An ECG (Electrocardiogram), or an EKG (Elektrokardiogramm) works by measuring electrical potential between various points of the body using a galvanometer (a very sensitive voltage meter). -DJ Craig

please tell about the BULK and its role in the fabrication of CMOS ?
Most ECG machines calibrate themselves when they are turned on. Older or cheaper models they may need prompting, each is different but the user manual should explain it. Calibration is usually set to 1mV = 10 small squares. This can be manually adjusted if the patient has an unusually large QRS complex. Hope this helps
Digital electronics involves logic 0 and logic 1. It involves the devices and circuits such as gates, flip-flops, latches etc. The basic idea of Digital electronics is mandatory for microprocessor & microcontroller and also for computer architecture. So, any application which involves microprocessor or a computer have digital electronics in it. It can be security applications, error correcting & error detecting , power saving circuits etc.

If the ECG machine malfunctions you will need to redo the test. You can try unplugging the machine and replugging it to see if that resets the system.
It can be tested with something called an ecg simulator.

Willem Einthoven Invented the accurate ECG using Strings Galvonometer, but Alexander Muirhead made the first prototype.
To operate an ECG machine, first ensure the patient is in a comfortable position and has been prepared by cleaning the skin and applying electrodes to specific locations on the chest, limbs, and sometimes the back. Turn on the ECG machine and select the appropriate lead configuration for the test. Instruct the patient to remain still and relaxed while the machine records the electrical activity of the heart, which typically takes just a few minutes. Once completed, review the printed ECG tracing for any abnormalities and ensure proper documentation.
An ECG machine should be calibrated regularly, typically every six months, or whenever it undergoes maintenance or repairs. Additionally, calibration is necessary if there are any signs of malfunction or discrepancies in readings. It’s also advisable to calibrate the machine before use in critical situations to ensure accurate results. Regular calibration helps maintain the accuracy and reliability of the ECG readings.
An electrocardiograph (ECG) machine produces a printed representation on ECG paper by detecting and recording the electrical signals produced by the heart. The machine amplifies these signals and converts them into a visual display on the paper, showing the heart's electrical activity as a series of waves and spikes.
