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.

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
