What Happens When the Electrical Activity of Your Heart Changes?

The heart's electrical conduction system plays a very important role in cardiovascular functioning. Also known as the atrioventricular (AV) conduction system, it regulates and controls the timing of the heartbeat.

How does the heart's electrical conduction system work?

There is a collection of electrical cells in the upper right atrium of the heart known as the sinoatrial (SA) node which acts as a natural pacemaker and generates electrical signals. These signals travel through specialized electrical pathways and stimulate the muscular walls of the heart to contract in a rhythmic manner. This gives rise to the heartbeat that pulses at a specific frequency every minute.

What is the effect of fluctuations in electrical activity on the heart?

The standard heart rate in human being ranges from 60 to 100 beats per minute. It slows down when a person sleeps and speeds up when one experiences physical or emotional heightening. These fluctuations are triggered by the brain or other systems of the body and signal the SA node to generate charges more rapidly or slowly. This leads to spikes and drops in the heart rate, depending on the nature of the situation.

What happens when there is dysfunction in the heart's electrical activity?

When the heart's electrical conduction system does not function properly, it leads to the occurrence of a condition known as arrhythmia or abnormal heart rhythm. This happens when electrical impulses are generated in an irregular manner and causes tachycardia (rapid heartbeats) or bradycardia (slow heartbeats) which takes place in jarring infrequent tempos.

What causes fluctuations in the heart's electrical activity?

There are various kinds of triggers that cause the heart rate to fluctuate. The exact nature of fluctuation also depends on the type of trigger. A few everyday examples of these causes are as follows:
- Exercise and strenuous physical activity increases electrical activity as the heart is required to beat faster so as to increase the supply of blood and oxygen to the muscles.
- Sleep and rest reduce heart rate as the body is not needed to exert itself.
- Release of adrenaline into the bloodstream causes the heart rate to spike up.

Be it burgers, bagels, muffins, sandwiches or simple toasts, bread has made headway into the diets of a huge portion of the populace. Although a staple diet for many since time immemorial, the consumption of bread has increased extensively in the recent past. But, which type of bread should we intake to incur the best health impacts is a question that bothers many. The general assumption is that the wholegrain variety is the best alternative. However, the barrage of marketing tactics makes it impossible to distinguish the best variety from the others. 

There are a whole lot of myths surrounding the best variety of bread and you must choose wisely before settling for one particular type. It is expedient to look beyond the overt appearance or the name of the bread, one needs to be wary of the ingredient before taking a call.

Mostly, white bread is made out of refined flour which is often striped off essential nutrients and fibers. To worsen the situation, white bread is often bleached with certain chemicals to enhance its appearance.
Certain assumptions deem brown bread as the healthier option. Unfortunately, it isn't true always. More often than not, brown bread is simply white bread with artificial coloring added to it or is caramelized. They essentially add no surplus nutritional value.

Similarly, multigrain bread can often mislead the consumers about its health impacts. Unlike whole wheat bread, multigrain breads are usually chemically treated with softened grains. This does not effectively recover the lost nutrients of the bread.

Whole wheat bread has more pronounced health benefits. It contains more wheat germ and fibers in comparison to the more processed varieties of bread. Having evaded the toxic additives, it has relatively healthier effects on our blood sugar levels.

As you realize that the bread that you eat does not necessarily affect your health favorably, wisdom lies in seeking out the least harmful variety. In that context, rye bread or spelt bread contains greater amount of minerals. Besides, bread made from barley, oats and millets have greater mineral content than the commercially hybridized varieties and promote better health.

Brown Bread Vs White Bread Vs Whole Grain?

Arrhythmia is a disorder which is characterized by improper and irregular heartbeats; be it too slow or too fast. This problem occurs when the electrical impulses that are used to regulate your heartbeat don t work in the correct manner. Your heart may beat irregularly, too slow or too fast.

Symptoms
Although this disorder does not yield many symptoms, a few noticeable symptoms of arrhythmia are slow heartbeat, or a racing heartbeat, chest pain, breathing difficulties and dizziness. Arrhythmia can lead to inefficient pumping by the heart, leading to bouts of fainting. A severe symptom of this disorder is ventricular fibrillation, wherein the ventricles tend to quiver instead of transporting blood. This symptom can cut off blood supply to the vital organs, which may lead to death.

