Physiological monitoring device

Abstract

The present invention relates to a physiological monitoring device. Some embodiments of the invention allow for long-term monitoring of physiological signals. Further embodiments may also allow for the monitoring of secondary signals such as motion.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 756,326, filed Jan. 24, 2013, entitled PHYSIOLOGICAL MONITORING DEVICE. The contents of the aforementioned application are hereby incorporated by reference in its entirety as if fully set forth herein. The benefit of priority to the foregoing application is claimed under the appropriate legal basis, including, without limitation, under 35 U.S.C. §119(e).BACKGROUND[0002]1. Field of the Invention[0003]The invention relates generally to medical devices. More specifically, the invention relates to a physiological monitoring device and method for use.[0004]2. Description of the Related Art[0005]Abnormal heart rhythms, or arrhythmias, may cause various types of symptoms, such as loss of-consciousness, palpitations, dizziness, or even death. An arrhythmia that causes such symptoms is often an indicator of significant underlying heart disease. It is important to identify w...

Benefits of technology

[0022]In embodiments, the motion signals can be collected in time with the physiological signals. In certain embodiments, a motion artifact is identified when the physiological signals and the motion signals match. Further embodiments may call for an event trigger coupled to the printed circuit board assembly. In some embodiments, the event trigger input is supported by the rigid housing so as to prevent me

Problems solved by technology

Since the symptoms listed above can often be due to other, less serious causes, a key challenge is to determine when any of these symptoms are due to an arrhythmia.

Oftentimes, arrhythmias occur infrequently and/or episodically, making rapid and reliable diagnosis difficult.

The electrodes need daily changing and the wires are cumbersome.

The devices also have limited memory and recording time.

Wearing the device interferes with patient movement and often precludes performing certain activities while being monitored, such as bathing.

All of these limitations severely hinder the diagnostic usefulness of the device, the compliance of patients using the device and the likelihood of capturing all important information.

Lack of compliance and the shortcomings of the devices often lead to the need for additional devices, follow-on monitoring or other tests to make a correct diagnosis.

Current methods to correlate symptoms with the occurrence of arrhythmias, including the use of cardiac rhythm monitoring devices, such as Holter monitors and cardiac eve
