Electrodes on the skin are used to record the electrical activity produced by the heart during myocardial contraction and relaxation. Heart rate, heart rate variability, waveform shape analysis, arrhythmia, and other comparable functions are all investigated using ECG signals . However, clean recording signals can be difficult, especially when doing a 12-lead ECG. There are several factors to consider. The data recording equipment must be set up correctly, the subject must be comfortable, and the surface electrodes must be placed exactly on the subject's torso and limbs to obtain reliable findings. As a result, a cheap diagnostic centre in Mumbai provides world-class services and the most advanced equipment. Here are some lists of a simple guide for ECG placement for researchers. Prepare the Skin Before placing your electrodes, make sure the subject's skin is clean by washing the chest area with skin cleansing swabs. This gets rid of any oil on your skin that could be ca
