It causes someone to fall unconscious and stop breathing and unless treated with CPR, it is fatal. Among these cases, less than 1 percent of cardiac arrests occurred during or immediately after sexual activity, the study found. To determine whether sexual activity might trigger sudden cardiac arrest, researchers examined records on 4,557 cases of cardiac arrest in adults between 2002 and 2015 in a community in the northwestern United States. ANAHEIM, California, Nov. 12, 2017 -- Sexual activity is rarely associated with sudden cardiac arrest, a life-threatening malfunction of the heart's electrical system causing the heart to suddenly stop beating, according to preliminary research presented at the American Heart Association's Scientific Sessions 2017, a premier global exchange of the latest advances in cardiovascular science for researchers and clinicians.

 "While sudden cardiac arrest is a devastating condition with a high chance of death, the likelihood of this occurring during sexual activity … was extremely low," said Dr. Sumeet Chugh, medical director of the Heart Rhythm Center at the Cedars-Sinai Heart Institute in Los Angeles and senior author of the study. In the rare instances in which sex was linked with cardiac arrest, almost all of the cases — 94 percent — were in men, the study found: Among men, about 1 in 100 cases of cardiac arrest were linked with sex, compared with just 1 in 1,000 cases among women. org/ news/ sexual-activity-rarely-a-heart-stopping-activity?preview= 484c3df2e7b28ec0cff1233fd9c6768d

The study also found that, even though sudden cardiac arrest linked with sexual activity was usually witnessed by the person's partner, bystander CPR was performed in only one-third of cases. Dr Chugh said: "These findings highlight the importance of continued efforts to educate the public on the importance of bystander CPR for sudden cardiac arrest, irrespective of the circumstance." Cardiac arrest facts 
 
 Almost 90% of people who suffer out-of-hospital cardiac arrests die 
 
 Every minute without cardiopulmonary resuscitation (CPR) or defibrillation reduces someone's survival chances by 10% 
 
 CPR, especially if performed in the first few minutes of cardiac arrest, can double or triple a person's chance of survival 
 
 During CPR, you should push on the chest at a rate of 100 to 120 compressions per minute.
– Many men with heart disease fear that having sex could kill them, but new research shows the danger is slight. Researchers at Cedars-Sinai Heart Institute reported Sunday at an American Heart Association conference that only one in every 100 cases of sudden cardiac arrest in men occurred after sexual activity. But 94% of those victims had a history of heart disease, NBC News reports. The study, to be published in the Journal of the American College of Cardiology, was the first to look at whether sexual exertion can trigger a heart attack, notes Live Science. Fear of post-sex heart failure has been bolstered by plot lines on TV shows like Mad Men, but in reality, "the risk is very small," senior author Dr. Sumeet Chugh tells NBC. Chugh's team analyzed 4,557 cardiac arrests that occurred between 2002 and 2015, and found that 34 happened within one hour of sexual intercourse. Sudden cardiac arrest, which killed Tom Petty, takes place when an electrical impulse goes haywire and the heart stops beating. There are often no warning signs. Still, the danger is far greater for men: Only two of the heart attacks studied involved women. The majority of victims were middle-aged and African-American men, per the BBC. But CPR can make a life-or-death difference. CPR was performed in only one-third of cases studied, prompting Chugh to urge the "importance of (teaching) bystander CPR for sudden cardiac arrest, irrespective of the circumstance." Another study found that children as young as 6 can learn CPR, per the BBC. (A boy with an unusual condition went into cardiac arrest after biting into a hot dog.)
