Health & Physical Assessment in Nursing, Second Edition Donita D’Amico Colleen Barbarito THE HEART AS A PUMP: THE CARDIAC CYCLE OF SYSTOLE AND DIASTOLE Systole: the ventricles contract The phase of ventricular contraction in which the ventricles have been filled, then contract to expel blood into the aorta and pulmonary arteries. -The right ventricle pumps blood into the pulmonary arteries (pulmonic valve is open) -The left ventricle pumps blood into the aorta (aortic valve is open) Diastole: the ventricles relax The phase of ventricular relaxation in which the ventricles relax and are filled as the atria contract -Blood flows from the right atrium → right ventricle (tricuspid valve is open) -Blood flows from the left atrium → left ventricle (mitral valve is open)

Copyright ©2012 by Pearson Education, Inc. All rights reserved. Health & Physical Assessment in Nursing, Second Edition Donita D’Amico Colleen Barbarito THIRD & FOURTH HEART SOUNDS Description: Both sounds are low frequency and thus best heard with the bell of the stethoscope. Location: Usually best heard over apex with patient in the left lateral position

Copyright ©2012 by Pearson Education, Inc. All rights reserved. Health & Physical Assessment in Nursing, Second Edition Donita D’Amico Colleen Barbarito THIRD HEART SOUND S3 Results from increased atrial pressure leading to increased flow rates, as seen in congestive heart failure, which is the most common cause of a S3. May be normal physiological finding in patients less than age 40.

Copyright ©2012 by Pearson Education, Inc. All rights reserved. Health & Physical Assessment in Nursing, Second Edition Donita D’Amico Colleen Barbarito FOURTH HEART SOUND S4 Seen in patients with stiffened left ventricles, resulting from conditions such as hypertension, aortic stenosis, ischemic or hypertrophic cardiomyopathy.

Copyright ©2012 by Pearson Education, Inc. All rights reserved. Health & Physical Assessment in Nursing, Second Edition Donita D’Amico Colleen Barbarito MURMURS Murmurs are extra heart sounds that are produced as a result of turbulent blood flow that is sufficient to produce audible noise. Murmurs may also be the result of various problems, such as narrowing or leaking of valves.

Health & Physical Assessment in Nursing, Second Edition Donita D’Amico Colleen Barbarito INSPECTION OF THE FACE AND LIPS Skin color changes may indicate cardiovascular disease. For example, pallor and cyanosis of lips or extremities are associated with decreased perfusion.

Health & Physical Assessment in Nursing, Second Edition Donita D’Amico Colleen Barbarito Jugular Venous Pressure (JVP) and Pulsations Recall that jugular veins reflect right atrial pressure Steps for examination –Raise the head of the bed or examining table to 30° –Turn the patient’s head gently to the left –Identify the topmost point of the flickering venous pulsations –Place a centimeter ruler upright on the sternal angle –Place a card or tongue blade horizontally from the top of the JVP to the ruler, making a right angle –Measure the distance above the sternal angle in centimeters: a 3- to 4-centimeter elevation is normal
