CARDIOVASCULAR EXAMINATION AssocProf Elif Eroğlu Büyüköner October 2013
EXAMINATION of the CARDIOVASCULAR SYSTEM • General inspection • Specific inspection • Pulse • Carotid • Neck veins • Praecordium • Auscultation • Lung bases,liver, ankles • Veins and arteries in the legs
GENERAL INSPECTION • General build and appearence • Colour • Respiration (abnormal breathing pattern, shortness of breath) • Signs of distress and response • Conscious level
SPECIFIC INSPECTION • Cyanosis • Central: mucous membranes-tongue • Peripheral: extremities • Clubbing • Anemia • Edema • Peripheral perfusion • Body habitus • Specific signs of cardiac pathologies: IE stigmata, arcus senilis, xanthome and xanthelasma
Signs of atherosclerosis Xanthelesma Arcusjuvenilis Signof prematureatherosclerosis xanthoma
The PULSE • Rate • Normal sinus 60-100bpm • Sinus bradycardia <60 bpm • Sinus tachycardia >100 bpm • Regularity • Sinus arrhytmia: varies with respiration • Intermittant irregularity: ectopic beats • Continously irregular: atrial fibrillation
Carotid examination • Carotid upstroke • Brisk/normal/delayed • Volume:increased/normal/decreased • Anacrotic/bisferiens • Carotid auscultation • Bruit • Transmitted murmur • A2 audible in the neck
Carotid pulse contour • A. Hyperkinetic:AR • B.Bisferiens: AS/AR • C.Bifid: IHSS • D.Hypokinetic/alternans: LVD • E.Parvus et tardus: AS
a wave - atrial systole x descent – onset of atrial relaxation c wave - small positive notch in the 'x' descent due to bulging of the AV ring into the atria in ventricular contraction. x' (prime) descent !!! occurs during systole due to RV contraction pulling down the TV valve ring “descent of the base” a measure of RV contractility v wave - after the x' descent - slow positive wave due to right atrial filling from venous return y descent - rapid emptying of the RA into RV due to TV opening Normal JVP waves and descents
Abnormal “a” wave • AV valve obstruction: TS, RA myxoma • Decreased RV compliance:RVH, PS, PHT • AV dysassociation:AV blocks, “Cannon” a waves • Severe HCM: Bernheim effect • No visible “a” wave in AF
X’ descent • Beginning of the RA diastole, before venous filling to the RA, during RV systole. RVFW moves to the septum, TV moves to the apex and RA base is pulled down (RA pressure falls) • More prominent during inspiration • Increases with RV contractility:tamponade • RV volume inc: ASD, VSD • RV pressure inc: PD, PHT • Decreases in RV contractility: reduced x’
v wave • RA filling, together with S2 • Severe TR: CV fusion, no X’ descent y descent • RV filling (early diastole) • Inc: TR, CP, RCM • Dec: Tamponade, TS
Apical Impulse: • Visualization to assess ventricular size/thickness • Normally distinct and located at 4ICS at/inside the midclavicular line
Apical Impulse (abnormal): • Hyperdynamic impulse in normal location: think increased cardiac output or LVH • Hyperdynamic and downward/leftwardly displaced: think LVE • Indistinct impulse associated with RVH • Precordial heave is seen with RVE
Thrills: • Palpation of a loud murmur • Found in the precordial, suprasternal, or carotid artery area • If low intensity murmur, probably just a pulsation and NOT a thrill
S1 (cont.): • If split heard better at the apex, may actually be S4 or ejection click • Tends to be more low-pitched and long as compared to S2 • Differentiate S1 from S2 by palpating carotid pulse: • S1 comes before and S2 comes after carotid upstroke
Decreased S1: • Slowed ventricular ejection rate/volume • Mitral insufficiency • Increased chest wall thickness • Pericardial effusion • Hypothyroidism • Cardiomyopathy • LBBB • Shock • Aortic insufficiency • First degree AV block
Other Abnormal S1 (cont.): • Increased S1: • Increased cardiac output • Increased A-V valve flow velocity (mitralstenosis)
S2: • From closure vibrations of aortic and pulmonary valves • Divided into A2 and P2 (aortic and pulmonary closure sounds) • Best heard at LMSB/2LICS • Higher pitched than S1/better heard with diaphragm
S2 splitting (normal): • Normally split due to different impedance of systemic and pulmonary vascular beds • Audible split with > 20 msec difference • Split in 2/3 of newborns by 16 hrs. of age, 80% by 48 hours • Harder to discern in heart rates > 100 bpm
