CARDIO-VASCULAR SYSTEM – Part 2 Jony Mallik B. Pharmacy; M. Pharmacy

#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 CO = SV × HR =70ml × 72 =70ml × 72 =5042ml =5042ml =5.042L =5.042L It is 10-20% less in women 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= ml END SYSTOLIC VOLUME `The volume of blood that will remain in each ventricle after ventricular systole’ E ESV=40-50ml

`It is the difference between systolic pressure & diastolic pressure’ PP = Systolic-Diastolic =(120-80)mmHg =40mmHg `It is the difference between systolic pressure & diastolic pressure’ PP = Systolic-Diastolic =(120-80)mmHg =40mmHg

MEAN PRESSURE MEAN PRESSURE Mean pressure is the- Diastolic pressure+ 1/3 of pulse pressure Diastolic pressure+ 1/3 of pulse pressure = 80mmHg +40/3mmHg = 80mmHg +40/3mmHg = 80mmHg + 13mmHg = 80mmHg + 13mmHg = 93mmHg = 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 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 ` 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 CARDIAC CYCLE TIME 0.8 SECOND #IN ATRIUM * Atrial systole:0.3 sec * Atrial systole:0.3 sec * Atrial diastole:0.5 sec * Atrial diastole:0.5 sec #IN VENTRICLE * Ventricular systole:0.1sec * Ventricular systole:0.1sec * Ventricular diastole:0.7sec * 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
