9. cardiovascular auscultation Flashcards
Methods of cardiovascular
examination: (physical examination)
- Inspection (heart, vessels)
- Palpation (heart, vessels)
- Percussion (heart)
- Auscultation (heart)
What instruments are used for the cardiovascular auscultation:
Plessimeter and stethoscope (fonendoskop)
Normal heart sounds:
- heart sounds
Alterations of the cardiac sounds: FRIDA
Frequency, Rhythm, Intensity, Demarcation, Adventitious sounds
Pulse deficit: Physiological or pathological?
Always pathological
Examination of pulse deficit:
Simultaneous auscultation and palpating the pulse.
Explain arrhytmia:
pathological rhythm, often with pulse deficit
Is respiratory arrhytmia slower or faster during expiration?
Slower: vagus effect
Normal intensity of the cardiac sound:
normally strong and even (uniform strength)
Explain pounding heart beat:
increasing of the first and/or second sound (slight variation over different valve areas)
Explain reduced heart sounds:
decreased cardiac output,
pericardial or +/- pleural effusion,
obesity
What is demarcation?
distinctness of the cardiac sounds
what can be heard in cardiomyopathies?
galopp sounds: three
heart sounds can be heard: 1.,2.,3. or 4.,1.,2
what can splitting of the 2. heart sound be caused by?
closure of the aortic and pulmonal valves in different time,
due to cor pulmonale causing increased pulmonary arterial pressure.
Additional or adventitious sounds of the heart:
murmur
