Definition
| the closure of the atrioventricular valves (AV) TRICUSPID AND MITRAL VALVES. This sounds like “LUB”. |

|
Term
|
Definition
| the closure of the semilunar valves (SL) AORTIC AND PULMONIC VALVES. This sounds like “DUB”. |
|

Definition
| Aortic and pulmonic valves closing asynchronously |
|
|
Term
|
Definition
| includes the aortic and pulmonic areas, and S2 will be loudest at the base. Aortic and pulmonic murmurs are heard best at the base with the patient leaning forward and sitting up with the diaphragm of the stethoscope. |

Term
|
Definition
| includes the tricuspid and mitral areas, and S1 will be loudest at the apex. S3 and S4 along with mitral stenosis murmurs will be heard best at this position with the patient lying on their left side with the bell of the stethoscope. |

Term
|
Definition
| if the patient is on a bedside monitor the r-wave of the QRS complex will correlate with the sound of S1. |

|
Term
| S3 and S4 are heard best: |
|
Definition
| at the apex of the heart with the bell of the stethoscope while the patient is on their left side. |
|
|
Term
| S3: heard after S2 and sounds like “LUB-DUB-TA” |
|
Definition
| Caused by vibrations of ventricle filling from a resistant ventricle due to fluid volume overload or heart failure. |
|
|
Term
| S4: heard before S1 and sounds like “TA-LUB-DUB” |
|
Definition
| Caused by ventricle resistance from an atrial “kick” during presystole (hypertrophic left ventricle) |
|
|
Term
|
Definition
| blowing/swooshing noise from blood turbulence in the chambers of the heart (wall defect) or valve problem (stenosis or regurgitation) |
