Cardiovascular Health

My uncle had 8 heart attacks before his last one that killed him.

This could vary with symptoms. If it is just your forearm/wrist it could be carpal tunnel, arthritic related, tendonitis - these would also cause it to feel weak.

With two Numbers systolic pressure over the diastolic pressure

i am not a doctor but 104 over 60 is an excellent blood pressure for a 38 yr old and and just about any other adult

a child has average up to 10.6 pints of blood in the body

pros: * cheap * abundant * no moral conflicts. (maybe just a little) * more Donors * easy to get hold of cons: * never the right size. * requires close watch on the donar vs host rejection snydrome as the immune system find them really easy to spot. * Ethicly wrong

Cardiac output is the blood volume pushed out by the left ventricle per minute.

Stroke volume is the volume of blood pushed out of the left ventricle per contraction of the heart (each heart beat). So stroke volume into heart rate / minute gives you cardiac output.

Quickclot is a powder which is applied directly to the wound to prevent bleeding. Alternately it can be a quickclot infused gauze. A bandage is then wrapped around the site for protection and/or compression. The wrapper should be placed in the final outside fold of the dressing for easy identification of treatment rendered.

As an individual having had SVT since birth I have grown to understand this as an inexplicable, rapid increase in heart rate. There are possible contributary factors such as high fat diet and alcohol but mine seems to be triggered posturally (when i bend over or jump).

The heart will jump from resting to 200bpm in a blink of an eye and may last for anything from 5 seconds to 60 minutes (for me).

Treatment can be digoxin which cures arhythmias.

Other symptoms of SVT include palor, sweat, shortness of breath and dizzyness. Thought to be a chronic condition although having spoken to several doctors about it, there doesnt seem to be a definite answer as to why it happens.

FROM THE LUNGS

Ans 2:

Veins have valves that cause one-way flow of blood. Muscular contraction squeezes the veins and causes the veins to pump blood back towards the heart.

Deoxygenated blood is carried by veins from the body to the right side of the heart. The right ventricle pumps the deoxygenated blood to the lungs via the pulmonary arteries. Oxygen diffuses into the blood in the lungs, and carbon dioxide diffuses out of the blood into the lungs. After oxygenation, blood is carried to the left side of the heart via the pulmonary veins. The left ventricle pumps the oxygenated blood through the aorta, the largest artery in the body, to the rest of the body. The aorta branches into smaller arteries, which branch into arterioles, which branch into capillaries. At the capillaries, oxgen, nutrients, and certain hormones are delivered to the body cells, and the body cells deliver carbon dioxide, wastes, and certain hormones to the blood. The capillaries then form into venules, then veins, which then deliver the deoxygenated blood to the right side of the heart via the vena cavae, the largest veins in the body. This cycle occurs every second of every day of your life.

An EKG tech works with patients who are in need of an electrocardiogram. Technicians attach leads to the patient and conduct the test. They may perform this task in a doctor's office, a clinic, an ER, in surgery, or any other area of a hospital. Typically, they are part of the cardiac unit or the radiology unit of larger hospitals.

That is considered borderline high blood pressure, however, a one time reading of blood pressure is not enough to make adiagnosis. Some peoples blood pressure goes up just by going to the doctor, called the white coat syndrome. Blood pressure can go up with stress, pain, anxiety, exercise ect...the best thing to do is to take serial readings to get an average. It should average below 140/90 at rest.

During the T-wave the ventricles are repolarizing, preparing for the next beat.

Yes. Oxygen is considered a drug and can raise both blood preasure and heart rate.

Is this symptom has any relation with THYROID gland ?

It is considered a medical abnormality if it is less than

60 (Bradycardia) or more than 100

(Tachycardia) when resting.

Trained athletes tend to have low heart rates, so lower than 60 may be normal if there are no other symptoms and you train regularly.

75 beats per minute would be considered average for a human female when resting.

As the ventricles of the heart contract the pressure in the ventricles rises beyond that of the atria. This pressure differential causes the AV valves to shut.

Varies quite a bit, BUT

1. anytime you experience orthostatic hypotention (light headedness on standing) OR

2. a BP reading of below about 90/50

you should suspect low bp.

A thin inner layer, a muscular middle layer (that gives the vessel its flexibility under pressure from the filling blood), and a fiber-like outer layer that gives the vessel strength to not burst when the heart pumps blood to the body.

According to research the circumstances for one to be considered for coronary stenting are if one has coronary heart disease of some kind or are at risk of having a heart attack. This helps prevent any causes of this procedure happening and can also save lives.

The heart. When the heart pumps blood, it pushes the other blood to move.
