Eeach electrode connected to the patient is attached to the lead selector of ECG.This will determine which electrodes are necessary for a particular lead and will connect them to the remainder of the circuit. It can be controlled by the operator or by the microcomputer of the electrocardiograph. It selects one or more leads to be recorded.

What are the basic electronics of an ECG machine?
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
How do you calibrate an ecg machine?
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
Which electrode for a ECG is used as the ground?
Right Leg-RL
You had an ECG recently in which the normal rate came to 130.Is this normal with some people or is anything wrong?
what does st elve, probable normal early repol pattern mean and left ventricucular hypertrophy mean
What are 4 signs of death?
There are two ways to determine death in a human being; the cardinal signs method or the clinical method.The three cardinal signs of death are decapitation, decomposition and rigor mortis. Any one present with these signs meet the cardinal sign of death and are pronounced dead immediately.Alternative, to pronounce someone clinically dead, the following factors must be met:- A 3 lead electrocardiogram (ECG) is taken showing asystole.- There is no breathing over one full minute.- The pupils are dilated, unreactive and fully unresponsive.- The patient feels cold and there is an absence of spontaneous circulation.- There is no movement.- Glasgow Coma Scale (GCS) of three.
What is the cause for smeared trace of ECG machine?
LEAD DISPLACEMENT
What to do if the ECG machine malfunction?
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.
How do you if the ECG machine is working correctly?
It can be tested with something called an ecg simulator.
What is ecg machine?
An ECG or EKG machine is a machine that allows the heart to be studied.The machine records the electrical activity with in the heart.ECG means Electyocardiograph
What machine is used to perform the ECG procedure?
ELECTROCARDIOGRAPH
What is the abbreviation for ecg lead v?
vertical
What is the name of the instrument that measures heartbeat?
An ECG (Electrocardiography) machine.
How many lead wires are used to obtain a 12-lead ECG tracing?
FOUR
What type of device helps in measuring brain pulse?
an ecg machine
Who is the first inventor of the ecg machine?
Willem Einthoven Invented the accurate ECG using Strings Galvonometer, but Alexander Muirhead made the first prototype.
What does a heart attack look like on a 12 lead ecg?
ST elevation
Why are the waves in the same direction in an ECG?
The wave direction indicated whether the electrical impulse from the heart is going towards or away from the ECG lead that is being studied.
