Question | Answer |
---|---|
left semilunar valve separating the left ventricle and the aorta | Aortic valve |
tip of heart pointing down toward the 5th intercostal space | Apex of heart |
broader area of heart's outline located at the 3rd right and left intercostal space | Base of the heart |
the heart's filling phase | Diastole |
tranditional auscultatory area in the 3rd left intercostal space | Erb's point |
occurs with closure of the atrioventricular valves signaling the begining of systole | S1 (first heart sound) |
(atrial gallop) very soft, low-pitched, ventricular filling sound that occurs in late diastole | S4 (fourth heart sound) |
the addition of a 3rd or 4th heart sound makes the rhythm sound like the cadence of a galloping horse | Gallop rhythm |
left AV valve separating the left atria and ventricle | Mitral valve |
area of the chest wall overlying the heart and great vessels | Precordium |
right semilunar valve separating the right ventricle and pulmonary artery | Pulmonic valve |
occurs with closure of the SL valves, aortic and pulmonic, and signals the end of systole | S2 (second heart sound) |
the heart's pumping phase | Systole |
soft, low pitched, ventricular filling sound that occurs in early diastole (gallop) and may be an early sign of heart failure | S3 (third heart sound) |
right AV valve separating the right atria and ventricle | Tricuspid valve |
