Aorta - the largest artery in the body, is
almost the diameter of a garden hose.
Capillaries - are so small that it takes ten of
them to equal the thickness of a human hair.
Troponin - Protein that is released into the
bloodstream when a heart attack occurs.

Cardiac arrest is what happens when the
heart stops pumping blood effectively
enough to get oxygen to the tissues of the
body.
Heart attack occurs when the heart does not
get enough oxygen and as a result some of
the heart muscles die. (Myocardial
infarction)

Arrhythmia -Irregular heartbeat at any speed.
Tachycardia / Tachyarrhythmia - (greek word for “fast”, tachys)
– condition for any rate greater than 100 beats a minute
Bradycardia / Bradyarrhythmia - condition of a heart that is
pumping too slow, which is defined as any rate less than 60
beats per minute.

When the atria contract, the ventricles are at
rest so that they can receive the blood
pumped into them from the atria.
When the atria are at rest then the ventricles
contract.
A heartbeat consists of one contraction
phase of the ventricles, called the systole
and one resting phase called diastole.

During the systole, blood is being forced
under pressure out of the ventricles and into
the arterial system. The arteries dilate. And
this dilation is felt as a pulse at certain
points in the body.
The pressure of the blood against the
arterial walls is called blood pressure.

The pressure of the systolic and diastole is
measured and expressed as two numbers by
an instrument called sphygmomanometer.
Systolic pressure is the first number.
It is higher because the ventricles contract
during the phase.
Diastole pressure, 2nd number, is lower
because it is a measure of pressure during the
ventricular resting phase.

A normal blood pressure measurement
would range from 100/60 to 120/80 mm
Hg. (milli meters mercury)
High blood pressure is called hypertension.
LBP is called hypotension.
Hypertension – 140/90
Hypotension – 90/60
Optimum - 120/80

The case is reported of a 37-year-old woman who suffered a heart attack during labor.
Except for smoking, there was nothing in her medical history indicating increased risk
for heart disease. Just over 10 hours after she was admitted to the hospital for labor,
she experienced what was thought to be heartburn. She also experienced vomiting
episodes and a short-term drop in blood pressure. Her chest pain disappeared and
she delivered a baby boy. Two days following delivery, severe heartburn returned. The
pain resolved in one hour. An electrocardiogram performed later that day showed she
had suffered a heart attack a few days earlier, probably during labor, and that the
second episode was post infarction angina. She was treated and discharged shortly
thereafter. Although heart attacks during pregnancy are rare, a number of cases have
been reported. Smoking appears to be the greatest risk factor in younger women.
Coronary artery spasms may be the cause of many of these attacks. (Consumer
