It describes the heart's location, chambers, valves, blood supply, conduction system, cardiac cycle, and normal functioning. Assessment methods covered include vital signs, heart sounds, ECG, echocardiography, nuclear imaging scans, and diagnostic tests like chest x-rays. Nurses' responsibilities in preparing patients and monitoring them during tests are also outlined.

1. HEART
Muscular organ located in centre of thorax.
It weights approx 300gram.
Heart pump blood to tissues ,supplying them oxygen and other nutrients by
process of contraction and relaxation.

CARDIOVASCULAR
SYSTEM

2. INTRODUCTION
 CARDIOVASCULAR DISEASE IS ONE OF MOST
PREVALANT DISEASE NOW IN THE WORLD.
 NURSES, BECAUSE OF THE INCREASE MUST BE
CAPABLE OF ASSESSING CARDIOVASCULAR
SYSTEM AND SHOULD BE ABLE TO PROVIDE
IMMEDIATE CARE.

3. ANATOMY AND PHYSIOLOGIC
OVERVIEW OF HEART
Hollow muscular organ
located in the centre of
thorax.
Weight aprox 300g and
10cm long(size of owner’s
fist)
Heart pump blood to
tissues ,supplying the
oxygen and other nutrients
by process of rhythmic
contraction and relaxation
of heart.

5. POSITION
 It lies in thoracic cavity in
the mediastinum.
 It lies obliquely a little
more left than to right
 It presents a apex (below)
at the 5th intercostal space
and base (above)at the
level of 2nd intercostal
space above.

6. ANATOMY OF HEART
 It is composed of three layers
INNERMOST LAYER- ENDOCARDIUM
MIDDLE LAYER - MYOCARDIUM
OUTERMOST LAYER- PERICARDIUM.
 PERICARDIUM has two layer –Visceral pericardium
- Parietal pericardium
space between this layer is pericardial space which
contain 30ml of fluid which lubricates the surface of
heart and prevents frictional rub.

8. Chambers of heart
 RIGHT ATRIUM – Receives blood from the veins and
pumps into the right ventricle.
 RIGHT VENTRICLE – Receives blood from right atrium
and pump it to lungs oxygenation take place.
 LEFT ARTIUM –Receives oxygenated blood from lungs
and pump it left ventricle.
 LEFT VENTRICLE – Receives blood from left atrium
and pumps oxygenated blood to rest of body.

10. HEART VALVES
 Heart valves ensure a unidirectional flow of blood
through heart and prevent back flow of blood.
 There are two types of valves :
- ATRIOVENTRICULAR VALVE : Seperates the atria
from ventricle i.e
. TRICUSPID VALVE : Seperates the right atria from
right ventricle.
. MITRAL VALVE:Seperates between left atria and left
ventricle.

11. SEMILUNAR VALVES: Composed of three half-moon
leaflets.
Two types :
Pulmonary valve : located between the right
ventricle and pulmonary artery.
Aortic valve: located between left ventricle and the
aorta.

13. BLOOD SUPPLY TO THE HEART
 ARTERIAL SUPPLY: Arterial blood supply through right
and left coronary arteries.
 VENOUS DRAINAGE : Several small vein join to form
coronary sinus which opens to right atrium finally pass to
heart chamber through venous channels i.e superior vena
cava and inferior vena cava.

14. Coronary Arteries

15. PHYSILOGY OF HEART
 Conduction system of heart is controlled intrinsic system
where cardiac muscle is automatically stimulated without
any external stimulation.
 Specialised small group neuromuscular cells in the
myocardium initiate and conduct impulses causing
synchronised contraction of heart.
 SA node (pacemaker of heart) initiates impulses which
reach AV node via atria. Delay in electrical impulses to
reach to AV node takes 0.1 sec to pass through into the
ventricles.

