Exam 2: Cardiovascular Assessment Part 2 Flashcards
What does an aortic or pulmonic ejection click sound like and what does it indicate?
- High pitched sound at beginning of systole
- indicated valve disease, dilated aorta or pulmonary artery, or pulmonary hypertension
** Best heard with diaphragm of stethoscope
What is a mitral valve prolapse?
Ballooning of mitral leaflets into the left atrium during systole.
-Mid to late systolic clicks are often present.
What causes venous hum?
- Turbulent blood flow through jugular veins
- both systolic and diastolic sounds
What causes pericardial friction rub and what are the 3 components of it?
- Caused by inflammation of pericardial sac
- 3 components are scratchy, squeaky, and intermittent
What does increased jugular pressure indicate?
- Increased pressure in the right atrium related to intravascular fluid volume
- Mainly reflect right heart function
What is best used to assess jugular venous pressure?
Right internal jugular vein or external jugular vein
How do you perform the specialized exam of measurement of JVP?
Stand on the patients right with the exam table at 30 degrees.
Patients head is turned slightly to the right. Find the highest point of oscillation in the right internal jugular vein.
Measure the vertical distance above the sternal angle.
Add 5 cm and the sum is JVP.
What can cause increased JVP?
Hypervolemia from heart failure, pulmonary HTN, increased venous vascular tone, and pericardial tamponade
What is considered an elevated JVP?
8cm above the RA
What causes decreased JVP?
Hypovolemia due to blood loss or decreased venous vascular tone
How do you perform the specialized exam Hepatojugular reflux?
Patient is supine with the exam table at 30 degrees. Apply firm, sustained pressure to the abdomen in the RUQ over the liver region. Observe the neck for an increase in JVP, followed by a decrease when the hand is released.
JVP will transiently increase in all patients, but is exaggerated in right heart failure.
What is a positive hepatojugular reflex?
Greater than 3cm increase, or is remained elevated.
What is a thrill and what causes it?
Buzzing or vibratory sensation, caused by vigorous blood flow through any narrowed opening.
What is a lift (or heave) and what causes it?
Vigorous cardiac impulse that can be seen/felt through the chest wall, may be caused by ventricular hypertrophy or hyperdynamic ventricular activity.
Where should you palpate when checking for lifts and thrills?
The left sternal border
