Significance of Apex beat

Mechanism of production
Apexbeat is produced due to the counter-clockwise rotation of the left ventricle in early systole followed by recoil back in late systole
Normal apical impulse is produced bv left ventricle and the left vuntricular portion of the interventricular septum.
What are the factors affecting the apical impulse formation:
  • Left ventricular size
  • Left ventricular filling, force and duration of contraction
