Cardiology Flashcards
What might a midline sternotomy scar indicate?
CABG
Open mitral valvotomy or valve replacement
Aortic valve surgery
Mediastinal surgery
What might a left lateral thoracotomy or inframammary scar indicate?
Closed mitral valvotomy
Predicting valve abnormalities before auscultation: mitral stenosis
Normal pulse/AF
Normal pulse pressure
Undisplaced apex
Predicting valve abnormalities before auscultation: aortic regurgitation
Large volume/bounding pulse
Wide pulse pressure
Displaced apex
Predicting valve abnormalities before auscultation: aortic stenosis
Small volume pulse
Narrow pulse pressure
Undisplaced apex
Predicting valve abnormalities before auscultation: mitral regurgitation
Normal volume
Wide/normal pulse pressure
Displaced apex
Causes of a loud S1
Tachycardia
Short PR interval
Mitral stenosis with a pliable valve
Tricuspid stenosis
Increased flow in high output states
Causes of a soft S1
Bradycardia
Long PR interval
Mitral stenosis with a non-pliable valve
Tricuspid regurgitation
Poor chest wall conduction
Causes of a variable S1
AF
Ventricular ectopic beats
Complete heart block
