SWEET HEART
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.
Relaxation is called as ‘Diastole’. Blood is collected in the heart in this phase.

Deposition of ‘bad cholesterol’
WARNING SYMPTOMS...
•Difficulty in breathing(Dysnpnoea)•Chest Pain (Angina)•Blue Discoloration (Cyanosis)•Black out (Syncope)•Swelling of the body, especially of the feet (Edema)•Awareness of heart beats(Palpitation)•Cough•Coughing out blood(Hemoptysis)•Fatigue
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
T M T(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
• CT Scan
• MRI Scan
• Spect Thallium Scan
Least Precise
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
