Scienceily Oct. 9, 2013 — An individual's race or ethnic background could be a determining factor when it comes to risk of atrial fibrillation, the most frequently diagnosed type of irregular heart rhythm, according to researchers at UC San Francisco. In a study to be published online October 8 and in the November 12 issue of Circulation, researchers discovered that self-described non-Hispanic whites are more likely to develop atrial fibrillation than people from other race or ethnic groups. "We found that consistently, every other race had a statistically significant lower risk of atrial fibrillation compared to whites," said senior author Gregory Marcus, MD, MAS, FHRS, an associate professor of medicine who specializes in electrophysiology in the UCSF Division of Cardiology. "So this suggests that white race is itself a risk factor for atrial fibrillation." The researchers studied the records of 14 million California patients who visited the emergency room, had outpatient services, or were hospitalized between 2005 and 2009. The patient sample included Caucasians, African Americans, Hispanics and Asian Americans. Previous research that established African Americans at lower risk for atrial fibrillation than whites, despite having more risk factors for atrial fibrillation, studied only Caucasians and African Americans. This raised the question as to whether African Americans were protected or whites were at increased risk, forming the foundation for the current study. "We were surprised to find that Asian Americans and Hispanics have similar relative decreases in atrial fibrillation risk as African Americans, suggesting there is some characteristic unique to whites that increases the likelihood of this abnormal heart rhythm," said first author Thomas A. Dewland, MD, a cardiac electrophysiology fellow in the UCSF Division of Cardiology. Atrial fibrillation is the most common cardiac arrhythmia. People over 40 years of age have a 26 percent lifetime risk of developing this abnormality, according to the Framingham Heart Study. "Presumably there may be a gene, or a set of genes, in European ancestry or some important behavior or environmental exposure in whites that increases the risk for atrial fibrillation," Marcus said. "Based on several analyses performed in the study, the risk is not related to existing cardiac conditions like high blood pressure or existing heart disease." In comparison to Caucasians, African Americans had 16 percent lower risk, Hispanics had 22 percent lower risk, and Asian Americans also had 22 percent lower risk for atrial fibrillation. "Despite the frequency with which we see this disorder in our clinical practice, our understanding of why certain patients are affected remains incomplete," Dewland said. "Continued research into how atrial fibrillation develops will allow us to better predict, treat, and ultimately prevent this rhythm abnormality."

My sister went to the hospital last week for ventricular tachycardia. She'd been having fainting spells and a racing pulse. Left untreated, her heart would've just crapped out before long. They had to do this nasty procedure. Stuck a catheter into her leg and snaked a camera up her descending aorta to look inside her heart. Then they stuck another tube up the same way to electro-fry some errant heart tissue. Then they shot her with adrenalin to try and induce the fibrilation and determine whether they got it all. She had to be fully awake without pain killers for the whole thing. She was screaming. She's all better now though. Twenty years ago they would've put her on anti-arhythmia drugs with a whole bunch of nasty side effects. "If an angry bigot assumes this bountiful cause of Abolition, and comes to me with his last news from Barbados, why should I not say to him, 'Go love thy infant; love thy wood-chopper: be good-natured and modest; have that grace; and never varnish your hard, uncharitable ambition with this incredible tenderness for black folk a thousand miles off. Thy love afar is spite at home.'" I knew this moron security guard who was beating some guy over the head with a .38 when it went off and he shot himself in the forearm. He had undergo the same procedure except dye was shot into him to see what damage there was to the blood vessels in his forearm. He said he was shrieking the entire time. "Have Brain, Will Travel

In the case of supraventricular tachycardia due a short circuit in the heart cardio docs are offering as an alternative to catheterized electrical burn either Bisoprolol or Diltrazem.
