41. Hospital Practice: Cardiac Arrhythmia Care and management of atrial fibrillation, atrial flutter, supraventricular tachycardia, ventricular arrhythmia and a look at syncope. http://www.hosppract.com/issues/1999/0901/gold.htm

Cardiac Arrhythmia: Current Therapy MICHAEL R. GOLD and MARK E. JOSEPHSON University of Maryland and Harvard University Rhythm disturbances can range from the harmless to the life-threatening, and treatment varies accordingly, from watchful waiting to emergency intervention. Traditional antiarrhythmic medications have largely been supplanted by newer agents; pharmacologic therapy is giving way to device-based treatment, including pacemakers, defibrillators, and catheter ablation. Dr. Gold is Director, Cardiac Electrophysiology Service, and Associate Professor of Medicine, University of Maryland School of Medicine, Baltimore. Dr. Josephson is Professor of Medicine, Harvard Medical School, and Director, Harvard-Thorndike Electrophysiology Institute, Beth Israel Deaconess Medical Center, Boston. During the past few years, the treatment of many cardiac arrhythmias has tended to move away from drug therapy and toward device-based therapy. The latter may involve pacemakers, implantable defibrillators, or catheter ablation, depending on the type of arrhythmia. When drug therapy is the preferred route, the agents used are different from those selected several years ago. The treatment changes affect the management of the most common arrhythmias seen in primary care practice, including atrial fibrillation, atrial flutter, supraventricular tachycardia, and ventricular arrhythmia. Atrial Fibrillation The prevalence of atrial fibrillation increases with age; this arrhythmia is most often seen in patients older than 65 years. Atrial fibrillation is typically associated with some form of cardiovascular disease, such as hypertension, coronary artery disease, or valvular heart disease, but it can also occur secondary to metabolic disorders such as thyrotoxicosis. In a minority of young patients, there is no obvious cause, a condition known as lone atrial fibrillation.

42. KPCC - KPCC Reveals President Bush Has A Heart Arrhythmia KPCC Reveals President Bush Has A Heart arrhythmia White House Did Not DiscloseAfter Pretzel Incident That Mr. Bush Has Sinus Bradycardia © 2002 David Robb http://www.kpcc.org/features/bush_special.html

KPCC Special Report KPCC Reveals President Bush Has A Heart Arrhythmia White House Did Not Disclose After Pretzel Incident That Mr. Bush Has Sinus Bradycardia President Bush's low heart rate is an arrhythmia called sinus bradycardia that makes him more prone to fainting when he gags or chokes. It's most likely why he passed out January 13 in the highly publicized pretzel incident. Bradycardia means that the president's heart beats more slowly than the average person's heart. It gets its name from the Greek bradu-, from bradus (slow) + kardi (heart). 'Sinus' refers to the sinus node, which is the heart's natural pacemaker. The press has reported that Bush has a slow heart rate. In August, after President Bush underwent a physical exam, the White House reported that his resting heart rate was 43 beats per minute. On Jan. 14, the day after the president's fainting episode, the Los Angeles Times reported that Bush has "a resting pulse rate of 35 to 45 beats per minute, which medical personnel consider extremely low even for a well-trained athlete." White House spokesman Ari Fleischer told reporters the day after Bush's fainting spell that the president's resting heart rate was 51 beats per minute. But up until now, the White House has not volunteered, and the media have not reported, that the president's slow heart rate is technically a heart arrhythmia called sinus bradycardia. But now the White House is confirming this.

43. Treating Heart Arrhythmia During Pregnancy Guidelines for treating arrhythmias in women during pregnancy. http://www.swmed.edu/home_pages/news/arrhyth.htm

The University of Texas Southwestern Medical Center at Dallas Treating heart arrhythmia during pregnancy can be done safely Contact: Bridgette Rose McNeill e-mail: Bmcnei@mednet.swmed.edu DALLAS December 12, 1995 Pregnant women often swoon. But it shouldn't be taken lightly. In some instances, these episodes are symptoms of a heart disturbance. Arrhythmia an irregular heart rhythm can develop for the first time during pregnancy or become worse in women who already have an abnormal rhythm. "It is not uncommon for pregnant women to become lightheaded or to faint," said Dr. Richard Page, an associate professor of internal medicine at UT Southwestern Medical Center at Dallas. "Most of the time it has to do with other changes in the blood flow and circulation during pregnancy, but sometimes it is due to a heart-rhythm problem that needs to be addressed." Treating such a patient is filled with potential complications and complexities as well as gratification, Page said in a recent article, "Treatment of Arrhythmias During Pregnancy," published in the American Heart Journal Arrhythmia disturbances impair the heart's ability to pump blood adequately. "That's why someone might pass out, for example; there's not adequate blood flow to the brain," said Page, who is also director of the Clinical Cardiac Electrophysiology Unit at UT Southwestern and at Parkland Memorial Hospital.

