THE HEART
The heart is a cone shaped
muscular organ
It is normally placed on the left
side of the chest and is of the
size of a closed fist
The heart has 4 cavities
- 2 atria
- 2 ventricles
HOW DOES THE HEART WORK?
‘Pacemaker of the heart’
(shown as 1 in the picture)
Weak electrical activity starts
from the Pacemaker
Electrical activity travels along
a certain path (shown in red)
This stimulates all the parts of
the heart, thereby causing the
entire heart to contract and
relax alternatively
Contraction is called as
‘Systole’. Blood is pumped
out of the heart in this
phase.
SYSTOLE
Relaxation is called as
‘Diastole’. Blood is
collected in the heart in
this phase.
DIASTOLE
HDL
LD L
Normal blood vessel
Deposition of
‘bad cholesterol’
Increased deposition
of ‘bad cholesterol’
This is known as atherosclerosis
WARNING SYMPTOMS...
•Difficulty in breathing
•Chest Pain
•Blue Discoloration
•Black out
•Swelling of the body,
especially of the feet
•Awareness of heart beats
•Cough
•Coughing out blood
•Fatigue
(Dysnpnoea)
(Angina)
(Cyanosis)
(Syncope)
(Edema)
(Palpitation)
(Hemoptysis)
HOW TO KNOW OF HEART DISEASE?
•BP measurement
•Blood cholesterol measurements
•Blood sugar measurements
•E C G
•Echocardiogram / Doppler
•T M T / Stress Test
•X-ray
•Angiography
E C G (ELECTROCARDIOGRAM)
An electrocardiogram
(ECG) is a recording of
the heart's electrical
activity as a graph
or series of wave lines on
a moving strip of paper.
This gives the doctor
important information
about the heart.
POSITION OF ECG LEADS
6 or 12 E C G
leads are placed
on the chest
to obtain the ECG
AN E C G LOOKS LIKE THIS...
HOLTER MONITORING
A Holter monitor is a portable
ECG that monitors the electrical
activity of a freely moving
patient’s heart for one to
five days, 24 hours around
the clock
ECHOCARDIOGRAPHY
An Echocardiogram
uses sound waves to
image the heart
Echo is used to examine
the -
• size,
• shape, and
• motion of the heart,
It is useful to diagnose
abnormalities of the
heart valves and to
assess heart’s function
TMT
(TREAD MILL TEST / STRESS TEST)
An ECG performed while the
patient exercises in a controlled
manner on a treadmill or
stationary bicycle at varied
speeds and elevations.
This test helps detect heart
irregularities, disease and
damage.
The outcome of T M T is similar
to the E C G
SCAN
Depending on the precision required
the following scans can be
performed
• X Ray
Least Precise
• CT Scan
• MRI Scan
• Spect Thallium Scan
Most Precise
All of these are painless procedures
wherein X rays are taken
An X-ray shows
•The size of the heart
and arteries
•The condition of the
lungs
•The condition of
surrounding structures

their health to gain wealth….
….In later life, people give
up their wealth to regain some
of their health.”
