Cardiac health monitoring device and a method thereof

A cardiac health monitoring device comprising:

• a battery powered ECG monitor adapted to receive input ECG data signals from two or more electrodes attached to a patient;
• a data acquisition and shield drive selection unit adapted for:
• acquiring the input ECG data signals;
• performing AC coupling of the acquired input ECG data signals;
• and
• providing an RLD drive and integrating the input ECG data signals to have an average which is equal to ADCs mid-range;
• where RLD drive is a continuous average of RA, LA and LL data obtained from the two or more electrodes;
• a signal filtering unit comprising:
• a high pass hardware filter adapted for removing the half-cell DC value to enable the channels to work with AC components;
• a configurable digital decimation filters adapted for:
• band-limiting the input ECG data signals to a preset frequency;
• and
• segregating ECG signals from lead-check, pacemaker identification pulse and impedance measurement signals and related artefacts;
• one or more signal processing units adapted for:
• processing the ECG input signals;
• calibrating an auto-tuning of the processed ECG signals;
• and
• interfacing with a communication unit for transmitting the encrypted ECG signals to one or more external user devices.
