What Causes an Arrhythmia? What Causes an Arrhythmia? An arrhythmia can occur if the electrical signals that control the heartbeat are delayed or blocked. This can happen if the special nerve cells that produce electrical signals don't work properly. It also can happen if the electrical signals don't travel normally through the heart.

Overview But some types of arrhythmia can be serious and lead to a sudden stop in heart function (sudden cardiac arrest). The most common cause of cardiac arrest is an arrhythmia called ventricular fibrillation — when rapid, erratic electrical impulses cause your ventricles to quiver uselessly instead of pumping blood.

Heart Diseases & Disorders Disease Categories. Electrical: Abnormal heart rhythms (arrhythmias) are caused by problems with the electrical system that regulates the steady heartbeat. The heart rate may be too slow or too fast; it may stay steady or become chaotic (irregular and disorganized).

Heart Attack An arrhythmia is a deviation from the heart's normal beating pattern caused when the heart muscle is deprived of oxygen and is a dangerous side effect of a heart attack. A very fast or slow rhythmic heart rate often occurs in patients who have had a heart attack, and is not usually a dangerous sign.

Arrhythmia: Causes, symptoms, types, and treatment An arrhythmia describes an irregular heartbeat - the heart may beat too fast (tachycardia), too slowly (bradycardia), too early (premature contraction), or irregularly (fibrillation). Arrhythmias occur when the electrical signals to the heart that coordinate heartbeats are not working properly. Many heart arrhythmias are harmless.

What Causes an Arrhythmia? What Causes an Arrhythmia? An arrhythmia can occur if the electrical signals that control the heartbeat are delayed or blocked. This can happen if the special nerve cells that produce electrical signals don't work properly. An arrhythmia also can occur if another part of the heart starts to produce electrical signals.

Arrhythmias Overview. A problem with any part of the heart's electrical system can cause an arrhythmia. Most arrhythmias are harmless, but some can be serious. ICDs use electrical pulses or shocks to treat life-threatening arrhythmias that occur in the ventricles (the heart's lower chambers). When ventricular arrhythmias occur, the heart can't pump blood well. You can pass out within seconds and die within minutes if not treated.

Heart arrhythmia Sudden cardiac death is the cause of about half of deaths due to cardiovascular disease or about 15% of all deaths globally. About 80% of sudden cardiac death is the result of ventricular arrhythmias. Arrhythmias may occur at any age but are more common among older people.

Overview Heart arrhythmia. Overview. Heart rhythm problems (heart arrhythmias) occur when the electrical impulses that coordinate your heartbeats don't work properly, causing your heart to beat too fast, too slow or irregularly. Heart arrhythmias (uh-RITH-me-uhs) may feel like a fluttering or racing heart and may be harmless.

- In subrogation litigation, the first thing that the lawyer handling the case wants to do is figure out whether the defendant has any money. If the lawyer determines that the defendant has absolutely no money, no assets, and little chance of ever getting any money or assets, the lawyer may very well drop the case.

I or the Doctor Can Feel the Babyâs Head When Checking my Cervix Being familiar with your cervix can also help you understand effacement; that is when the cervix prepares itself for the birth of your baby. Once engaged (at around 36 weeks), your baby will drop closer to the cervix. At this stage of the pregnancy your cervix will be softer and thinner the closer to your due date.

Electrolytes & Cardiac Arrhythmias According to the American Heart Association, potassium imbalances are the most common electrolyte-associated cardiac arrhythmias. Potassium plays a role in both nerve conduction and the heart’s ability to send an electrical impulse. Low potassium levels can cause relatively stable arrhythmias, while high potassium levels can quickly lead to lethal arrhythmias. Sodium, magnesium and calcium imbalances also place the heart at risk for arrhythmias.

- Atrial fibrillation is a very common irregular heart rhythm that causes the atria, the upper chambers of the heart, to contract abnormally. Atrial flutter. This is an arrhythmia caused by one or more rapid circuits in the atrium. Atrial flutter is usually more organized and regular than atrial fibrillation.

Why Arrhythmia Matters The most common cause of stroke from an arrhythmia is atrial fibrillation. Atrial fibrillation can cause blood clots to form in the atria (top chamber of the heart) where they can be pumped out of the heart, to the brain, blocking a blood vessel and causing a stroke.

- Atrial fibrillation -- the most common type of cardiac arrhythmia -- causes an irregular heartbeat that can increase your risk for stroke and heart failure. Atrial fibrillation (AF or AFib) results from faulty signals produced by the heart's electrical system, causing the upper portion of the heart to fibrillate, or contract rapidly and irregularly.
