The various embodiments of the present invention disclose a stand-alone, scalable cardiac health monitoring device for 1-6-12 lead ECG data acquisition and a method of working thereof. The method of monitoring cardiac health condition of a patient comprises of receiving, by a cardiac monitoring device, an electrocardiograph (ECG) input data signals from at least two electrodes attached to the patient, performing, a quality check on acquiring the ECG input data signals, processing the acquired ECG input data signals, encrypting the processed ECG input data signals and transmitting the encrypted ECG signals to one or more external user devices over a wireless communication interface. The acquiring the ECG input data signals comprises of integrating a closed loop Right Leg Drive (RLD) as a shield drive and a cable/electrode shield to reduce noise coupling to the ECG input data signals.

An electrode system includes an electrode, a connector, and a cable with an in-line radio-frequency filter module comprising resistors and inductors without any deliberately added capacitance. The resistors are arranged in an alternating series of resistors and inductors, preferably with resistors at both outer ends, and connected electrically in series. The in-line module is located at a specific location along the wire, chosen through computer modeling and real-world testing for minimum transfer of received RF energy to a patient's skin, such as between 100 cm and 150 cm from the electrode end of a 240 centimeter cable. The total resistance of the resistors plus cable, connectors and solder is 1000 ohms or less; while the total inductance is roughly 1560 nanohenries. The inductors do not include ferrite or other magnetic material and are, together with the resistors, stock components thereby simplifying manufacture and reducing cost.

A probe tip of an oximeter device includes first and second printed circuit boards (PCBs) that are coupled to the ends of optical fibers that transmit light between the PCBs and into patient tissue that is to be measured by the oximeter device. The PCBs are oriented at an angle between zero and ninety degrees so that the fibers have a curved shape between the locations at which the fibers are coupled to the first and second PCBs. The angular orientation of the PCBs and curved shape of the fibers allows the fibers to have a longer length than if the fibers were straight and allows for light transmitted through the fibers to have a uniform distribution across a cross-section of the fibers as the light is emitted from the fibers into patient tissue. The uniform distribution of light transmitted into patient tissue allows for reliable oximetry measurements.
