What is normal heart rate?

When the heart beats, an electrical impulse causes the heart to contract through a specific pathway. Any interruption in impulse can lead to arrhythmias.

The heart is divided into four rooms. Space on each half of the heart form a kind of two pumps side by side, which consists of an upper chamber (atrium) and lower chamber (ventricle).

When the heart beats, the atria contract and fill the ventricles with blood. Contraction is initiated when the sinus node, a small group of cells in the right atrium, sends electrical impulses that cause the right atrium and left to contract.

The impulse then travels to the heart center, to the atrioventricular which lies in the path between the atria and ventricles.

From here, impulses out of the atrioventricular and propagate through the ventricles, which makes the heart contracts to pump blood throughout the body. In a healthy heart, this process usually goes smoothly, producing a normal heart rate from 60 to 100 beats per minute. In general, when resting, the athlete has a heart rate of less than 60 beats per minute because their hearts are so efficient.

arrhythmia is an abnormal heart rhythm that is a sequence of irregular heart beats, too fast, too slow, or do melalaui abnormal electrical pathways in heart. Cardiovascular disorders are the most common cause of abnormal heart rhythms (arrhythmias).

Sometimes people are aware of abnormal heart rhythms, tetapai consequently most of them just feel like a lethargic or unconscious. Diagnosis is based on electrocardiography. Treatment involves the recovery of cardiac arrhythmia to a normal rhythm and prevent further episodes.

What causes arrhythmia

TThe most common cause of arrhythmias is heart disease, particularly coronary artery disease, heart valve disorders, and heart failure. Many prescription or OTC drugs including those used to treat heart disorders, can cause arrhythmias. Some arrhythmias are caused by anatomic abnormalities are present from birth (congenital birth defects). Age-related changes in the electrical system causing cardiac arrhythmias occur more easily. An overactive thyroid gland (hyperthyroidism), produce high levels of thyroid hormone, can cause rapid arrhythmias. The thyroid gland is underactive (hypothyroidism), resulting in low thyroid hormone can cause slow arrhythmias. Sometimes there is no identifiable cause of arrhythmia.

Tachycardia can be caused by exercise, emotional stress, excessive alcohol consumption, smoking, or using drugs emngandung stimulant, such as flu and fever medicine. Arrhythmias slow (bradycardia) can be caused oelh pain, hungry, tired, digestive disorders (such as diarrhea and vomiting), or bloating, stimulates the vagus nerve yangd apat redundant (with sufficient stimulation, although rare, the vagus nerve can cause the heart to stop) in the most circumstances, arrhythmias can be done by itself.

Symptoms of arrhythmia

Some people with arrhythmias may be noticed. But awareness of the heartbeat (palpitations) varies between each person. Some people can feel the heartbeat is normal, and most people can feel heartbeats when they lie on their left side.

Arrhythmias have the consequences that range from harmless to life threatening. Seriousness of the arrhythmia may not be closely related to the severity of the symptoms it causes. Some arrhythmias are life-threatening no symptoms, and some are not life-threatening arrhythmias can cause severe symptoms. Often, the nature and severity of underlying heart disorder is more important than the arrhythmia itself.

 When arrhythmias impair the ability of the heart to pump blood, they can cause weakness, reduced ability to exercise, shortness of breath, dizziness, dizziness and ingsan. Fainting occurs when the heart pumps inefficiently so they no longer maintain adequate blood pressure. If the deaths continue to occur. Arrhythmias can also exacerbate underlying heart disorder symptoms, including chest pain and shortness of breath. Arrhythmias that cause symptoms require immediate attention.

Treatment for arrhythmia

For patients who develop arrhythmias are harmless, to ensure that the treatment is harmless enough. Sometimes the occurrence of arrhythmia is reduced or even stopped when the patient’s doctor to change medications or reset the dose. Avoiding alcohol, caffeine (in food and beverages), or smoking may also help. Avoid hard exercise can help if flutter occurs only during exercise.

 World Health Organization (WHO) estimates that a quarter to half of adults have periodontitis. While obesity known to be associated with systemic inflammation. But weight loss can protect your teeth?

A review of 2011 reported in the journal Obesity Review analyzed a total of 33 studies to examine the relationship between obesity and periodontitis. Known as much as 30 studies found an association between body composition and periodontitis.

A person who is known to have body fat levels are higher, then it is more likely to have periodontitis even in more severe cases or losing his teeth, as quoted from MSNHealth, Thursday (08/12/2011).

A variety of different studies that collected is known as a whole if a person is overweight or obese then it has a chance 2 times suffering from periodontitis.

This is because fat people who lose weight show a reduction in all measured inflammation, and possibly also reduce the risk of dental disorders such as periodontitis.

Besides having a healthy weight also can keep a person from a variety of risks such as heart disease, stroke, diabetes and cancer, as long as the method of doing right and not extreme.

During this time, the world of health have not been able to find a drug to treat Alzheimer’s disease. There is only giving some kind of medication to prevent symptoms of dementia to getting worse.

