“…For the past years, a series of sophisticated methods have been developed to tackle the challenges of AF detection (Kikillus et al, 2007; Couceiro et al, 2008; Babaeizadeh et al, 2009; Yaghouby et al, 2010; Larburu et al, 2011; Parvaresh and Ayatollahi, 2011). Two classes of AF detection methods, the atrial activity analysis-based (Artis et al, 1991; Slocum et al, 1992; Lake and Moorman, 2011; Zhou et al, 2014; Ladavich and Ghoraani, 2015) and the ventricular response analysis-based (Moody and Mark, 1983; Tateno and Glass, 2001; Dash et al, 2009; Park et al, 2009; Huang et al, 2011; Lian et al, 2011; Yaghouby et al, 2012; Lee et al, 2014) method, attract the interest of the most of studies. The first category methods utilize the absence of P waves or the presence of f-waves for diagnosis.…”
