People who suffer from the frequent breathing interruptions of sleep apnea have a two to four times increased risk of cardiac arrhythmias as they slumber, a new U.S. study finds.", "An old heart attack leaves behind a scar.

Electrical short circuits around the scar can prevent normal heart function by causing the heart to beat dangerously fast (ventricular tachycardia) or to quiver (ventricular fibrillation).", "The Dangers of an Unhealthy Heart:

When heart tissue becomes damaged or dies, it can affect the way electrical impulses spread in the heart. Source: nih.gov", "Bradycardia is excessive slowness in the action of the heart, usually with a heart rate below 60 beats per minute.", "Atrial fibrillation is the most common sustained heart rhythm disorder and increases the risk for heart disease and stroke.

Both of these conditions are leading causes of death in the United States.

An estimated 2.2 million adults in the United States have been diagnosed with atrial fibrillation.", "Atrial fibrillation is the quivering of the top right chamber of the heart.

It is characterized by a rapid and irregular beat that can cause serious complications, even death.

If the heart rate is rapid and irregular, a healthcare provider should be seen quickly.An ideal adult pulse is steady with regular rates of 60-80 beats per minute. Source: CDC", "Persons can identify an irregular heartbeat by monitoring their wrist pulse for 1 minute.

The irregularity of these beats is detected and the next beat cannot be predicted.

People who identify the signs of cardiac arrhythmia should seek medical care to determine the presence of atrial fibrillation or other heart disorders.", "A Temper Can Be Dangerous:

The adrenaline released in outbursts of anger may place individuals with a history of irregular heartbeat at heightened risk for cardiac arrest, a recent study suggests.", "Researchers have identified a gene that plays an important role in making sure the heart beats properly.

This discovery that could cast light on the abnormal heartbeats called arrhythmias that often lead to major cardiac problems.", "By taking omega-3 fatty acids...

patients can reduce their risk for dangerous arrhythmia after bypass surgery by more than 50 percent, a recent study suggests.", "Research has shown that stem cell therapy can regrow damaged cardiac tissue in patients after a heart attack.

However, that same research found the cutting-edge procedure also raised the risk for dangerous heart arrhythmias.", "Fish oil may help counter air pollution-linked changes in heart function, a new study suggests.", "Overweight and obese people are at especially high risk of developing a potentially fatal abnormal heart rhythm after heart surgery, a recent study finds.

The study of more than 8,000 cardiac surgery patients is the first to identify a strong, independent association between excess weight and the development of this arrhythmia, called post-operative atrial fibrillation.", "Generating intense radio waves to kill tiny areas of flawed heart tissue can bring permanent relief to people who have suffered for years from atrial fibrillation, a new study finds.

Atrial Fibrillation is the most common form of abnormal heart rhythm.", "A wild roller coaster ride can trigger an irregular heartbeat in some riders.

This could lead to death among those with cardiac conditions.", "Fish oil -- either from a diet rich in fish or from supplements -- is generally considered heart-healthy.

But a new study found that for some people, fish oil supplements may have no effect or may even be dangerous. ", "Risks of Fish Oil?

In people who have an implantable cardiac defibrillator because they have a history of irregular heartbeats, fish oil supplements may increase their risk of life-threatening heart rhythm abnormalities.", "Heart Attack During Exercise Rare in Women:

A new study has found that sudden cardiac death during exertion is extremely uncommon in women, and perhaps even more uncommon in women who exercise regularly.", "Stomach Bacteria Linked To Irregular Heartbeats:

Helicobacter pylori, a bacteria that lives in the stomach and small intestine and causes ulcers, may also be linked to a dangerous, irregular heart rhythm known as atrial fibrillation (AF), a recent study suggests.", "Pollution exposure...

can affect heart rate variability, a measure of the autonomic nervous system's regulation of the heart. Heart rate variability is an independent risk factor for cardiac arrhythmias, heart attack and sudden death.", "Implantable defibrillators save lives, but...

that shock can also cause physical and psychological trauma for the patient.

However, a new Canadian study shows that drugs that help prevent abnormal heartbeats can reduce the need for defibrillator shocks,", "As many as 2.2 million Americans are living with atrial fibrillation (one type of rhythm problem).

Arrhythmias can occur in a healthy heart and be of minimal consequence. They also may indicate a serious problem and lead to heart disease, stroke or sudden cardiac death.", "The Dangers of Rapid Heart Rhythms:

Rapid heart rhythms account for the great majority of sudden cardiac deaths.", "During a 24-hour period...

about one-fifth of healthy adults are likely to have frequent or multiple types of premature ventricular heartbeats.", "Ventricular fibrillation is a...

condition in which disordered electrical activity causes the ventricles to contract in a rapid, unsynchronized, uncoordinated fashion.

When this occurs, little or no blood is pumped from the heart.

Collapse and sudden death follows unless medical help is provided immediately. If treated in time, ventricular tachycardia and ventricular fibrillation can be converted into normal rhythm with electrical shock.", "Under some conditions almost all heart tissue can start a heartbeat.

Cells in the heart's conduction system can fire automatically and start electrical activity.

Normally, the heart's most rapidly firing cells are in the sinus node, making that area a natural pacemaker.", "Have you ever felt your heart 'skip a beat?'

In these cases, the heart doesn't really skip a beat. Instead an extra beat comes sooner than normal. Then there's a pause that causes the next beat to be more forceful. You felt this more-forceful beat."];
