Working to prevent Sudden Cardiac Death by promoting a better understanding of Arrhythmias through education and research. Texas Arrhythmia Institute Thank you for being the first or one of the first to so thoughtfully put in print so many things that are important and needed to be stated. Jeff Baerman, MD It is time that a person in a position of academic authority question what is being propagated in our journals and profession. David Kessler, MD Ablation for Atrial Fibrillation: Are Cures Really Achieved? A TXAI commentary on ablation studies by medical professionals that was recently published in the Journal of the American College of Cardiology. Dr. Pacifico, I read the abstract of your editorial and agree with what I read. My wife was injured during a failed PVA in 2002 and since then I've done a lot of research. It leads me to believe that there was more hype than substance to the whole ablation phenomenon and that safety and effectiveness were never really proven. The steep learning curve cost my wife plenty. The Clinical Competence Statement on Invasive Electrophysiology Studies issued the year my wife had her ablation urges caution: "In any event, it remains increasingly critical that the practicing physician acquire and maintain an understanding of relevant first principles of electrophysiology. Although it is exciting, it should be kept in mind that the technology facilitates the application of those fundamental principles of electrophysiology only for the benefit of arrhythmia patients."

What's the treatment? Arrhythmia: A Problem With Your Heartbeat Printer-friendly version Email this article What is an arrhythmia? An arrhythmia is a change in the rhythm of your heartbeat. When the heart beats too fast, it's called tachycardia. When it beats too slow, it's called bradycardia. An arrhythmia can also mean that your heart beats irregularly (skips a beat or has an extra beat). At some time or another, most people have felt their heart race or skip a beat. These occasional changes can be brought on by strong emotions or exercise. They usually are not a cause for alarm. Arrhythmias that occur more often or cause symptoms (see the box below) may be more serious and need to be discussed with your doctor. Return to top What causes an arrhythmia? What are the symptoms of arrhythmia? Call your doctor if you have any of these symptoms, especially if you have heart disease or have had a heart attack. Palpitations or rapid thumping in your chest Feeling tired or light-headed Passing out Shortness of breath Chest pain The heart has 4 chambers. The walls of the heart contract to push blood through the chambers. The contractions are controlled by an electrical signal that begins in the heart's natural "pacemaker" (called the sinoatrial node). The rate of the contractions is influenced by nerve impulses and hormones in the blood. A problem in any of these can cause an arrhythmia.

Rheumatic Heart Disease Links Email Mama The heart is a pump that functions by pushing the blood through its four chambers. The blood is "pushed" through in a controlled sequence of muscular contractions. The sequence is controlled by bundles of cells which control the electrical activity of the heart. When the sequence is disturbed, heart arrhythmias occur. Arrhythmias are abnormal rhythms of the heart . They cause the heart to pump blood less effectively. Most cardiac arrhythmias are temporary and benign. Most temporary and benign arrhythmias are those where your heart skips a beat or has an extra beat. The occasional skip or extra beat is often caused by These occasional changes can be brought on by strong emotions or exercise. Nonetheless, some arrhythmias may be life-threatening and require treatment. Arrhythmias can be divided into two main categories ventricular and supraventricular . Supraventricular arrhythmias occur in the heart's two upper chambers called the artium. Ventricular arrhythmias occur in the heart's two lower chambers called the ventricles. Supraventricular and Ventricular arrhythmias are further defined by the speed of the heartbeats: very slow, very fast and fast uncoordinated. A very slow heart rate is called

Conduction system of the heart Alternative names Return to top Dysrhythmias; Abnormal heart rhythms Definition Return to top An arrhythmia is any disorder of heart rate or rhythm. Causes, incidence, and risk factors Return to top Arrhythmias are caused by a disruption of the normal electrical conduction system of the heart. Normally, the 4 chambers of the heart (2 atria and 2 ventricles) contract in a very specific, coordinated manner. When the heart beats faster than normal, it is called tachycardia. Bradycardia is a slower-than-normal rhythm. The electrical impulse that signals the heart to contract in a synchronized manner begins in the sinoatrial node (SA node), which is the body's natural pacemaker. The signal leaves the SA node and travels through the 2 upper chambers (atria), stimulating them to contract. Then the signal passes through another node (the AV node), and finally, through the lower chambers (ventricles), stimulating them to contract in synchrony.

Thus, by age 70, 10% of individuals with a history of hyperthyroidism have atrial fibrillation while only 5% of those who lack a history of a thyroid problem have the condition. A combination of factors may explain these observations. Excess thyroid hormone stimulates the heart to go faster and may precipitate irregular heart rhythm disturbances, particularly in patients who are predisposed to this occurring.
