Table 2 The patients' diagnoses and findings on auscultation. shows the patients relevant cardiac diagnoses, and the findings on auscultation as reported by two cardiologists.

Day 1:Patient no 1 (1)

Mitral valve insufficiency, possible low grade aortic sclerosis

Holosystolic, rough high frequency, grade 3/6, max intensity in the fourth left intercostal space in the medioclavicular line with radiation to the left axilla. 2^nd heart sound (S2) preserved, no constant splitting of S2. S3 not present.

Patient no 2 (2)

Aortic stenosis

Holosystolic rough murmur grade 4/6, loudest at the apex. Radiation to the left axilla and the carotid arteries. S2 weakened.

Patient no 3 (3)

Control patient without cardiac murmurs

-

Patient no 4 (4)

Aortic insufficiency

High frequency diastolic murmur distinct at the apex.

Day 2:Patient no 1 (1)

Same as day 1

Same as day 1.

Patient no 2 (5)

Control without murmur

-

Patient no 3 (6)

VSD

Holosystolic ejection sound grade 3/6, loudest at the apex. No radiation. S3 present.

Patient no 4 (7)

Mitral valve insufficiency and aortic sclerosis

Holosystolic ejection sound grade 4/6. loudest at the apex, radiation to the left axilla and the carotid artery. S3 absent.

Day 3:Patient nr 1 (8)

St. Jude prosthetic valve in mitral position, paravalvular leakage

Holosystolic rough murmur grade 2, loudest in the left axilla.

Patient nr 2 (9)

Control without murmurs

-

Patient no 3 (10)

Aortic stenosis

Crescendo/decrescendo quincking systolic murmur grade 3/6, loudest parasternally at the right second intercostal space. Radiation to the left axilla and to the carotid arteries.
