What is the function of the heart answer?
The heart is an organ that beats continuously to act as a pump for the transport of blood, which carries other substances with it. The heart pumps the deoxygenated blood to the lungs for oxygenation and receives oxygenated blood from the lungs. It pumps the oxygenated blood to different parts of the body.
How long can you stay on beta blockers?
Guidelines recommend beta blocker therapy for three years, but that may not be necessary. Beta blockers work by blocking the effects of the hormone epinephrine, also called adrenaline. Taking beta blockers reduces your heart rate and blood pressure. This eases the workload on your heart and improves blood flow.
What are the 4 parts of the heart?
Heart Chambers, Valves, Vessels, Wall and Conduction System The heart is made up of four chambers. The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle). Muscular walls, called septa or septum, divide the heart into two sides.

Chambers of the Heart The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.

What controls the heart’s electrical system?
The SA node (called the pacemaker of the heart) sends out an electrical impulse. The upper heart chambers (atria) contract. The lower heart chambers (ventricles) contract or pump. The SA node sends another signal to the atria to contract, which starts the cycle over again.
Can stress cause an irregular heartbeat?
Stress can contribute to heart rhythm disorders (arrhythmias) such as atrial fibrillation. Some studies suggest that stress and mental health issues may cause your atrial fibrillation symptoms to worsen.
What foods are good for irregular heartbeat?

- Coronary artery disease.
- Electrolyte imbalances in your blood (such as sodium or potassium).
- Changes in your heart muscle.
- Injury from a heart attack.
- Healing process after heart surgery.
- Irregular heart rhythms can also occur in “normal, healthy” hearts.
What are the important parts of the heart?
What Are the Parts of the Heart?
- The two bottom chambers are the right ventricle and the left ventricle. These pump blood out of the heart. A wall called the interventricular septum is between the two ventricles.
- The two top chambers are the right atrium and the left atrium. They receive the blood entering the heart.
What causes a heart attack?
A heart attack occurs when one or more of your coronary arteries becomes blocked. Over time, a buildup of fatty deposits, including cholesterol, form substances called plaques, which can narrow the arteries (atherosclerosis). This condition, called coronary artery disease, causes most heart attacks.

- Implantable Cardioverter Defibrillator (ICD)
- Medical Management.
- Pacemaker Implantation.
- Transesophageal Echocardiogram.
- Heart Surgery.
What is heart and its function and structure?
The heart works as two pumps, one on the right and one on the left, working simultaneously. Blood flows from the right atrium to the right ventricle, and then is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the left atrium, then to the left ventricle.
Why is the heart important?

Dronedarone was the best tolerated of the antiarrhythmic drugs, with the lowest rates of severe adverse events and a significant reduction in the risk of stroke. It is our practice to use propafenone, flecainide, sotalol, and dronedarone as first-line therapies in patients without structural heart disease (Table 4).
