The apex beat may also be displaced by other conditions: Pleural or pulmonary diseases; Deformities of the chest wall or the thoracic vertebrae; Sometimes, the apex beat may not be palpable, either due to a thick chest wall, or conditions where the stroke volume is reduced; such as during ventricular tachycardia or shock.
The apex beat is assessed for size, amplitude, location, impulse and duration. There are specific terms to describe the sensation such as tapping, heaving and thrusting. Often the apex beat is felt diffusely over a large area, in this case the most inferior and lateral position it can be felt in should be described as well as the location of ...
Mid-pupillary line: A line running vertically down the face through the midpoint of the pupil when looking directly forward. Mid-inguinal point: A point midway between the anterior superior iliac spine and the pubic symphysis.

A forceful apex beat indicates left ventricular pressure overload, while a right ventricular heave suggests right ventricular pressure overload. Other signs provide evidence for specific causes of pressure overload. Hypertension is diagnosed by sphygmomanometry.
The term "rostral" is rarely used in human anatomy, apart from embryology, and refers more to the front of the face than the superior aspect of the organism. Similarly, the term "caudal" is used more in embryology and only occasionally used in human anatomy. [2]

An S3 heart sound is best heard with the bell-side of the stethoscope (used for lower frequency sounds). A left-sided S3 is best heard in the left lateral decubitus position and at the apex of the heart, which is normally located in the 5th left intercostal space at the midclavicular line.
