Question

With the help of electrocardiogram explain different types of waves in normal ECG

Answer 1

Answer:

First of all, we need to know the terminologies :

1. The machine is called a Electrocardiograph

2. The chart is called the Electrocardiogram.

Functions:

It represents the mean instantaneous electrical axis of the heart. Axis refers to the vectors of electrical impulses flowing in the heart.

Components:

Here , we will discuss about the various waves of ECG.

1. P - wave :

It denotes Atrial Depolarization. It is an upward wave . It's duration is 0.1 seconds.

2. QRS complex:

It denotes ventricular Depolarization. It consists of 3 sub-parts ( namely Q wave, R wave and S wave).

It consists of both upward and downward waves. It's duration is 0.8 seconds.

3. T - wave:

It denotes ventricular repolarization. It is also a small upward wave . It's duration is 0.15 seconds.

4. U - wave:

Rarely , this wave is found. It denotes repolarization of the papillary muscles of the ventricles.

This wave is not found in Physiological conditions.
