The Anatomy of The Human Heart

Each day, your heart pumps nearly 2,000 gallons of blood. Over the span of an average lifetime, it will beat over 3 billion times. It is slightly bigger than a clenched fist, and is located behind the sternum, between the lungs.

This article will explore your heart’s anatomy. We’ll describe its exterior, including the arteries and veins that supply blood to the muscle. We’ll also describe the organ’s interior, including the chambers, valves, and blood flow. Lastly, you’ll learn how its electrical system helps ensure its proper function.

Exterior Of The Organ

A system of coronary arteries and blood vessels supply the surface of the organ with oxygenated blood. If anything obstructs this blood supply, the muscle can become injured. This is known as a heart attack.

The organ receives oxygen-depleted blood from the rest of your body through the inferior and superior vena cavae. Blood flows into the right side of your heart before moving to your lungs through the pulmonary arteries. It picks up oxygen from your lungs and flows into the left side of the organ. Enriched with oxygen (by your lungs), blood leaves the left ventricle and travels through the aorta; some of it passes into the coronary arteries and supplies blood to the surface of your heart.

Interior Of The Organ

There are four chambers within your heart: two upper chambers called atria and two lower chambers called ventricles. The left and right sides are separated by a wall called the septum. A series of four one-way valves help control the flow of blood as it moves through the organ.

As noted earlier, blood flows into the right atrium from the vena cavae. It then passes through the tricuspid valve as it moves into the right ventricle. From there, it flows through the pulmonary valve into the lungs before flowing into left atrium. The mitral valve manages the flow of blood between the left atrium and the left ventricle. The left ventricle empties as blood moves through the aortic valve into the aorta. This entire process is possible due to contractions triggered by your heart’s electrical system.

The Electrical System

A group of cells within your right atrium form the sinoatrial node. This node produces electrical impulses that spread across the surface of each chamber, causing them to contract. The signals begin by spreading through the atria. As the atria contract, the blood within is forced through the corresponding valves into the ventricles.

The electrical impulses then arrive at another group of cells called the atrioventricular (AV) node. This node is located near the tricuspid valve (between the right atrium and right ventricle. The signals pause at the AV node while the ventricles fill with blood. Once they have filled, the signals are released in order to spread throughout the lower chambers, causing them to constrictt and push blood outward.

Your heart works tirelessly to pump blood between the chambers and your lungs, and out to the rest of your body. Over time, problems such as mitral valve disease, atrial fibrillation, and clogged coronary arteries can prevent the organ from performing its job. If such problems emerge, speak with your physician regarding an appropriate form of treatment.

Written by the Editors at Weight Loss Buddy Press in colaboration with Hans A. Diehl, DrHSc, MPH, FACN, CNS It is well known that about two-thirds of the U.S. population is either overweight or obese. They are directly correlated with our high fat diet, inadequate amounts of exercise, smoking, high intake of caffeine, and high amounts of stress coupled with insufficient support.Hoping to address this alarming situation , more than 20 years ago, cardiovascular epidemiologist Hans A. Diehl, DrHSc, MPH, created the Coronary Health Improvement Project (CHIP). Since then, this 40-hour community-based lifestyle intervention program has helped more than 40,000 people rediscover their health by preventing, arresting and reversing their diseases.

Who is the typical CHIP participant? Generally, CHIP participants are over the age of 40. Most are between the ages of 50 and 59. 10% report having heart disease  27% have elevated blood sugar  42% are overweight  49% show evidence of hypertension  60% are obese  89% are cholesterol above 160mg% Over the course of the program, strict adherents are likely to experience significant clinical improvements such as the following:  Serum cholesterol reduction average 15 ?20%  Average weight loss of six pounds  In about half of the participants with type 11 diabetes, a dramatic reduction in need for insulin and hypoglycemic agents  Lowering of high blood pressure levels  Diminishing of angina 

Atrial Fibrillation – What Are the Risks?

A lot of people misunderstand the causes and potential side effects of atrial fibrillation (commonly known as Afib). Even among those who have coped with the disorder for years, there is a mistaken belief that the condition is harmless. In truth, it’s not. It can lead to stroke, heart failure, and other consequences.

To review, Afib is characterized as an erratic discharge of rapid electrical impulses that spread across your heart’s atria (i.e. the two upper chambers). Rather than contracting in sync with your heart’s ventricles (i.e. the two lower chambers), the atria flutter – or fibrillate. In some cases, the disorder causes no noticeable symptoms. In other cases, the patient might be at risk of experiencing medical events that can be life-threatening.

In this article, we’ll explore some of the dangerous risks involved with not addressing atrial fibrillation. We’ll also detai an operation known as the maze procedure that a growing number of surgeons are using to help solve the problem.

The Risk Of Stroke

A stroke is the result of blood clots that clog one of the arteries in the brain. Clots rarely form in these arteries; instead, they form elsewhere, break away, and travel along your bloodstream.

