The study was conducted on 1.2 million people, and proved that every additional 3 cm in length increases the risk by 3% compared to the risks to those with an average length of 170 cm.
Scientists have analyzed their DNA, say that genes are responsible for the disorder, and called on doctors to regularly examine tall stalkers to diagnose the deadly condition early.
Previous studies have suggested that taller people are at greater risk because "too much of their heart surface is not working properly."
Atrial fibrillation is a condition in which the heart rhythm is abnormally fast, increasing the risk of stroke by five times.
The study showed that genetic variables associated with length also related to irregular heartbeat, and the results remained valid even after taking into account other factors that play a role in the development of the condition, such as high blood pressure.
