What is percussion of heart?
Tapping with the fingertips (also known as percussion) can be used to estimate the size of the heart, though palpation is more accurate. From the left side of the chest, the doctor can tap the spaces between the ribs with the tips of their middle finger to listen for the dullness that will be present over the heart.
Is the heart enlarged on percussion?
Enlargement of the heart results in more proximate apposition of its chambers to the chest wall, so causing a flatter percussion note above this vicinity and extension of the normal area of marked dullness.
What does percussion mean in medical terms?

Do you Percuss before palpation?
WHEN YOU PERFORM a physical assessment, you’ll use four techniques: inspection, palpation, percussion, and auscultation. Use them in sequence—unless you’re performing an abdominal assessment.

“Your heart is within the limits of normal in size”. As previously posted, heart size has a normal limit range, and if/when it exceeds that, the heart would then be considered as being enlarged, medically termed cardiomegaly. Also, as previously posted, if/when the heart is noted as being borderline, that would specifically be worrisome.
How is percussion used to diagnose heart disease?
Cardiac percussion can be used in diagnosing several conditions: Pericardial effusion can be identified by flat percussion over the lower half or two-thirds of the sternum in the absence of evidence for mitral stenosis.
