korotkoff sounds phase 1- appearance of clear tapping sounds (SBP) Phase 2- softer and longer phase 3- crisper and louder phase 4- sounds disappear (DBP)
s1 Lub- closure of mitral and tricuspid valves at onset of ventricular systole
s2 closure of aoritic and pulmonic valves at onset of ventricular diastole.
s3 vibrations of the distended ventricle walls due to passive flow of blood from the atria during rapid filling phase. Normal in healthy children, abnormal in adults (associated with heart failure. "ventricular gallop"
s4 pathological. Vibration of ventricular wall with ventricular filling and atrial contraction. Associated with hypertension, stenosis, MI, called atrial gallop