44. When Heartbeats Go Haywire: New Treatments Can Save Lives An Indepth discussion on ventricular arrhythmias and new drugs and devices in curbing deaths from this disorder. http://www.fda.gov/fdac/features/1997/397_hart.html

When Heartbeats Go Haywire: New Treatments Can Save Lives by Margie Patlak Two-time Olympic gold-medalist skater Sergei Grinkov shocked the world in fall 1995, when he collapsed on the ice rink and died hours later at the young age of 28. A blood clot that blocked blood flow to his heart triggered it to quiver instead of beat. Medical technicians were unable to restore a normal heart rhythm, and by the time he reached a hospital, Grinkov's heart had stopped beating altogether. Grinkov suffered what is known as ventricular fibrillation. This inefficient and deadly quivering of the heart is one of several types of irregular heartbeats, or arrhythmias, that afflict the lower chambers, called the ventricles, of the heart. Not all arrhythmias are ventricular; some, for example, arise from the upper chambers of the heart. Ventricular arrhythmias often occur in people with various forms of heart disease and, according to the American Heart Association, cause most cases of sudden cardiac death. But new drugs and devices show promise in curbing the number of deaths from this condition. These new treatments, approved by the Food and Drug Administration, include a longer-acting form of an antiarrhythmia drug, a wide availability of portable and implantable electrical devices that can spark a return to normal heart rhythm, and techniques for destroying heart tissue that triggers ventricular arrhythmias. Heart of the Matter Not much bigger than a fist, the human heart beats 100,000 times each day, sending about 2,000 gallons of blood coursing through vessels, which, laid end-to-end, would be long enough to circle the earth more than twice.

PIDL Home/ Contents Development Nutrition Acute Illness ... Psychosocial Cardiology IRREGULAR HEART RHYTHM IN CHILDREN Irregular heart beat is an occasional finding in an otherwise healthy child that requires decision making on the pediatrician's part. In general, there are 4 types of EKG abnormalities causing irregular heart rate in these patients: 1. Vagal arrhythmia 2. Premature atrial contractions (PAC) 3. Second degree heart block, Type I (Wenckebach) 4. Premature ventricular contractions (PVC) Vagal arrhythmia refers to the normal variations in vagal tone that are associated with changes in sinus rate, or wandering pacemaker (from high right atrium to low right atrium), or junctional rhythm which self terminates. Studies have shown that up to 40% of normal children have an intermittent junctional rhythm on holter monitoring during sleep. If asymptomatic, these problems require no further workup; if there are symptoms (eg syncope) holter monitoring and exercise testing are warranted. Very rarely, these patients require pacemakers. PAC's are common up to 20% of normal children have occasional PAC's on 24 hour holter monitoring. If there are no symptoms suggestive of supraventricular tachycardia, no further workup or treatment are needed. Precipitating factors of frequent PAC's may include hyperthyroidism, myocarditis, and sympathomimetic medications.

Each perceived thump of the heart actually consists of two beats, one by the upper chambers, or atria, and one by the lower chambers, or ventricles. The contractions are triggered by electrical impulses originating in the sinoatrial node, a specialized group of cells located in the heart's right atrium. More In-Depth Info: Heart Center Any disturbance in the normal beating pattern of the heart is called an arrhythmia, or irregular heartbeat. Practically everyone experiences some version of an arrhythmia on occasion, usually in the form of a mild palpitation or a "skipped" heartbeat. (In fact, what feels like a skipped beat is really an early beat, weak enough not to be felt, then a one- or two-second pause, followed by a relatively forceful beat; the delay between beats feels like a skip.) Mild, isolated disturbances of this sort are normally harmless. A recurrent arrhythmia, on the other hand, should be checked by a physician.
