CARDIAC PERFORMANCE MONITORING SYSTEM FOR USE WITH MOBILE COMMUNICATIONS DEVICES

摘要

Described herein are apparatuses (e.g., devices, systems, software), and methods for monitoring the cardiac health of a patient. The apparatuses and methods may include a smartphone or hand held computing device having an accelerometer. The apparatus may also include a device with a plurality of electrodes integral with or attached to the smartphone. The devices can be placed on a patient's chest to measure electrical signals and vibrations on the chest caused by the heartbeat. The measurements can generate a seismocardiogram (SCG) and in some variations an electrocardiogram (ECG). The apparatuses and methods can analyze the data in the SCG to produce a measure of the cardiac function. Changes in such measures can provide an early warning for potential cardiac problems and signal the need for the patient to seek treatment prior to a fatal cardiac event.

主权项

1. A non-transitory computer-readable storage medium storing a set of instructions capable of being executed by a smartphone having an accelerometer, that, when executed by the smartphone, causes the smartphone to record both a seismocardiogram (SCG) from the smartphone's accelerometer by detecting vibrations on a patient's chest corresponding to heart motion for a first time period and to detect an electrocardiogram (ECG) from the patient's chest, further wherein the set of instructions, when executed by the smartphone, cause the smartphone to do at least one of: analyze the SCG to determine an index of cardiac function, display the SCG, transmit the SCG, store the SCG, display the ECG, transmit the ECG, or store the ECG.
