#CARDIAC MURMUR
The abnormal heart sound produced during cardiac
cycle is called cardiac murmur.
#CARDIAC OUTPUT
`The quantity or amount of blood that pumped out
from each ventricle per minute’
CO = SV × HR
=70ml × 72
=5042ml
=5.042L
It is 10-20% less in women
`The quantity or volume of blood that pumped out from
each ventricle per beat is called stroke volume’
SV = EDV-ESV
=110ml-50ml
=60ml
END DIASTOLIC VOLUME
`The volume of blood that will remain in each ventricle after
ventricular diastole’
EDV=110-120ml
END SYSTOLIC VOLUME
`The volume of blood that will remain in each ventricle
after ventricular systole’
ESV=40-50ml
`It is the difference between systolic pressure & diastolic
pressure’
PP = Systolic-Diastolic
=(120-80)mmHg
=40mmHg
MEAN PRESSURE
Mean pressure is theDiastolic pressure+ 1/3 of pulse pressure
= 80mmHg +40/3mmHg
= 80mmHg + 13mmHg
= 93mmHg
`The rhythmic expansion of the arterial wall due to
pressure change during systole & diastole’
TYPES:* Radial pulse
* Brachial pulse
* Axillary pulse
* Femoral pulse
* Facial pulse
* Popliteal pulse
* Arterial dorsallis pedis pulse
`The cardiac events that occur from the beginning of
the one heart beat to beginning of the next are called
cardiac cycle’
►Systole:The contractile phase of the heart
►DIASTOLE:The relaxation phase of the heart
ECG
(ELECTROCARDIOGRAPHY)
`ECG is the graphical representation of the
electrical change of the heart during cardiac
cycle’
CARDIAC CYCLE TIME
0.8 SECOND
#IN ATRIUM
* Atrial systole:0.3 sec
* Atrial diastole:0.5 sec
#IN VENTRICLE
* Ventricular systole:0.1sec
* Ventricular diastole:0.7sec
CIRCULATION
A process of the flow of blood & lymph through a close system
with vessel
TYPES:*Pulmonary circulation
*systemic/greater circulation
HEART MUSCLE