16. •Contd...
 Atrio ventricular bundle(bundle of his ), a mass
specialised fibre which originate from AV node cross
the fibrous ring that separates atria and ventricles.
 At the end of ventricular septum; it divides into right
and left bundle branches and ventricular myocardium
branches break into fine fibre called purkinje fibres.
 AV bundle and purkinje fibre convey electrical
impulses from AV node to apex of the myocardium
causing ventricular contraction pumping blood into
pulmonary artery and aorta

18. BLOOD SUPPLY THROUGH THE HEART

19. NERVE SUPPLY TO THE HEART
 Influenced by autonomic nerve originating in the
cardiovascular centre in medulla oblongata.
 Vagus nerve (parasympathetic ) supply mainly SA and AV
node and atrial muscle.
 Sympathetic nerve supply the SA and AV node and
myocardium of atria and ventricle.

21. CARDIAC CYCLE
Cardiac cycle is series of events in which
the heart act as pump to maintain constant
circulation of blood throughout the body.
 During each cycle (0.8sec);the heart
undergoes a period of contraction
(systole) and period of relaxation
(diastole).

22. STAGES OF CARDIAC CYCLE
The normal number of caridac cycle per
mintute range from 60 to 80.
Taking 74 per min as example , the cycle of
events consists of :
ATRIAL SYSTOLE
VENTRICULAR SYSTOLE
COMPLETE CARDIAC DIASTOLE

23. ATRIAL SYSTOLE
 Superior vena cava and inferior vena cava bring
deoxygenated blood into right atrium, same time 4
pulmonary veins bring oxygenated blood into left
atrium.
 SA nodes triggers which causes a wave contraction
that spreads through both atria , which empty atria
and completes ventricular filling.
Atrial systole last for 0.1 sec.

24. VENTICULAR SYSTOLE
 When the electrical impulses reach AV node, the delay
in AV transmission will lag behind the electrical
impulses for a fraction of a sec allowing atria to finish
emptying into ventricles before ventricular
contraction.
 Now AV node creates its own impulses quickly and
spreads to ventricular muscle through bundle of his
and purkinje fibres creating contraction in the apex of
the heart and across the wall of ventricles pumping
blood into pulmonary artery and aorta.
 Ventricular systole last for 0.3 sec.

25. COMPLETE CARDIAC DIASTOLE
During this time myocardium prepares for the next
heart beat and atria refill in preparation for the next
cycle.
Complete cardiac diastole will last for a period of 0.4
sec.

27. HEART SOUNDS
 During the action of heart due passive closing of the
valves mainly TWO normal heart sounds are heard:
‘DUP’ sound ,which is long and dull sound is due
to the closing of atrioventricular valves and
contraction of ventricles.
‘LUB’ sound ,which is short and sharp is due to the
closing of aortic and pulmonary valves.

29. ELECTRICAL CHANGES IN THE HEART
 Electrical activity is detected by placing the electrodes to
the chest and traced on a paper called as
electrocardiogram and the apparatus used is called as
electrocardiograph
 The normal ECG waves are named as:

30.  P wave: arise when the impulses from SA nodes
sweeps atria.
 QRS complex: represents the rapid spread of
impulses from AV node through the AV bundle and
purkinje fibres and electrical activity of ventricular
muscles.
 T wave: represents the relaxation of ventricular
muscles.
ECG originating from SA node is known as sinus rhythm

31. CARDIAC OUTPUT
 Cardiac output refers to amount of blood pumped by
each ventricle during a given period.
 NORMAL CARDIAC OUTPUT IN ADULT IS 5LITRES
PER MIN.
 CARDIAC OUTPUT =STROKE VOLUME X HEART RATE
 Stroke volume is the amount of blood ejected per heart
beat.
 Average stroke volume = 70 ml
 Heart rate = 60 to 80 beats per minute.

33. DIAGNOSTIC STUDIES IN CVS
 Diagnostic procedures are mainly classified into :
INVASIVE PROCEDURES
NON INVASIVE PROCEDURES
INVASIVE PROCEDURES

- potent coronary vasodilator.
-It block the cellular reuptake of adenosine thereby
increasing blood and tissue concentration of
adenosine.
In normal coronary arteries dipyridamole increases
blood flow 3 to 4 times whereas in stenosed arteries;
blood flow will be significantly reduced(70%).
