The human heart is a vital organ that pumps blood throughout the body. The apex beat is a term used to describe the rhythmic pulsation that can be felt at the bottom of the heart. It is an essential aspect of cardiovascular examination and can reveal important information about the patient’s health.
Definitions
The apex beat is defined as the point of maximal impulse (PMI) of the heart, which is the point where the heart’s pulsation is most prominent. It is located at the fifth intercostal space, mid-clavicular line, and is usually felt as a gentle tapping or thumping sensation.
Origin
The origin of the term apex beat can be traced back to the Latin word “apex,” meaning the tip or point of something. In the context of the heart, the apex refers to the lowermost part of the heart, which is pointed and extends towards the left side of the body.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, the apex beat is defined as “the beat of the heart as felt through the chest wall at the point of maximum impulse.” The Oxford English Dictionary defines it as “the point on the chest wall where the heartbeat is most easily felt.”

The apex beat is associated with various cardiovascular conditions. For example, a displaced or diffuse apex beat can indicate an enlarged heart or fluid accumulation around the heart. A weak or absent apex beat can indicate a weakened heart muscle or a condition called pericarditis, which is inflammation of the membrane surrounding the heart.
