However, sometimes it's normal for a person to have a fast or slow heart rate. For example, the heart rate may increase with exercise or slow down during sleep. Heart arrhythmia treatment may include medications, catheter procedures, implanted devices or surgery to control or eliminate fast, slow or irregular heartbeats. A heart-healthy lifestyle can help prevent heart damage that can trigger certain heart arrhythmias.

Although a heart rate below 60 beats a minute while at rest is considered bradycardia, a low resting heart rate doesn't always signal a problem. If you're physically fit, your heart may still be able to pump enough blood to the body with fewer than 60 beats a minute at rest.

If you have a slow heart rate and your heart isn't pumping enough blood, you may have a type of bradycardia. Types of bradycardias include:. Premature heartbeats are extra beats that occur one at a time, sometimes in patterns that alternate with the normal heart beat.

The extra beats may come from the top chamber of the heart premature atrial contractions or the bottom chamber premature ventricular contractions. A premature heartbeat may feel like your heart skipped a beat.

These extra beats are generally not concerning, and they seldom mean you have a more serious condition. Still, a premature beat can trigger a longer-lasting arrhythmia, especially in people with heart disease. Occasionally, very frequent premature beats that last for several years may lead to a weak heart. Premature heartbeats may occur when resting. Sometimes premature heartbeats are caused by stress, strenuous exercise or stimulants, such as caffeine or nicotine.

Heart arrhythmias may not cause any signs or symptoms. A doctor may notice the irregular heartbeat when examining you for another health reason. If you feel like your heart is beating too fast or too slowly, or it's skipping a beat, make an appointment to see a doctor. Seek immediate medical help if you have shortness of breath, weakness, dizziness, lightheadedness, fainting or near fainting, and chest pain or discomfort.

A type of arrhythmia called ventricular fibrillation can cause a dramatic drop in blood pressure. Collapse can occur within seconds and soon the person's breathing and pulse will stop. If this occurs, follow these steps:.

To understand the cause of heart arrhythmias, it may be helpful to know how the heart typically works. This rhythm needs a shock to stop it and return the heart back to a normal rhythm.

A cardiac arrest can soon follow if the rhythm is not treated quickly with a shock. Ventricular Tachycardia - A fast rhythm which causes the heart to pump less efficiently, and can lead to dizziness, fainting and unconsciousness. Definitions and abbreviations Definitions of the frequently used words and abbreviations related to cardiac arrhythmias.

Arrhythmia - Irregular heart rhythm Atria - Top chamber of the heart Atrium - Top chambers of the heart that receive blood from the body and the lungs. The blood supply to part of the heart muscle is blocked, causing part of the heart muscle to die Heart block - Electrical impulses are slowed or blocked as they travel from the top to the bottom chambers of the heart Heart Failure - When the heart fails to pump blood to the body's organ systems and keeps organs working efficiently Implantable Loop Recorder - Monitor implanted for a period of time to record your rhythm ICD - Implantable Cardioverter Defibrillator Pacemaker - A small, sealed electrical device which is connected to you heart.

A pacemaker can monitor your heart and produce electrical impulses to treat abnormal heart rhythms PVI - Pulmonary Vein Isolation Pulse generator - Part of the ICD which contains a battery and electric circuits Sinoatrial node - the heart's natural pacemaker Supraventricular Tachycardia SVT - A rapid abnormal heart rhythm that begins in the upper chambers of the heart.

Syncope - Loss of consciousness due to Bradycardia or asystole Ventricles - The two lower chambers of the heart. Electroencephalography, when wires are placed on the head to read the electrical output of the brain. Occurs when one of the coronary arteries becomes blocked by a blood clot. The blood supply to part of the heart muscle is blocked, causing part of the heart muscle to die. Also known as myocardial infarction.

When electrical impulses are slowed or blocked as they travel from the top to the bottom chambers of the heart. Left atrial appendage. A small pouch on the heart where clots can form. A procedure can close off occlude the pouch and thereby prevent clots from travelling to the brain and causing an AF-stroke. Oral anticoagulants sometimes known as blood thinners which may be divided into vitamin K antagonists e.

A small, sealed electrical device which is connected to you heart. A pacemaker can monitor your heart and produce electrical impulses to treat abnormal heart rhythms. Also known as a 'brain attack'. Has differing levels of severity and recovery.

Can be caused by a clot blocking an artery ischaemic stroke or a bleed haemorrhagic stroke. Supraventricular Tachycardia - A rapid abnormal heart rhythm that begins in the upper chambers of the heart.

The two lower chambers of the heart. The right ventricle pumps blood into the lungs and the left ventricle pumps blood around the body.
