Atlas of Auscultation
About:
The Atlas serves as a training tool for healthcare workers and students alike to better prepare for the clinical setting. These clean, low-interference sounds offer a great introduction to real-life auscultation findings. Here you will find our house-made auscultation sounds great for study purposes, as well as an associated-Anki deck for additional practice.
Included:
Clean, low interference auscultation sounds of pathological and non-pathological findings
Supplementary pictures with stethoscope locations for each finding
An Anki deck for learning and spaced-repetition

Adult
Normal Heart Sounds
Aortic Stenosis (Early)
Auscultation: Harsh, crescendo-decrescendo murmur in systole. Note that this murmur is heard early. Radiates to the carotids.
Aortic Stenosis (Late)
Auscultation: Harsh, crescendo-decrescendo murmur in systole. Note that the murmur is heard later in systole. Radiates to the carotids.
Aortic Regurgitation
Auscultation: High-pitched, blowing, decrescendo early diastolic murmur
(Benign) Flow Murmur
Auscultation: Soft, mid-systolic (commonly) varying in intensity and commonly position-dependent
Mitral Regurgitation
Auscultation: Holosystolic murmur. Soft first heart sound. 3rd heart sound may be audible. Radiates to left axilla.
Mitral Stenosis
Auscultation: Delayed decrescendo diastolic murmur
Pulmonic Stenosis
Auscultation: Harsh, crescendo-decrescendo ejection murmur. Prominent S2 splitting.
Atrial Septal Defect
Auscultation: Soft, systolic ejection murmur best heard at the pulmonic area combined with a fixed, wide split of S2.
Ventricular Septal Defect
Auscultation: harsh, holo-systolic ejection murmur best heard at the left lower sternal border area
Pediatrics
Neonate Normal
Pediatric Normal
Cervical Venous Hum
Auscultation: Continuous, low-pitched, low intensity (grade I – III) sound heard best at the supraclavicular fossa (right side greater than left)
Still’s Murmur
Auscultation: Low pitched, mid-systolic, crescendo-decrescendo murmur varying in intensity (usually grade I – III); may radiate to the apex
Atrial Septal Defect
Auscultation: Soft, systolic ejection murmur best heard at the pulmonic area combined with a fixed, wide split of S2.
Patent Ductal Arteriosus
Auscultation: Continuous, machine-like murmur that is loudest at S2 and is best heard at the left infraclavicular fossa.
Hypertrophic Cardiomyopathy
Auscultation: systolic ejection crescendo-decrescendo murmur that is best heart at the left lower sternal border.
