"That it will ever come into general use, not withstanding its value, I am extremely doubtful; because its whole hue and character is foreign, and opposed to all our habits and associations.”

"מבלי להמעיט בערכה של צורת בדיקה זו, אני בספק רב אם אי פעם השימוש בה יהפוך

לנחלת הכלל, מפני שכל אופייה ומהותה זרים ומנוגדים להרגלינו ולדרך החשיבה שלנו."

HEMODYNAMICS & PHYSICAL EXAMINATION

- Medical History.- Inspection.- Palpation.- Percussion.- Auscultation.

Antenatal- Family History.- Fetus.- Mother disease.

Perinatal- Delivery.- APGAR score.- First sign & symptom.

InspectionHi, I’m

Alfred E. Neuman, you know, from Mad

magazine?

InspectionWhy, me

worry???

InspectionWhy, me

worry???

InspectionYes, we both

have Williams’ syndrome!

InspectionMe

too!!!

InspectionWith SVAS, SVPS, PPS

and more!!!

The Amplitude of a Murmur

Factors influencing the amplitude grading:- Acoustic energy- Media- Stethoscope- Ears & acoustic nerve- perception

- subjective interpretation

The Pitch of a Murmur

ΔP Pitch

Response to Maneuver

Change in loading condition ( pre/ after load).

Change in loading of right & left cardiac chambers.

Change in timing of auscultatory event.

Change in pressure gradient.
