Detection of relative dullness
1.Right border:
Is formed by RA
Localized along right sternal line
Detection of relative dullness
2. Left border:
Is formed by LV
Is detected after palpation of apex beat
Is located 1-2 cm medialy from left midclavicular line
Fits in with apex beat
Detection of relative dullness
3. Upper border:
Is formed by LA appendage and pulmonary trunk
Is percussed 1 cm laterally from sternal line
Is located along the 3rd rib
Transverse size of the heart
Distance from right and left border to median anterior line
Normally:
3-4 см + 8-9 см = 11-13 см
Borders of vessel bundle
Vessel bundle: aorta
superior cava vein pulmonary artery
Quiet percussion along II space
Normally the borders consist with Sternal margins
width 5-6см
Dilation:
Aortic aneurism, pulmonary hypertension
Absolute dullness
Central part of the heart not covered with the lungs
Right border: along left sternal margin.
Left: 1 - 2 см medially from the left border of relative dullness
Upper: IV rib
Configuration of the heart

Normal configuration of the heart.
Waist of the heart is detected between vessel bundle and LV
1 — контуры относительной тупости;
2 — абсолютная тупость;
3 — талия сердца.
Mitral configuration
Flattening of the heart due to LA dilation
Aortic configuration
Pronounced cardiac waist due to LV dilation
