Next Heart Disease: Abnormal Heart Rhythm What causes an arrhythmia? What are the types of arrhythmias? What are the symptoms of arrhythmias? How are arrhythmias diagnosed? ... What is heart surgery? An arrhythmia (also called dysrhythmia) is an irregular heartbeat. Heart rates can also be irregular. A normal heart rate is 50 to 100 beats per minute. Arrhythmias and abnormal heart rates don't necessarily occur together. arrhythmias can occur with a normal heart rate, or with heart rates that are slow (called bradyarrhythmias less than 60 beats per minute). arrhythmias can also occur with rapid heart rates (called tachyarrhythmias faster than 100 beats per minute). What Causes an Arrhythmia? Arrhythmias may be caused by many different factors, including: Coronary artery disease Electrolyte imbalances in your blood (such as sodium or potassium). Changes in your heart muscle. Injury from a heart attack Healing process after heart surgery.

An arrhythmia is a change from the normal rate or control of the heart’s contractions. Where the changes are under the influence of the SA node, the term sinus arrhythmia is used. These are described under: Sinus Rhythms All other arrhythmia occur independently to the SA node. Blocks are broken connections within the heart’s conduction system which cause arrhythmia Delays are long periods between beats Premature beats are contractions of the heart that occur before the SA node has fired Rhythms that are generated outside of the SA node are separated into supraventricular and ventricular depending on their origin. Cardiac Arrhythmia Sinus Rhythms Blocks Delays Premature Beats ... Patient Information

Several forms of cardiac arrhythmia are life-threatening and a medical emergency Frequency too high/low A rhythm of the heart at a rate of more than 100 beats/minute is considered a tachycardia . If the ventricles of the heart experience tachycardia for a sustained period of time, there can be deleterious effects. Individuals may sense a tachycardia as a pounding sensation of the heart; this is known as "palpitations". However, strictly speaking, palpitations are any sensation of an individual's own heart beat, and can occur at rates less than 100 beats/minute. The causes of tachycardias are numerous, and include stress, ingested or injected substances (ie:

Various arrhythmias can be symptoms of serious heart disorders; however, they are usually of no medical significance except in the presence of additional symptoms. The heart's rhythm is controlled by an electrical impulse that is generated from a clump of tissue on the right atrium called the sinoatrial node, often referred to as the heart's natural pacemaker. It travels to a second clump of tissue called the atrioventricular node and then to the ventricles. Bradycardia, or slow heartbeat, is often present in athletes. It may, however, indicate conduction problems, especially in older people. In one type of bradycardia, called sinoatrial or atrioventricular block, or heart block, rhythm can be maintained by implanted electrodes that act as artificial pacemakers Tachycardia, or heartbeat faster than 100 beats per minute in the adult, can be precipitated by drugs, caffeine, anemia, shock, and emotional upset. It may also be a sign of overactivity of the

Other Resources Arrhythmia Arrhythmia Signs and Symptoms Diagnosis Treatment Signs and Symptoms An abnormal heart rhythm is a change in the speed or pattern of the heartbeat the heart may beat too slowly, too rapidly or irregularly. When the heart beats too slowly, too little blood is pumped out to the rest of the body. When the heart beats too quickly, it cannot fill completely with blood so the body doesn't receive the blood volume it needs to function properly. Slow heart rates are called bradycardias. Fast heart rates are called tachycardias. The "normal" number of heartbeats varies with age. The heart beats about 140 times a minute in a newborn, compared to 70 times a minute in an older child at rest. The "normal" heart rhythm also is not constant. See more information about the heart's electrical system. A heart that beats too fast or too slow can cause: Palpitations, which can be skipping, fluttering or pounding in the chest Fatigue Chest pressure or pain Shortness of breath Fainting, called syncope

Electrophysiology and Arrhythmia Service Electrophysiology and Arrhythmia Service The Johns Hopkins Electrophysiology Service exists to provide heart patients with timely, accurate diagnoses and therapies. They do this by using advanced technologies and working as a team with you, your family, and your physician to help you continue or return to your normal daily activities as soon as possible. The Electrophysiology Service began in the early 1970s with two goals: to provide leading edge care for patients with irregular heart rhythms (arrhythmias) and to do research to determine the cause of arrhythmias and develop treatments for patients who have heart rhythm problems. As the first such service in Maryland, and one of the first in the United States, the Johns Hopkins Electrophysiology Service rapidly took on a leadership role. An early success was the development and use of the first automatic implantable defibrillator, also known as implantable cardiac defibrillators (ICDs). In 1980, Dr. Levi Watkins first implanted this device, which was invented by Drs. Michel Mirowski and Morton Mower, in a patient who had experienced numerous episodes of life-threatening arrhythmias. Since then, ICDs have saved hundreds of thousands of lives and are recognized as the most effective treatment to prevent sudden cardiac death. Currently, doctors in the Electrophysiology Service are focusing their efforts on catheter ablation, a technique that can cure abnormal heart rhythms. Other areas of clinical and research interest include the causes and treatment of atrial fibrillation and syncope (fainting), the prevention and treatment of problems that may cause cardiac death, as well as further perfecting pacemaker and ICD therapy.

Overview Our Team Research and Clinical Trials Resources ... Two Hearts are Better than One for Toddler at Lucile Packard Children’s Hospital at Stanford Electrophysiology and Arrhythmia Services Electrophysiology (EP) is a subspecialty of cardiology that examines the electrical behavior of the heart by recording electrical activity from within the heart chambers. One catheterization laboratory procedure is called electrophysiology (EPS) study, which specialized cardiologists use to diagnose or treat a rhythm problem of the heart. Doctors thread specialized catheters through blood vessels in the patient's leg or neck, up to pace the heart and to measure and record the electrical activity of the heart. When doctors detect abnormal electrical pathways, which can cause dangerous heart rhythm abnormalities, they can do another procedure called radiofrequency (RF) ablation to cure the problem. During RF ablation, the doctors use a special mapping catheter, which is positioned precisely, to deliver radio frequency energy to a very tiny area of the heart, destroying the abnormal pathway or tissue. The Pediatric Arrhythmia Center at Stanford and UCSF is directed by Dr. George Van Hare. It is based at both Packard Children's Hospital and UCSF Medical Center, and includes faculty and staff at both facilities. Dr. George Van Hare performed the first pediatric radiofrequency catheter ablation in the United States.

Human Brain Is Still Evolving One Shot: Researchers Capture Pictures of Fusion Events That Enable Sperm to Penetrate Egg's Coating Human Y Chromosome Preserves Itself Better Than the Chimp Y More October 01, 2004 Researchers Pinpoint Cause of a Severe Cardiac Arrhythmia Howard Hughes Medical Institute researchers have pinpointed the genetic cause of a devastating but rare childhood disorder, called Timothy syndrome, which underlies a form of severe cardiac arrhythmia. The research shows that the syndrome results from spontaneous genetic mutations that interfere with calcium channels that regulate the excitation and contraction of the heart. In defining the precise nature of the molecular abnormality, however, the researchers have also identified a class of drugs that they hope will alleviate the arrhythmia. Mark T. Keating Timothy syndrome may also cause a form of autism in those affected, and there is the possibility that understanding more about the nature of these calcium channel defects could improve understanding of autism, which affects 200,000 to 400,000 children in the United States. Calcium channels are pore-like proteins that nestle in cell membranes and control the flow of calcium into and out of the cell. Calcium is one of the most important signaling molecules in the body, and perturbing calcium transport can cause a wide range of disorders. Howard Hughes Medical Institute investigator Mark T. Keating and his colleagues reported in the October 1, 2004, issue of the journal
