	Arrhythmia
		The arrhythmia can be manifested as rapid and regular heart beats (tachycardia), rapid and irregular heartbeats (fibrillation), slow heart beats (bradycardia), and abnormal extra beats occurring before the anticipated normal beats in a periodic fashion (premature contractions).
		Arrhythmias originating from the upper chambers (above the ventricles) of the heart are called supraventricular arrhythmias.
		Because of the sporadic nature of the arrhythmias, the better option is to attach the electrodes to the patient's chest which are then connected to a tape recorder.

	Arrhythmia - Texas Heart Institute Heart Information Center
		Arrhythmias can be divided into two categories: ventricular and supraventricular.
		Supraventricular arrhythmias happen in the structures above the ventricles, mainly the atria, which are the heart's two upper chambers.
		Arrhythmias are further defined by the speed of the heartbeats.

	Arrhythmia: A Problem With Your Heartbeat -- familydoctor.org
		Minor arrhythmias may be caused by excessive alcohol use, smoking, caffeine, stress or exercise.
		In general, arrhythmias that start in the lower chambers of the heart (called the ventricles) are more serious than those that start in the upper chambers (called the atria).
		When an arrhythmia is caused by a certain area of the heart, sometimes that part of the heart can be destroyed or removed.

	Arrhythmia - My Child Has - Children's Hospital Boston
		An atrial arrhythmia is an arrhythmia caused by abnormal function of the sinus node, or by the development of another atrial pacemaker within the heart tissue that takes over the function of the sinus node.
		A ventricular arrhythmia is an arrhythmia caused by abnormal function of the sinus node, an interruption in the electrical conduction pathways or the development of another area within the heart tissue that takes over the function of the sinus node.
		Arrhythmias may be short-lived in nature and not seen during the shorter recording times of the resting EKG.

	Arrhythmia - abnormal rapid heartbeat, tachycardia, bradycardia - Patient Health International
		Arrhythmias occur for different reasons but usually indicate that there are changes, possibly diseases, in the heart, of which some are more serious than others.
		Arrhythmias usually happen when the heart is injured or damaged, for example, in heart valve disease, heart failure, heart muscle disease, during attacks of angina or after a heart attack.
		Arrhythmias are caused by abnormal electrical signals within the heart being produced by injury that disrupts the normal pattern; for example, in the upper chambers, this could result in atrial fibrillation or tachycardia.

	Arrhythmia Treatments - Texas Children's Heart Center
		An arrhythmia is a condition in which the heart’s electrical conduction system is disrupted.
		Arrhythmias usually are not dangerous unless they cause a severe decrease in the heart’s pumping function.
		Arrhythmias often are treated with medication — to slow or speed the heart rate — and radiofrequency catheter ablation.

	WSAVA 2001 - Canine Cardiomyopathy
		Myocardial diseases are a common cause of heart failure, arrhythmia, and cardiovascular mortality in the dog.
		ACM must be distinguished from other causes of cardiac arrhythmia such as an atrial tumor (hemangiosarcoma), electrolyte imbalance (hypokalemia), splenic tumor, or post-operative ventricular arrhythmia (probably caused by ischemia and reperfusion).
		Similarly, a medication history should be obtained to insure the arrhythmia is not caused, for example, by ongoing treatment for respiratory disease (using sympathomimetic airway dilators) or by therapy for hypothyroidism (excessive supplementation resulting in iatrogenic hyperthyroidism).

		An arrhythmia is an abnormality in the heart's rhythm, or heartbeat pattern.
		Arrhythmias are deviations from the normal cadence of the heartbeat, which cause the heart to pump improperly.
		Arrhythmias occur when the heartbeat starts in a part of the heart other than the sinus node, an abnormal rate or rhythm develops in the sinus node, or a heart conduction "block" prevents the electrical signal from traveling down the normal pathway.

	Arrhythmia
		Arrhythmias are erratic heartbeats caused by irregular electrical impulses that regulate the heart’s rate and rhythm.
		Arrhythmias may occur in the atria or the ventricles.
		Arrhythmia is often associated with other forms of heart disease and is a leading contributor to stroke, congestive heart failure and sudden cardiac arrest.

	Abnormal Heart Rhythm, Arrhythmia, Heart Pacemaker
		Arrhythmias may have many causes, including: coronary artery disease, high blood pressure, changes in the heart muscle (cardiomyopathy), valve disorders, electrolyte imbalances in the blood (such as sodium or potassium), injury from a heart attack, the healing process after heart surgery and some other medical conditions.
		Arrhythmias that are recurrent or related to an underlying heart condition are more concerning and should always be evaluated by a doctor.
		Arrhythmia surgery also may be recommended if you need surgery to correct other forms of heart disease (such as valve or bypass surgery).

	Kellogg’s Smart Start Healthy Heart: Arrhythmia
		Cardiac arrhythmia refers to irregular heart action caused by disturbances in the discharge or transmission of electrical impulses.
		Some arrhythmias are so brief (for example, a temporary pause or premature beat) that the overall heart rate or rhythm isn’t greatly affected.
		But if arrhythmias last for some time, they may cause the heart rate to be too slow or too fast or the heart rhythm to become erratic.

	Heart Disease and Abnormal Heart Rhythm
		arrhythmias can occur with a normal heart rate, or with heart rates that are slow (called bradyarrhythmias -- less than 60 beats per minute).

	Facts on arrhythmia
		Arrhythmias are identified by where they occur in the heart (atria or ventricles) and by what happens to the heart's rhythm when they occur.
		Arrhythmias arising in the atria are called atrial or supraventricular (above the ventricles) arrhythmias.
		An arrhythmia may not occur at the time of the exam even though symptoms are present at other times.

	Arrhythmia
		Although the occurrence of an arrhythmia does not necessarily indicate an underlying heart condition (Read about "The Heart and Cardiovascular System"), AAFP says you should see a doctor if you experience an arrhythmia often, or if you have symptoms such as a rapid heartbeat (called "tachycardia"), shortness of breath, or dizziness.
		An arrhythmia is identified on the basis of where it occurs.
		If an arrhythmia is present, and it appears to be caused by heart disease, it's important to identify the underlying causes of the heart disease.

		The arrhythmia originates in the tissues near the AV node, the electrical structure that transmits impulses between the upper and lower chambers of the heart.
		Ventricular tachycardia is an arrhythmia that originates in the pumping chambers, or the ventricles.
		Because it is so rapid, and is occurring in a damaged heart, and because the electrical sequence does not follow the normal pattern, the heart may not function properly or efficiently and low blood pressure may result.

	Heart Arrhythmia Introduction & Symptoms
		Practically everyone experiences some version of an arrhythmia on occasion, usually in the form of a mild palpitation or a "skipped" heartbeat.
		There are two main categories of arrhythmia: tachycardia, meaning too fast a heartbeat, and bradycardia, meaning too slow a heartbeat.
		In fact, most cases of sudden cardiac death are due to ventricular arrhythmias, not heart attack, as was once thought.
