Patent number: 10264992Abstract: Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended wear electrode patch with sewn electrodes and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline, with its unique narrow “hourglass”-like shape, significantly improves the ability of the wearable monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and the QRS interval signals indicating ventricular activity in the ECG waveforms. In particular, the ECG electrodes on the electrode patch are tailored to be positioned axially along the midline of the sternum for capturing action potential propagation in an orientation that corresponds to the aVF lead used in a conventional 12-lead ECG that is used to sense positive or upright P-waves.Type: GrantFiled: July 27, 2017Date of Patent: April 23, 2019Assignee: Bardy Diagnostics, Inc.Inventors: Jason Felix, Jon Mikalson Bishay, Gust H.
