Korotkoff’s SoundsKorotkoff’s Sounds
Sounds heard during auscultation of blood pressure.
Produced by vibratory motion of the arterial wall as the artery suddenly distends when compressed by a pneumatic BP cuff.
Origin of sound may be within the blood passing through the vessel wall or within the wall itself.
5 distinct Korotkoff sounds heard during auscultation of BP– 1st - beat or tapping sound– 2nd - murmur or swish sound– 3rd - crisp tapping sound– 4th - soft, muffled tone– 5th - the last sound heard
Systolic - The first beat or tapping heard Diastolic - The fourth sound heard
Blood Pressure MeasurementBlood Pressure Measurement
Materials needed:
– Stethoscope
– Sphygmomanometer
– Alcohol sponge Choose cuff of appropriate size
– Too narrow may cause falsely high pressure
– Excessive wide a falsely low pressure
Patients arm should be extended at heart level.– Artery above or below heart level, blood
pressure may be elevated or decreased consecutively.
Wrap deflated cuff snugly around upper arm– Above antecubital area inner aspect of elbow.– Center of bladder should rest directly over
medial aspect of arm. (Most cuffs have an arrow for you to position over brachial artery at where you feel strongest pulse)
Place Bell of stethoscope on brachial artery at point of strongest pulse
Locate brachial artery by palpation. Center the bell over the artery and hold it
in place with one hand. The bell of the stethoscope transmits low pitched arterial blood sounds more effectively than the diaphragm.
Pump air into cuff while auscultating the sound over brachial artery - until gauge registers 160mm HG or at least 30 mm Hg above last audible sound.
Open valve and slowly deflate the cuff - 5 mm Hg / second. While releasing air - watch the column and auscultate the sound over the artery.
When you hear the first beat or clear tapping note pressure on column. This is the SYSTOLIC pressure.
Continue to release air gradually. Note the fourth Korotkoff sound (a soft,
muffled tone) This is the DIASTOLIC pressure.
Deflate the cuff quickly.
Problem and Possible Cause for:
– False-high reading Cuff too small - (bladder must be approximately
20% wider than the circumference o f arm). Cuff wrapped too loosely, reducing effectiveness
(tighten cuff) Slow cuff deflation, causing venous congestion in
arm ( Never deflate the cuff more slowly than 2 mm Hg/ heartbeat)
Tilted mercury column (Read pressure column vertically)
Poorly timed measurement -after eating, ambulated, appeared anxious, or flexed arm muscles.
– False-low reading Incorrect position of arm (make sure the
arm is level with patient’s heart) Mercury column below eye level (Read
the mercury column at eye level) Failure to notice auscultatory gap (sound
fades out for 10 - 15 mm Hg, then returns (estimate systolic pressure by palpation before actually measuring it)
Inaudible low-volume sound (Chart as the palpated systolic pressure)
Heart RateHeart Rate Gently press your index, middle, and ring
finger on the radial artery, inside the patient’s wrist.
Count the beats for 60 seconds, or for 30 seconds and multiply by 2. (60 second count more efficient.)
Assess rhythm and volume by noting the pattern and strength. If you detect an irregular beat, repeat the count. IRREGULARITIES ARE IMPORTANT SIGNS

– Palpable vibration associated with a murmur or bruit
– Felt where the murmur is heard the loudest or a location of a bruit.
Murmur - a periodic sound of short duration intracardiac in origin.
Bruit - a sound or murmur heard, extracardiac.
AuscultationAuscultation Stethoscope
– snug fitting earplugs
– Tubing two tubings preferable for high
frequency sounds Not longer than 12 to 15 inches
– Chest Piece Diaphragm - held firmly against skin
–Used for high pitched sounds
• S1, S2 and splits, pericaridal friction rubs, most murmurs
Bell- held tightly enough against skin to create seal
Used for low pitched sounds: S3, S4
Auscultation Areas
– Aortic - 2nd RICS at Right sternal border
– Pulmonic - 2nd LICS at Left sternal border
– Erb’s Point - 3rd LICS at Left sternal border
– Tricuspid - 5th LICS at Left sternal border
– Mitral - 5th LICS at mid-clavicular line
Auscultation should be performed in each of the five cardiac areas– use of the diaphragm first, then the bell of the
stethoscope. Using firm pressure with the diaphragm and light pressure with the bell
– Assess the overall rate and rhythm of the heart -noting the area being accessed.
