PMI: Point of maximal inspection: the site where maximum beat can be heard it is present in 5th intercostal space at the midclavicular line(9cm from mid sternum).
Cardio-Thoracic ratio: it shows the position of the heart and its size in the chest cavity with the help of a chest X-ray of a person.

*Abnormal heart sounds or heart murmurs
it can be due to the

Types of abnormal heart sounds:

It is of three types;

*Contraction of ventricles

Ventricular contractions
Ventricular contractions

Hypertrophy: Increase in size of the heart.
Types: There are two types depending upon the diameter of the ventricular cavity.

Premature heartbeats
It can be in atria or ventricle.
1.Atrial premature contraction
ii.Ventricular premature contraction
