Mitral Regurgitation (Mild) Case Study: 1
S1 S.Mur S2 dias.mur S1 S2
S1 pansys.murm S2 diastole
Single Heart beat. Pansystolic murmur.
Systolic Murmur Frequency Spectrum- very wide 60 to 230 Hz.
Clearly abnormal. Pansystolic -abnormal.
Diastolic Murmur Frequency Spectrum. 70 to 180 Hz spectrum.
Any diastolic murmur is abnormal.
Murmur intensity is low - shows no abnormality. But frequency is high
(146 Hz) and bandwidth is high =2*63 Hz. Duration is 97%.
Clearly abnormal on 3 accounts out of 4.
Energy Signature of One Heart Beat - Murmurs are weak and almost
invisible on the energy signature.
S1 is very weak (soft).
Energy Signature - Power vs. Time plot. S1 is soft.
Murmur instantaneous frequency -120 to 220 Hz range.
Grade 1 pansystolic murmur. Clearly abnormal. Weak diastolic murmur as well.
S1 is soft.
Heart Sound was taken from the Ears On Auscultation Program
