Term
| Use of the stethoscope bell |
|
Definition
| For hearing S3 and S4 heart sounds (lower pitched). Press lightly on steth. |
|
|
Term
| Use of the stethoscope diaphragm |
|
Definition
| For hearing high pitched sounds (S1 and S2). Press down firmly on stethoscope. |
|
|
Term
| Heart sound related to carotid pulse |
|
Definition
| Associated with S1 and QRS complex. |
|
|
Term
| Location of semilunar valves |
|
Definition

|
Term
| Location of tricuspid and mitral valves |
|
Definition
|
|
Term
|
Definition
| Caused by stenotic aortic and/or pulmonary valves. Causes murmur at base of heart. Pressure difference between valve and ventricle is larger than normal (pressure difference goes from small to large to small, creates sudden peak in noise due to sudden turbulent flow, also called crescendo decrescendo murmur between S1 and S2. |
|
|
Term
|
Definition
| Leaky AV valves, can be heard at apex of heart, creates turbulent flow of blood from tricuspid and mitral valves back into atria. Results in slow, constant murmur at apex of heart in between S1 and S2. |
|
|
Term
|
Definition
| Ventricular gallop that occurs immediately after S2. Beat after S2 can be S3, S2 split (pulmonary valve closes after aortic), or other pathological causes. |
|
|
Term
|
Definition
| Occurs right before S1 sound, sounds like S1 is split. |
|
|
Term
|
Definition
| Leaky aortic valve in diastole leads to gradual lessening of pressure in aortic valve. Leads to gradually decreasing murmer after closure of aortic valve (S2). |
