• It is produced during atrial systole and considered as physiologic heart sound.
Characteristics:
• It is short and low pitched sound.
• Duration of the sound is 0.02 -0.04 seconds.
Causes:
• It occurs due to vibrations which set up in atrial musculature during atrial systole.
Fourth heart sound and ECG:
• It coincides with interval between end of 'P' wave and onset of 'Q' wave in ECG.

৩.
The second heart sound is caused by
  1. ক
    closure of the aortic and pulmonary valves.
  2. খ
    vibrations in the ventricular wall during systole.
  3. গ
    ventricular filling
  4. ঘ
    closure of the mitral and tricuspid valves.
৪.
Ejection click occurs following which heart sound?
  1. ক
    1st

Explanation:
Ejection click: an ejection click sound occurs immediately following the first heart sound. The sudden opening of a deformed but mobile aortic or pulmonary valve produces the ejection click.
