Atrial fibrillation (AF) is the most common cardiac rhythm disorder, affecting 1.5 to 2 per cent of the general population in the developed world.
    
"AF episodes are accompanied by chest pain, dyspnoea and dizziness. These symptoms are unpleasant and patients feel anxious, worried and stressed that an AF episode will occur," said Maria Wahlstrom from Karolinska Institute in Sweden.
    
There is no cure for AF, and management focuses on relief of symptoms and the prevention of complications such as stroke using cardioversion, ablation and medication, researchers said.
    
Patients with paroxysmal AF experience episodes of AF that usually last less than 48 hours and stop by themselves, although in some patients they can last up to seven days. The current study included 80 patients with paroxysmal AF who were randomised to yoga or a control group that did not do yoga.
