It has been revealed in a recent study review that an abnormal heart rate might be riskier for women's health than men. Atrial fibrillation (AF) is one of the major factors of cardiovascular diseases worldwide and women are more susceptible to this which might lead to death.

AF results to an irregular or in some cases, a faster pulse which is caused by high BP, heart valve disease, a hyper thyroid gland and too much consumption of alcohol, according to the British Heart Foundation. AF can be felt through palpitations, feeling tired, fainting feeling and dizziness.

However, the recent study review found out that women are more prone to AF after the researchers analyzed 4.3 million patients and examined 30 other studies. The study also reveals that women with AF have a 12 percent higher chance of death caused by a heart disorder. The reason of the higher risk for women cannot be identified by the researchers, according to the British Medical Journal.

Connor Emdin of University of Oxford's George Institute for Global Health, one of the review writers, noted that this shows how women experience heart conditions differently. "This study adds to a growing body of literature showing that women may experience cardiovascular diseases and risk factors differently than men," Emdin said, according to Web MD.

British Heart Foundation's June Davison also noted that when providing medical care, effects on gender should also be considered. "It is important that healthcare services for the prevention and treatment of AF take into account the different effects of gender on the condition," Davison said, according to BBC. "More research is needed to find out more about the underlying causes of these differences."
