INTRODUCTION
The experiment on the electrocardiography registers the heart movements using electrical signals
over a given period. It is used as the gold customary for identification of the cardiac arrhythmias
and helps detect electrolyte disturbances that may result from hyperkalemia and the
hypokalemia. It consents to the detection of conduction aberrations. The selection tool is used for
the ischemic heart disease over the stress tests and is supportive with non-cardiac diseases such
as the pulmonary embolism or the hypothermia.

In this experiment, the amplitude values are recorded and they are estimated to be smaller as
compared to the electrodes that are placed in close contact with the heart muscle membrane. The
anticipated range is estimated to be high as 110mV.
AIMS & OBJECTIVES
(i) To comprehend the ECG records and the human heart electrical activity.
(ii) To use software and the Bitalino kit to determine, analyze, and discuss the ECG of
the human body using other simulators.
