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.

4) Practice saying Thank You - It's very simple. When you buy a bus ticket, just smile and say 'Thank You. Feel the first raindrops on your face and smile in gratitude for all the life it brings.

5) Focus your attention outwards - According to Emmons, a US psychology professor, people who are more aware of the positives in their lives tend to focus their attention outside of themselves.

5 Reasons Why Some People Accomplish More And Are Much Happier

Hiatal hernia takes place when the upper portion of the stomach pushes itself through an opening in the diaphragm, into the chest cavity. The diaphragm is a wall of thin muscles, which separates the chest cavity and the abdomen. In most cases, a small hiatal hernia doesn't cause problems and you may never know you have a hiatal hernia unless your doctor discovers it when checking for another condition.

But a large hiatal hernia can allow food and acid to back up into your oesophagus, leading to heartburn. Self-care measures or medications can usually relieve these symptoms, although a very large hiatal hernia sometimes requires surgery.

Causes

Hiatal hernia is primarily or most commonly caused due to the increase in pressure in the abdominal cavity. Sometimes, a lot of pressure may be felt around the stomach accompanied by coughing, vomiting, strain during bowel movements. For people born with an abnormal hiatus, the chance of getting hiatal hernia is more.

The two common types of hiatal hernia are:

 Sliding hiatal hernia, which occurs during the sliding out of the stomach and oesophagus into and out of the chest through the hiatus. This type of hiatal hernia is less intense and has no symptoms.
 Fixed hiatal hernia or paraoesophageal hernia is an uncommon type of hernia where a part of the stomach pushes through the diaphragm and stays there.

Symptoms

Usually, no symptoms are experienced during hiatal hernia. Some symptoms are experienced that happen due to stomach acids, bile or air, which enters the oesophagus. Some common symptoms include:

 Heartburns which become worse when a person lies down
 Chest pain, better called epigastric pain
 Problem in swallowing food
 Belching

Tests for diagnosis

Several tests can be carried out for the diagnosis of hiatal hernia. They include:

 Barium x-ray, where a person is made to drink a liquid filled with barium before the x-ray. The x-ray provides a clear image of the upper digestive tract region and the location of the stomach can be seen. If it is protruded out, hiatal hernia is signified.
 Endoscopy is another test for detection of hiatal hernia. A thin tube slides down the throat, which reaches up to the oesophagus and stomach. This will determine whether the stomach is pushing through the diaphragm or not.

Treatment

Medicines, which are used to cure a hiatal hernia may include antacids for neutralizing stomach acid, h2 receptor blockers to lower acid production and proton pump inhibitors. Sometimes fundoplication surgery is required for the treatment of hiatal hernia, although it is rare. Some common surgical techniques are rebuilding of oesophageal muscles or a surgery to put the stomach back in its actual place. Laparoscopic surgery methods are used. Hiatal hernia may reoccur even after surgery; so general precautions should be taken. You should:

 Exercise regularly and maintain a healthy weight
 Avoid lifting heavy objects and ask for help
 Avoid any kind of strain on the abdominal muscles

Hiatal hernia is a disorder, which is more common among people over the age of fifty. Necessary precautions and treatment should be adopted in case of hiatal hernia.


All About Hiatal Hernia

An autoimmune disease often develops when your immune system, which guards your body against any kind of illness, starts attacking your own body. It decides that your healthy cells are foreign and attacks the healthy cells. Depending upon the type of illness, an autoimmune disease can influence one or various types of body tissue. It can bring about unusual organ development and changes in organ functioning.


A good diet is essential and a basic requirement so that it does not trigger aggravation in the digestion systems and further weaken your intestines. The diet should be taken in small portions to avoid bloating in the stomach. One should eat in small portions after every two to three hours. Some of the dietary measures for an autoimmune disease are as follows-


Stay away from gluten: In case you have an autoimmune disease, you generally require a lab test to know that you need to stay away from gluten. This protein, which is found in wheat, spelt, rye and grain, is connected to numerous immune system conditions.
Locate your reactive foods and discontinue them: Even grains that do not contain gluten like corn and rice can cause reactions in the immune system in a few people. Atomic mimicry happens when your body confuses your own body tissue for the similar kind of proteins found in a few foods. See whether you are having any food that you might be allergic to.
Include green tea and turmeric into your daily diet: They dampen the autoimmune reaction in many parts of the body especially the brain.
Stay away from refined table salt: Table salt has been shown to irritate and aggravate some of the autoimmune conditions.
Consume egg whites: They have anti-bacterial components and have the property to bind some of the nutrients. A few people will argue that they're fine when cooked. However, if you choose to just have the yolks, you can do so without any worry.
Take a healthy meat diet: Some meats like chicken, fish, sheep and turkey are good for the health. Swordfish and lord mackerel are high in mercury. Select infection free chicken, turkey, and sheep.
Consume low Glycemic Organic Fruits: Consume fruits including apples, apricots, avocados, berries, cherries, grapefruit, lemons, oranges, peaches, pears, plums for healthy glucose absorption.
Coconut intake: Coconut margarine, coconut cream, coconut milk, coconut oil, unsweetened coconut pieces, unsweetened coconut yogurt are great for health.
Herbs and Spices: Spices like basil, dark pepper, cilantro, coriander, cumin, garlic, ginger, lemongrass, mint, oregano, parsley, rosemary, sage, ocean salt and thyme should be used.
Fermented food: Kimchi, cured ginger, aged cucumbers, coconut yogurt, kombucha, water kefir, and so forth need to be consumed for the vitamins and nutrients they contain.

3. Transvaginal ultrasound: A transvaginal ultrasound uses high-intensity sound waves so that pictures of the uterus can be taken.
4. Biopsy: During a biopsy, the doctor will remove tissue from the endometrium and it will then be analyzed for cancerous growths.

Treatment

1. Surgery: This is the most common treatment as it removes the entire uterus and prevents the spreading of the cancer.
2. Chemotherapy: Chemotherapy involves giving drugs which kill cancerous cells. They are given through either an intravenous line or even in pill form.
3. Hormone therapy: This is a therapy in which either progesterone levels are increased or estrogen levels are decreased.
4. Radiation therapy: In this treatment, high energy laser beams are used to destroy cancerous cells.
