The finding could benefit African-Americans by making it possible to detect who is at increased risk for developing arrhythmia and allowing those affected to take preventive measures. The study is one of the first in which researchers have been able to discern how genetics influences arrhythmia risk across a range of populations of people who originated from different geographic regions. Mark T. Keating In an article published in the August 23, 2002, issue of the journal Science , the research team led by HHMI investigator Mark T. Keating reported that 13.2 percent of African-Americans in the study carried an altered form of the gene . This gene codes for a protein called a sodium channel, a molecular pore that initiates heartbeats by allowing sodium to flow across the membrane of the cardiac muscle cell.

Cardiac Psychiatry Program What is an arrhythmia? An arrhythmia (also called dysrhythmia) is an abnormal rhythm of the heart, which can cause the heart to pump less effectively. Arrhythmias can cause problems with contractions of the heart chambers by: Not allowing the chambers to fill with an adequate amount of blood, because an electrical signal is causing the heart to pump too fast. Not allowing a sufficient amount of blood to be pumped out to the body, because an electrical signal is causing the heart to pump too slowly or too irregularly. In any of these situations, the heart may not be able to pump an adequate amount of blood to the body with each beat, due to the arrhythmia's effects on the heart rate. The effects on the body are often the same, whether the heartbeat is too fast, too slow or too irregular. What are the symptoms of arrhythmia?

Nearly five decades later, we continue to lead in the field through the breadth and depth of our experience and our continued involvement with investigative trials for new and better arrhythmia treatments. Matching treatment to cause At Montefiore, we offer a thorough understanding of arrhythmia and the most effective means of treating its different forms. Arrhythmias can be divided into two categories, each with its own recommended treatments: Slow heart rhythms (brachycardia) may not require any intervention or, if they are significant enough, may require implanting of a pacemaker. Rapid heart rhythms (tachycardia) are often less serious, as they usually occur in people without heart disease.

Even those individuals undergoing highly technical and complex procedures, such as implantation of a defibrillation device, often require only an overnight stay. Most of our procedures have a serious complication rate of only 1 to 2 percent. Leader in diagnostic developments At Montefiore, we are pioneers not only in treatment but also in our use of the most sophisticated diagnostic advances. These include: Mapping system: Groundbreaking technology used by our electrophysiologists to locate the exact location of a heart problem.

Home Medical Dictionary Contact Us About Us ... Arrhythmia Arrhythmia Arrhythmia is any variation from the normal rhythm of the heartbeat. The heart rate at rest is usually between 60 and 100 beats per minute. Much lower rates may be normal in young adults, particularly those who are physically fit. Variations in heart rate are normal. The heart rate responds not only to exercise and inactivity but also to such factors as pain and anger. Only when the heart rate is too fast or too slow or when the electrical impulses travel in abnormal pathways is the heartbeat considered abnormal. Such rhythms may be regular or irregular. Symptoms of Arrhythmia How a patient describes his or her arrhythmia symptoms often helps the doctor diagnose an arrhythmia and determine how serious it is. The most important considerations are whether the: Heartbeats are fast or slow, regular or irregular or short or long Person feels dizzy, light-headed, faint or even loses consciousness Person is experiencing chest pain, shortness of breath or other unusual sensations along with the palpitations Palpitations happen when the patient is at rest or only during strenuous or unusual activity Palpitations start and stop suddenly or gradually Diagnosis of Arrhythmia Techniques for finding the exact nature of arrhythmia include: Electrocardiography (EKG) is the main technique for detecting arrhythmias. This test can provide a picture of the arrhythmia. An EKG shows the heart rhythm over a brief time. Often, however, arrhythmias come and go.
