More Information
The apex beat, also known as the point of maximal impulse (PMI), is the outermost and lowermost point of visible or palpable pulsation on the chest wall.
Tips
A common mistake is confusing the anatomical terms describing the location, such as mixing up 'left midclavicular line' with the 'left midsternal line'.
