Heart

harvard, stanford, city colleges,

I looked it up in Wikipedia and I think you're looking for afterload.

ligamentum arteriosum

Heart is myogenic , it can pump by itself without help of brain .

1. Arial diastole (relax)

- atrial muscle relax , pressure decrease, blood enter atrium

2. Atrail systole (contract)

- atrium pressure increase, blood enter venticle .

3. Ventricular systole

- blood enter ventricle , delay for 0.1s . ventricle pressure increase, semiluna valve open , blood flow into vessels .

4. Ventricular diastole

- ventricle mucle relax , prepare for next cardiac cycle .

The Atrial septum

The wall between the two atriums is called the septum.

Septum

Cardiac Septum

Atrial septum, containing the foramen ovale.

Actually its called the interatrial septum...

The left atrium

yes

the upper chambers of the heart are called the right and left atrium and they are the receiving chambers of the heart

the interventricular septum, it separates the two ventricles

The Heart Within was created in 1957.

It is controlled by an electrical conduction system special to the heart that allows a impulse begun by the sinoatrial node (SA node) to be propagated throughout the cardiac muscle. The heart contracts after stimulation but in an ordered stimulation that allows efficient contraction of the heart. The atrium contract first and then the ventricles after a short pause.

Heave is a precordial impulse that may be felt (palpated) in patients with cardiac or respiratory disease. Precordial impulses are visible or palpable pulsations of the chest wall, which originate from the heart or the great vessels.

The sounds LUB and DUB (also dup) are used to indicate a human heartbeat, with the LUB sound made by the closing of atrioventricular valves, and the DUB by the closing of the exterior or semilunar valves (aortic valves and pulmonary valve).

Intermittent or recurrent sudden increases in heart rate, with a drop in blood pressure, suggest possible supraventricular tachycardia, atrial fibrillation, or some other cardiac dysrhythmia. The sudden increase can be caused by medications(stimulants), stress, or an underlying abnormality of the heart. A elderly patient experiencing this with a drop in blood pressure most likely has some type of underlying cardiac disease, such as coronary artery disease (hardening of the arteries of the heart)that has not been detected or diagnosed yet. The patient should be seen by their physician or a cardiologist. The testing that may be performed include an laboratory studies, EKG, holter monitor, echocardiogram, stress testing, and possibly cardiac catheterization. I have no doubt your father is being treated for his heart problems. It is extremely important he works closely with the family doctor and also the Cardiologist. If you have a good Cardiologist then phone him/her and let them know what is going on. 71 isn't all that old.

The most dangerous complication of a thromboembolus originating in the left side of the heart is a stroke. However, since the left heart gives rise to the aorta and the aorta directly and indirectly feeds all tissues of the body, thromboembolism from the left heart can affect any organ of the body.

it reduces the fluctuation of power station such as in voltage.frequency etc.

Yes, but blood pressure can change quickly. My husband had great readings for his blood pressure and also the best cholesterol readings our doctor ever saw. I had noticed last year my husband was very lethargic and just not himself. Considering he'd had a thyroid operation several years ago I thought his thyroid was out of whack so I made an appointment with the doctor to see if this was the cause. Everything came back normal so our GP sent my husband to an Internist and found my husband had Atrial Fibrillation. This means that the top of his heart is jiggling and out of rhythm and there is a danger that the lower chamber of the heart may well pool blood which will gel and cause clots that could cost him his life. He is now on Warfarin to thin his blood down. This is how quickly our health can change. However, it appears you have a clean bill of health and be sure you eat well, drink lots of water and exercise to keep it that way. When some people realize they have good blood pressure they eat junk food, sit around, don't eat properly or the right things, and don't exercise. The heart is a muscle and you have to exercise it and feed it right.
