Shadow Health Cardiovascular Concept

Which chambers receive blood? -right and left atria Which chambers pump the blood out? -right and left ventricles The right atrium receives the systemic venous return from what? -interior vena cava and superior vena cava The blood through the right atrium is oxygenated for deoxygenated? -deoxygenated due to the travels through the body -The right atrium collects the deoxygenated blood and directs it into what through the what valve? The right ventricle and tricuspid valve The right ventricle is the pumping chamber on what side of the heart? -right the right ventricle pump the deoxygenated blood through what valve into this artery? -pulmonic valve and pulmonary artery The two main branches of the pulmonary artery deliver the pulmonary cardiac output into what for oxygenation? -lungs What collects the pulmonary venous return from four main pulmonary veins? -left atrium These veins contain oxygenated blood -pulmonary veins These veins contain deoxygenated blood -systemic veins The left atrium directs oxygenated blood through what into the left ventricle. -mitral What is the pumping chamber on the left side of the heart? -left ventricle Left ventricle generates roughly 5x the pressure of the RV, it pumps the oxygenated blood through what and into what? -through aortic valve into the aorta, and throughout the body. This sound occurs when the mitral and tricuspid valves close. -S1 This heart sound occurs with the closing of the aortic and pulmonic valves. -S2 When auscultating for the aortic area, where do you place your stethoscope? -On the 2nd right intercostal space at the upper right sternal border Where do you place your stethoscope when auscultating for the pulmonic area? -on the 2nd left intercostal space at the upper left sternal border Where do you place your stethoscope when auscultating for Erb's point? -on the 3rd left intercostal space at the medial left sternal border. (it can only be heard in the left lateral recumbent position) Where do you place your stethoscope when auscultating for the tricuspid area? -on the 4th left intercostal space at the left sternal border Where do you place your stethoscope when auscultating for the mitral area (sometimes called the? apical area) -at the apex of the heart on the 5th left intercostal space at the midclavicular line Ventricular gallop is what number of heart sounds? -S3 This heart sound has low-frequency vibration occurring after S1 and S2 and seems to result from the change in blood flow in the diastole when rapid filling ends and slow filling starts -ventricular gallop (S3) when listening for S3, the heart sounds resemble the pronunciation of what word? -Ken-TUCK-y, with the y representing S3. (best heard with the bell of the stethoscope. sometimes it is normally heard in those under the age of 40 and trained athletes) atrial gallop is what number heart sound? -S4 This heart sounds is a low-frequency sound that occurs in late diastolic filling due to atrial contraction. This causes vibrations in the ventricular walls and happens just before S1, making it difficult to hear -atrial gallop, S4 This heart sound resembles the pronunciation of what word? -TEN-nes-see where TEN is S4 (when it is clearly heard it can indicate an increased resistance to ventricular filling. Sometimes S4 can occur normally in people older than 40, especially after exercise.) what is tachycardia? -rapid resting heart rate of over 100 bpm what is bradycardia? -slow resting heart rate of less than 60 bpm This sound is generated from inflammation of the pericardial sac as it rubs against the linings surrounding the heart, and is not really a heart sound. -pericardial friction rub this is an inflammatory disease of the pericardium, which causes the membranes to become sticky, producing friction when the heart beats or when the patient breathes. -Pericarditis How does pericardial friction rub sound? -it is a scratching, grating, high-frequency sound that is heard in both systole and diastole. it is best heard with the diaphragm of the stethoscope at the left lower sternal border What are non-cardiac murmurs related to pregnancy, hyperthyroidism, exercise, and anemia called? (it is normally heard with systole in the pulmonic precordial area) -innocent (or functional) murmurs