– Breathing normally, then holding breath listen for S1 while palpating the carotid pulse. S1 coincides with the rise of the carotid pulse. (Systole)
– Note the intensity, any variations, the effect of respiration and any splitting of S1
Basic Heart SoundsBasic Heart Sounds
There are four basic heart sounds: S1, S2, S3 and S4. S1 and S2 are the most distinct heart sounds.
S3 and S4 may or may not be present; their absence is not an unusual finding, but their presence does not necessarily indicate a pathologic condition.
Rules to considerRules to consider Left sided heart events precede right side
(mitral component precedes tricuspid of S1, Aortic event precedes pulmonic of S2)
Left sided heart events are normally loudest during expiration, and right sided events are normally loudest during inspiration.
S1 is the result of the closure of the AV valves– indicate the beginning of systole and is best
heard toward the apex where it is usually louder than S2
S2 is the result of closure of the semi-lunar valves and indicates the end of systole– indicates the end of systole and is best heard
in the aortic and pulmonic areas.
Heart sounds according to Heart sounds according to Cardiac AreaCardiac Area Aortic area
– Loudness - S1< S2
– Duration - S1 > S2
Pulmonic area – Loudness - S1 < S2
– Duration - S1 > S2
Erb’s Point– Loudness - S1 < S2
– Duration - S1 > S2
Mitral area– Loudness - S1 > S2
– Duration - S1 > S2
Tricuspid Area– Loudness - S1 > S2
– Duration - S1 > S2
Splitting of SSplitting of S11 and S and S22 S1
– usually is not heard because the sound o the tricuspid valve closing is too faint to hear.
– Heard best when audible in the tricuspid area S2
– Expected due to the higher pressures and depolarization occurs earlier on the left side of the heart.
– Ejection times on the right are longer and pulmonic valve closes a bit later than the aortic valve.
SS11 and S and S22 Split Split
S1 is the result of closure of the AV valves - indicating the beginning of systole. Mitral and Tricuspid valves.
Heard best at tricuspid area on inspiration.
Although there is some asynchrony between closure of the mitral and tricuspid valves - usually heard as one sound.
Narrowly split may be normal
A split S1 is more abnormal than normal and is associated with any one of the following:– RBBB– Left ventricular (epicardial) pacemaker– Left ventricular ectopy
Split S2
– Both Aortic and Pulmonic components can be heard
– Inspiratory only is normal Called physiologic split of S2
Split ONLY during inspiration Caused by intra-thoracic changes in
pressure; increased venous return to right and decreased venous return to left
Expiratory Split of SExpiratory Split of S22
Increased splitting during inspiration (split on expiration but split more on inspiration)
– RBBB (Right Bundle Branch Block)
– Left ventricular ectopy
– Severe mitral regurgitation
– Ventricular septal defect
SS33
Ventricular gallop Occurs early in diastole Caused by rapid rush of blood into a
dilated ventricle. Heard best with bell Associated primarily with Heart Failure
Associated with:– Fluid overload– Cardiomyopathy– Ventricular septal defect– Mitral or tricuspid regurgitation
– __S1____S2__S3
SS44
Atrial Gallop Dull, low pitched occurring late in diastole
before S1.. Caused by atrial contraction and
propulsion of blood into a non-compliant ventricle
Heard best with bell
Associated with:– Myocardial ischemia or infarction– Hypertension– Ventricular ectopy– AV blocks– Severe aortic or pulmonic stenosis.
__S4__S1___S2__
Extra Heart Sounds:Extra Heart Sounds: Summation gallop
– All four heart sounds plus tachycardia
– Merging of S3 and S4 causing a louder mid-diastolic sound
Pericardial friction rub– scratchy sound - usually
triphasic; systolic, early and late diastolic
– Caused by pericardial inflammation
after MI or CABG
Snaps– Opening snap
Short, high-pitched; early diastole
Caused by:– Opening of
stenotic AV valve
– Increased flow– closing snap
Really a loud S1
Caused by closure of AV valve
MurmursMurmurs Caused by turbulence
– Increased flow through a normal valve– Forward flow through a stenotic valve– Backward flow through a regurgitant valve
(insufficient or incompetent)– Flow through a AV fistula or septal defect– Flow into a dilated chamber or a portion of a
vessel
Description– Timing
Systolic– Holosystolic: AV regurgitation or VSD– Midsystolic (Ejection) - Semilunar stenosis– Late - papillary muscle dysfunction;
Hypertrophic cardiomyopathy (IHSS) Idiopathic hypertrophic subaortic stenosis.
