Motion resistant device to monitor heart rate in ambulatory patients

A device for continuous, mobile, ambulatory diagnostic monitoring for heart rate disease and abnormal conditions, the device comprising:

• an article attached to the user;
• an optical sensor connected to the article, the optical sensor generating a real-time digital signal corresponding to a flow of blood through an artery of the user;
• an accelerometer connected to the article, the accelerometer generating a real-time accelerometer data comprising a X-axis signal, a Y-axis signal and a Z-axis signal based on a movement of the user;
• a processor connected to the article, the processor configured to receive the real-time digital signal from the optical sensor and configured to receive the real-time accelerometer data from the accelerometer, the processor configured to generate a motion Comb filter value from the real-time accelerometer data utilizing an array of Comb filters, the processor configured to generate a real-time heart rate for the user based on the real-time digital signal filtered by the motion Comb filter value and a heart rate Comb filter value;
• and
• a display for displaying the real-time heart rate value for the user received from the processor;
• wherein the processor determines a real-time heart rate of the user by generating a first heart rate value from a first filtered pulse data value which is generated from subtracting an average value of a second set of sample data values from an average value of a first set of sample data values, and wherein the processor uses a cascade adaptive resonant filter to generate subsequent heart rate values.
