(Heart sound) - stethoscope The heart sounds we can hear with a stethoscopeare caused by the closing lub-dup, lub-dup,of the valves. The sound pattern islub-duplub-dup, lub-dup,lub-dup. -lub: The first heart sound(lub) is created by AV valve the recoil of bloodagainst the closed ventricle AV valves. The second sound -dup: (dup) is the recoilof blood against the semilunar valve semilunar valves. ventricle - valve heart murmur 17. (cardiac cycle) -cardiac cycle: - systole - diastole -cardiac output: ventricle cardiac out put (vol/min) = heart rate (no./min) X stroke volume (vol/no.)5.25 L/min =70 beat/minX75 ml/beat 18.
