourth sensor connection to the second sensing element. An adhesive assembly is configured to couple the first portion to the second portion, and includes conductive adhesive portions.

A system for facilitating a cardiac rhythm disorder diagnosis with the aid of a digital computer is provided. A download station retrieves cutaneous action potentials of a patient by an ECG monitoring and recording device as ECG data. An R-R interval plot of the ECG data includes heart rates associated with R-R intervals plotted along a y-axis of the plot with respect to time, with time represented by an x-axis. The R-R intervals are calculated as a difference between recording times of successive pairs of R-wave peaks and each heart rate is associated with each time difference. Runs of the R-R intervals in the plot are identified and each run represents a cardiac event. Cardiac rhythm measurements are automatically calculated and occurrences of different types of the cardiac events are tracked. One or more of the cardiac events and the cardiac rhythm measurements are reported.

An ECG electrode includes a substrate and one or more holes. The substrate includes on one side an electrolyte gel for contacting a patients skin and an adhesive. The one or more holes perforate the substrate and the adhesive to increase the adhesion between the patients skin and the substrate. The one or more holes can have a circular shape, rectangular shape, crescent shape, polygonal shape, elliptical shape, diamond shape, star shape, or triangular shape. A method for manufacturing an ECG electrode includes assembling a substrate that includes on one side an electrolyte gel for contacting a patients skin and an adhesive and creating one or more holes in the substrate and the adhesive that increase the adhesion between the skin and the substrate. The one or more holes are created using a laser or a drill.

A hydrogel pad is configured for use with an electrode or a wearable device to measure vital signs of a patient. The hydrogel pad includes a flexible support having one or more openings in which hydrogel is disposed. A membrane covers one side of the hydrogel to protect it from gaining or losing too much moisture. A removable backing covers the other side of the hydrogel until it is applied to a patient, at which point the other side contacts the patient's skin. The protective membrane can be pierced by an angular conductive contact of a device to contact the hydrogel creating an electric conduit between the patient and the device. When the device is removed, the membrane at least partially closes to cover and protect the hydrogel.