But a group of researchers from Sweden’s Lund University found the development of treatments for Alzheimer’s patients. From the results of their research revealed, high vitamin C was able to heal damaged cells in patients with Alzheimer’s.

Vitamin C can restore protein in brain cells are damaged. When the protein was recovered, the nerve cells that regulate a person’s memories will recover.

Until now, scientists still continue to develop their research and will display the results in medical journals world.

This new study conducted by researchers in collaboration with the University of Wisconsin-Madison (UWM) School of Medicine. The team drew inspiration from the observation that the surface of cells and biologically active molecules contained in the sugars have a basis in a structure.

Interestingly, the sugar is not used to store energy (commonly used in the body), but is used to regulate processes such as immunity, infection and inflammation. This makes scientists think that such molecules may also be useful for the treatment to the patient.

UMW professor of pharmaceutical sciences, Jon Thorson understand how the process of sugar to attach and function in the human body. He also believes that this is a major breakthrough.

“The content of chemicals on sugar is hard to understand, so we have been doing research with a method for making sugar more familiar with the user,” said Thorson.

Together with colleagues from the UMW, Richard Gantt and Pauline Peltier, they developed a method to remove sugar molecules from the carrier molecule. Then the sugar molecules are added to existing drugs, or various other chemicals.

Interestingly, a molecule that is able to accept the color change of sugar, give feedback mechanism that allows researchers to know if the procedure has been completed successfully.

“One molecule can be placed on 1,000 types of drugs on the plate and the different colors will show up after receiving additional sugar. These findings are very important for scientists in developing new drugs against various diseases,” said Thorson.

“We have a new more selective approach in the treatment of cancer,” said John Bell, a senior scientist at the Ottawa Hospital Research Institute in Canada. This treatment is helpful in the treatment of metastatic cancer or cancer that has spread throughout the body.

This small study done in Canada and involved only 23 patients as the initial clinical trial. The researchers used a weak-type vaccine virus used in smallpox. When inside the tumor cell, virus which called JX-594, take over the function of cells to replicate themselves. The virus is a parasite on the tumor cell and kill it.

“Coarse comedy (slapstick) giving the higher effect of pain reduction than with other types of comedy,” said Dunbar.

It is natural that women who entering the 20-30 age began to show changes in their skin. Even many women who have experienced premature aging. Direct sunlight, stress and environmental pollution becomes an important factor in skin aging. Factors such as smoking, alcohol or unhealthy diet also affects the skin damage. Here are the signs of premature aging of the skin that you should beware.

1. Wrinkles. One of the easiest signs of premature aging is wrinkles. American Academy of Dermatology explains, these wrinkles appear due to the sun, and getting worse if you smoke. These two factors will damage to the DNA skin cell membranes. Collagen and elastin, proteins that are useful for skin health and beauty. Hereditary factors, such as genetics and race, in fact also affects how quickly one becomes wrinkled.
2. Blackish stains including signs of premature aging commonly called age spots, will appear with a darker color than surrounding skin. According to the National Institutes of Health, age spots commonly found in humans that has been aged above 40 years who spend much of their time in the sun. It usually appears in the arms, hands, face, forehead and shoulders (just the parts that are easily exposed to direct sunlight).
3. Rough skin texture. Collagen and elastin will be damaged if it constantly gets sun. Collagen is useful to maintain strength and elasticity of the skin, while elastin will make the skin firm and flexible. Too many are under the sunlight will make the skin look dry and coarse.
4. Dilated pores. This is also attributed as signs of premature aging of the skin. The more a person gets older, the pores will be even greater due to the cumulation of dead skin. Enlarged pores can be overcome by diligent skin care that includes removal of dead skin cells.

So when you have seen signs of premature aging you should immediately consult a doctor or do skin care treatment. Hopefully article Signs of Premature Aging can provide benefits to you. Let’s keep health by eating healthy foods.

Eating apples and pears can reduce the risk of stroke. That is what has been published in the Stroke journal on the BBC. However, researchers from Netherlands still do not know why people who consume apples, pears even pineapple and cabbage in high amounts can lower the risk of stroke by 25%.  At the beginning of the study, respondents from the Netherlands asked to fill out questions about diet and lifestyle in previous years. By using information and health records of respondents more than 10 years later, researchers examined the relationship between vegetables and fruits with risk of stroke.

Researchers found that consuming 25 grams of vegetables and fruit per day can lower white 9% risk of stroke. More than half of respondents claimed to consume apples and pears. So far, they have not found a relationship between stroke and colored vegetables or fruit.

Linda Oude Griep, from the University Wagenginen, Netherlands, said, need further research why white vegetables and fruits are very useful to fight against stroke.

Researchers from the China Medical University in Taichung, Taiwan, Iching Cou, say, this possibility is a factor of pathogenesis or the transmission of the same disease. The study was conducted by monitoring the health of 5195 schizophrenics and 11,527 people with epilepsy in Taiwan between 1999-2008.

The data compared with those patients who do not suffer from schizophrenia or epilepsy in the same group and age.
