Cardiovascular System Exam Purpose?

To evaluate potential causes of poor performance or collapse.

Peripheral Oedema Cause?

Right-sided cardiac failure often leads to fluid accumulation in the extremities.

Tricuspid Valve Auscultation?

Beneath the triceps muscle, at the 5th left intercostal space.

Abnormal Contraction Manifestation?

Abnormal heart muscle contractions can cause unusual heart sounds.
