Basics Cardiology - Clin Med
Solved Questions with Clear
Explanations Included
What valves are closing for the S1 sound? - answer Mitral and
tricuspid
Closure of what valves causes the S2 sound? - answer Atrial and
pulmonic
What causes the S3 sound? - answer when the blood refills the
ventricles
What can an S3 sound be an early clinical sign of what? - answer
Congestive heart failure
What can cause the S4 sound? - answer the atria contracting to
ensure the ejection of any remaining blood
what is the beginning of the cardiac cycle? - answer ventricular
contraction
What is preload? - answer the end diastolic volume and the
resultant fiber length of the ventricles prior to the onset of the
contraction
what is after load? - answer the resistance to left ventricular
ejection and outflow, or the stress on the ventricular wall at the end
of systole