Causes

Coronary artery disease: In this disease, arteries of the heart can get blocked, leading to irregular heart beat and impaired heart functioning.
A heart attack: An ongoing heart attack usually leads to irregular heartbeats.
High blood pressure: High blood pressure problems make you more vulnerable to this condition.
Impaired functioning of the thyroid glands: An overactive or underactive thyroid gland can lead to heart arrhythmia.
Excessive smoking and alcohol consumption: These habits can cause problems with the blood vessels in the body, thus increasing risks of this particular condition as well as other cardio-vascular diseases.
Stress: Too much stress can lead to high blood pressure; that is again linked to heart arrhythmia.
Treatment
Mild symptoms of arrhythmia do not require treatment. However, complications resulting from it warrant treatment. The various treatment options for this condition are:

Pacemaker: A pacemaker is a device that is used to regulate your heart rhythms. It is placed in the body by a surgical procedure and an insulated wire is put, connecting the heart to the pacemaker. In case of an irregular heartbeat, the pacemaker sends out impulses to correct the improper heartbeat.
Implantable cardioverter-defibrillator: This device is used to prevent a dangerous symptom of heart arrhythmia, a symptom wherein the ventricle quivers. It is similar to a pacemaker as it is also placed near the collarbone. In case it detects an abnormal rhythm, it sends out shocks to reset the heart rhythm.
Maze procedure: This is a surgical procedure wherein incisions are made on the upper heart tissue to create a scar tissue. Scar tissues act as insulators to prevent stray impulses.
Alternative therapies: Alternative procedures such as yoga and meditation can help remedy the disorder.

Is Your Heart Missing a Beat Regularly - Could it be Arrhythmia?

Automatic Implantable Cardioverter Defibrillator is an electronic device that is located in the chest of the patient suffering from arrhythmia. Arrhythmia is a condition which causes abnormal rhythm of heartbeat in the patients. It is a life-threatening condition. The device is located in the chest to correct the rhythm of a heartbeat.

AICD device works in two ways:

Firstly, it tries to correct the abnormal heartbeat rhythm and release high- speed heartbeat pace. This is called cardioversion. Patients with AICD generally do not feel the process.

However, if the effect of cardioversion is null then the device will give a mild electric shock to the patient's heart to correct arrhythmia and reset the rhythm.

This second method is called defibrillation. The patient can feel the defibrillation.

The modern-day AICD device is programmed to store the data about the patient s heart rhythm. Doctors use the programmed device which contains your condition and provides medically correct therapy.

Preparation for AICD Implantation

The patient is required to fast six hours before undergoing the surgery. On admission, prescribed medicine is given to the patient and the latest heart condition is measured by an ECG test. If the patient is on blood-thinning medication, then it will be stopped 24 hours before the surgery.

The procedure will be carried out by a cardiologist. The patient will remain under observation in the hospital for at least two days.

Procedure

The entire process of setting up the device in the chest of the patient takes about 2 hours. The patient is sedated, and the area below the collarbone is numbed for the operation. A small incision is made in the chest area. With the help of imaging techniques, cardiologist sets up the device in the chest. The device is then connected to the veins and the heart. After the surgery, the patient is kept under observation. Heart rate, blood pressure, and overall health condition are observed by the doctors to determine successful implantation of Automatic Implantable Cardioverter Defibrillator (AICD). Post Procedure After the successful recovery of the patient, doctors usually discharge the patient with AICD attached. The doctors give complete care instructions of the device along with health. Doctors also guide the patient through the list of activities that one can and cannot perform. AICD is a life-saving device. Hence, proper care and regular check-ups are recommended by the doctors. The regular check-up of the device is also essential since the device runs on a battery. The doctors also train the patient about the workings of the device. They will also explain about the mild shocks of the device one may receive to correct the arrhythmia. Before leaving, make sure the site of the surgery is dry and healing, and you do not have a fever for the past 24 hours.

AICD Implantation - Know Procedure Of It!

On an average a person consumes nearly 800 calories daily from added sugar.
