Abnormal cardiac arrhythmias or arrhythmias are most commonly caused by atrial fibrillation: atrial fibrillation covers the two largest upper chambers of the heart, and flicker is the medical term used to describe the "tremor" of the affected heart muscles.
Before we take a closer look at atrial fibrillation, we need to familiarize ourselves a little with the structure of the heart to better understand what happens with this condition and how we deal with it.
The heart consists of four chambers; As we said, the two largest chambers, called the atria, rest on two small chambers, called the ventricles, and each atrium is connected to the lower ventricle. The atrium's job is to collect blood after it has passed through the lungs and is then rich in oxygen waiting to be released to the rest of the body. The atrium then contracts to force this blood into the lower ventricle. The ventricle is smaller than the atrium, but much more powerful. When it contracts, it pushes blood under pressure from the heart and around the body.
It is the double contraction of the atria, followed by the ventricles, which forms the typical heartbeat that we hear as a double beat - "duh-dum".
With a-fib, the regular double beat is uncoordinated and this means that the blood is not directed into the ventricles at the right time - the blood literally misses the heartbeat.
The actual cause is usually that the electrical signal that coordinates the heart is disturbed or does not pass through the heart properly to trigger muscle contraction. The disorder is often caused by the drowning of the electrical signal by electrical impulses generated elsewhere by the atria or the pulmonary system. This creates an irregular heart rhythm disorder or a heartbeat, and an episode may take a few moments or an extended period of time, sometimes years, to be recognized.
Fortunately, a-fib is generally not life-threatening, but a number of symptoms can occur and are generally not pleasant - fainting, palpitations, chest pain, or serious heart failure. Atrial fibrillation leads to a higher risk of other diseases such as strokes due to the formation of blood clots from the blood that accumulates in the atrium because they are not fully transferred to the ventricle. In general, people with atrial fibrillation are seven times more likely to have a stroke than the general population, but other risk factors must also be considered.
Treatment for atrial fibrillation includes drugs to slow or regulate the heart rate, while a pacemaker can be installed to ensure that the electrical signal used to regulate contractions enables coordinated contractions. Surgery can be done to prevent the ear fiber from coming back. This can be minor (insertion of the catheter) or severe if the heart or power generation are severely damaged. People with atrial fibrillation are often treated with blood thinners such as warfarin to reduce the risk of blood clotting that causes a stroke.
Aging Information - Effects on Your Heart in Aging
It is inevitable, we are all getting older, there is no way out. However, there is no eternal staying forever; It is always a good idea to understand the effects of aging, especially on our hearts. Aging affects our hearts for a long time. Factors that change or accelerate aging and, if left untreated, can even lead to heart disease.
The first thing you need to understand is the basis of how the heart works. The heart consists of two sides. The right side pumps your blood into your lungs so it gets oxygen and then removes the carbon dioxide from your blood. While the left side of your heart pumps blood into your body that contains oxygen.
Arteries are what the blood needs to circulate, then branch, and become even smaller through the veins and tissues. Once they become small capillaries in the tissue of the body. In the capillaries and blood, oxygen and nutrients get into the tissue and absorb carbon dioxide and other wastes, which are returned to the heart.
Aging can change a lot. One would be our natural pacemaker that controls our heart rate. Sometimes aging can produce fibrous tissue and fat, which can lead to cell loss and slow heart rate. The left side of the heart may enlarge slightly, or the hearing wall may thicken with age. This changes the amount of blood the ventricle can hold and may fill up more slowly.
Age can also cause abnormal heart rhythms called arrhythmia or atrial fibrillation. However, this is a fast irregular heartbeat. These things can also be caused by heart disease rather than age. With age, the cells of the heart degenerate a little and the valves can become thicker and stiffer, which can slow down blood circulation. Heart murmurs can occur due to this stiffness.
There are receptors in the heart called baroreceptors that help monitor our blood pressure, and these sometimes change and become less sensitive to aging. Because of this, many older people's blood pressure drops quickly when they get up quickly, which often makes them dizzy.
The aorta generally becomes somewhat thicker, stiffer and less flexible with age. This has to do with the changes in the connective tissue of the blood vessels in the wall. This can cause higher blood pressure and make your heart much heavier.
Even your blood will change slightly with age. With age, it is normal for body water to decrease, which in turn means that there is less fluid in the actual bloodstream, so blood volume decreases. Red blood cells are also usually reduced, which is why the older you get, the easier it is to feel tired.
