A device for measuring and recording body functions can include a first patch and a second patch. The first patch be applied to a user and include an electrocardiogram ("EKG") sensor and a first communication circuit. The EKG sensor can be for recording electrical activity data of a heart of the user. The first communication circuit can be communicatively coupled to the EKG sensors for transmitting the electrical activity data. The second patch can be communicatively coupled to the first patch and include a processing device and a second communication circuit. The processing device can be for performing an analysis of the electrical activity data. The second communication circuit can be communicatively coupled to the first communication circuit for receiving the electrical activity data and communicatively coupled to the processing device for transmitting the analysis to a second device.
