2. 1.PACEMAKER DYSFUNCTION1.PACEMAKER DYSFUNCTION
Pacemaker:Pacemaker:
The Cells that create these rhythmical
impulses are called pacemaker cells,
and they directly control the heartbeat rate
The electrical impulses from the heart
muscle that cause your heart to contract
usually begins in the sinoatrial node,
located on the top of the right side of the
heart.
The sinoatrial node is called the Heart ofHeart of
Heart.Heart.

3. Many pacemaker disorders do not cause symptoms.
If there are symptoms, they may include:
1.A consistently slow heart rate
2.Fainting, if the heart rate becomes very slow or
if the heart is slow in returning to a normal rhythm
after a period of rapid beating
3.Periods of slow heartbeats
1.An under active thyroid
gland (hypothyroidism)
2.Certain drugs
3.Unknown causes.
In this case, the disorder is
called sick sinus syndrome
CAUSESCAUSES
Implanting a mechanical pacemaker.
This is a device, run by a battery, about the size
of a matchbox that helps the heart beat regularly

4. 2.MAYOCARDIAL INFRACTION2.MAYOCARDIAL INFRACTION
Myocardial infarction (MI) or commonly known as heart attack,
results from the interruption of blood supply to a part of the heart
muscles causing heart cells to die.

5. Typical symptoms of acute myocardial infarction include sudden chest pain
(typically radiating to the left arm or left side of the neck), shortness of breath,
nausea, vomiting, palpitations, sweating and anxiety.
Women may experience fewer typical symptoms than men, most commonly
shortness of breath, weakness, a feeling of indigestion, and fatigue.
A sizeable proportion of myocardial infarctions (22–64%) are "silent", that is
without chest pain or other symptoms.

Artery:Artery:
They are the blood vessels that carry blood
away from the heart to the all parts of the
body.
Arterial thickening leads
to the blockage of blood
