Cardiovascular Assessment
![Page 3: Cardiovascular Assessment. Heart and Circulation Location and Shape –Precordium –Base –Apex Great Vessels of the Heart –Superior and Inferior Vena Cava.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e4d5503460f94b4292b/html5/thumbnails/3.jpg)
Heart and Circulation
• Location and Shape– Precordium– Base– Apex
• Great Vessels of the Heart– Superior and Inferior Vena Cava– Pulmonary Artery– Pulmonary Veins– Aorta

Heart Structure
• Layers– Pericardium– Myocardium (subendocardium)– Endocardium
• Valves– Semilunar
• Aortic, Pulmonic
– Atriventricular• Bicuspid (Mitral), Tricuspid

Conductance System
• SA node
• AV node
• Bundle of HIS
• Purkinje fibers
• Myocardium
![Page 8: Cardiovascular Assessment. Heart and Circulation Location and Shape –Precordium –Base –Apex Great Vessels of the Heart –Superior and Inferior Vena Cava.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e4d5503460f94b4292b/html5/thumbnails/8.jpg)
Cardiac Cycle
• Diastole– Early filling (passive)– Presystole (Atrial kick) – 25% of stroke
volume
• Systole– AV valves shut (S1)– Pressure builds, shoots through SL valves– SL valves shut (S2)
![Page 9: Cardiovascular Assessment. Heart and Circulation Location and Shape –Precordium –Base –Apex Great Vessels of the Heart –Superior and Inferior Vena Cava.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e4d5503460f94b4292b/html5/thumbnails/9.jpg)
Heart Sounds
• Normal– S1– S2
• Splitting
• Extra– S3– S4
• Murmur
![Page 10: Cardiovascular Assessment. Heart and Circulation Location and Shape –Precordium –Base –Apex Great Vessels of the Heart –Superior and Inferior Vena Cava.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e4d5503460f94b4292b/html5/thumbnails/10.jpg)
Murmur
• Causes– Increased blood velocity– Decreased blood viscosity– Structural defects, especially valve and septal
• Grading: 1 – 6
![Page 11: Cardiovascular Assessment. Heart and Circulation Location and Shape –Precordium –Base –Apex Great Vessels of the Heart –Superior and Inferior Vena Cava.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e4d5503460f94b4292b/html5/thumbnails/11.jpg)
Pumping action
• Preload – volume of blood in heart before systole; also end-diastolic volume (EDV)
• Afterload – diastolic blood pressure; pressure that the heart must overcome to pump blood
• Stroke Volume (SV) – volume of blood pumped in one heartbeat
• Ejection Fraction – SV/EDV
![Page 12: Cardiovascular Assessment. Heart and Circulation Location and Shape –Precordium –Base –Apex Great Vessels of the Heart –Superior and Inferior Vena Cava.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e4d5503460f94b4292b/html5/thumbnails/12.jpg)
Developmental Concerns
• Infants – foramen ovale, ductus arteriosus
• Pregnant – Increase in blood volume
• Aging adult– Systolic pressure increases– Myocardial thickening– Decreased exercise augmentation