Atrial fibrillation can result in the pooling of blood with one or both of your atria. As a result, the blood begins to clot. If the clots simply remain within your atria, they pose little danger. However, they can break away and move through your ventricles on their way to the aorta.

Blood travels from your heart through the aorta and onward to your brain. The clots and then travel through your bloodstream until they reach and clog a major artery. That produces a stroke. Common symptoms of a stroke can include partial paralysis, eye problems, and difficulty remembering things.

The Risk Of Heart Failure

Heart failure occurs when the heart muscle is overworked to the point of exhaustion. This can happen for a number of reasons, including coronary artery disease, diabetes, and of course, atrial fibrillation. In the latter case, the rapid electrical signals cause the atria to flutter so quickly that they eventually wear themselves out and weaken the heart. That reduces your heart’s ability to pump blood effectively throughout your body. As a result, the heart muscle becomes enlarged and is further weakened.

Secondary Side Effects

The reduced ability of your heart muscle to pump oxygen-rich blood to your tissue and organs can produce a number of secondary side effects. For example, your lower extremities (i.e. ankles and feet) may start to swell. Moreover, it’s not uncommon for the abdomen to also begin expanding.

Depending on the severity of the Afib-induced heart failure, you may experience a level of organ damage. This is due to your organs not receiving a sufficient supply of oxygen-rich blood.

You might also develop a persistent cough and shortness of breath if the condition produces excess fluid around your lungs. Unless Afib is resolved, these side effects can become permanent.

Maze Procedure To Resolve Afib

The most common method for addressing atrial fibrillation is the maze procedure. This is an operation during which your surgeon will create incisions or use catheter ablation to produce a maze of scar tissue across the surface of your atria. Scar tissue cannot conduct electricity. By designing this path, your surgeon can reroute the erratic patterns of the electric impulses. In effect, the surgeon is able to guide the signals along a defined path, thereby eliminating the fluttering and restoring a uniform rhythm for your heartbeat.

Atrial fibrillation can remain undetected for years. This is one of the reasons many patients never seek treatment. The problem is, the conditin can be very risky, depending on the severity of the case. If you suspect you have Afib, consult your doctor regarding whether the maze procedure is an appropriate solution for your circumstances.

Understanding Atrial Fibrillation And Its Effects

Atrial fibrillation (also known as AF and AFib) is a condition in which your heart’s atria (the two upper chambers) flutter, or fibrillate. This causes an arrhythmia. To understand how the problem occurs, it’s important to appreciate how your heart functions.

The organ has four chambers: two atria (upper chambers) and two ventricles (lower chambers). Within the right atrium, a group of cells known as the sinoatrial node generates electrical impulses. These impulses spread throughout your atria, causing them to contract. As the contractions cause blood to move from the atria into the ventricles, the impulses travel to the atrioventricular node. This is another group of cells that sits between the ventricles and atria. Once the ventricles fill with blood, the impulses move from the atrioventricular node through the ventricles, causing them to contract.

In AFib, the electrical signals do not start at the sinoatrial node; they start elsewhere. Instead of following the uniform path outlined above, the signals are distributed erratically though your atria. That causes them to flutter. Moreover, the impulses overwhlen the atrioventricular node, which, in turn is unable to transmit the signals to the ventricles at the same pace they recieve them. The result is that your atria will fibrillate and your ventricles will beat faster than normal, but your heart’s rhythm will be completely disorganized.

How It Impacts Your Life

Because your ventricles receive a barrage of electrical impulses, they contract more quickly than they should. They do so before they can fill completely with blood. As a result, when they contract, less blood is sent throughout your body. You may notice a shortness of breath, disorientation and exhaustion after even light physical effort.

You’ll also feel your heart beating more quickly and harder than is normal. This is due to the organ working harder to send a sufficient amount of oxygen-rich blood throughout your body.

The most serious complications of atrial fibrillation are stroke and heart failure. Stroke can occur as the result of blood clots that form within the atria, especially the left atrium. If one of the clots moves from the atrium, it can reach a carotid artery and cause a stroke. Heart failure can occur due to your ventricles beating too quickly as the result of receiving a stream of electrical impulses.

How Atrial Fibrillation Is Treated

Atrial fibrillation is not always dangerous. Mild cases may be treated with anticoagulants that will prevent clotting in the atria. However, severe cases are usually best addressed with surgery. Many years ago, open chest surgery was necessary in order for the surgical team to access the heart. Today, AFib can be resolved through a minimally invasive maze procedure.

During maze surgery, a surgeon will create a maze of scar tissue on the atria. This scar tissue does not conduct electricity, so the signals are forced to detour along the maze created by the surgeon. This helps to control the impulses and thereby, regulate the heartbeat. If you suffer from AF, ask your doctor whether a maze procedure is a viable solution.
