“…Rhythm control is recommended for younger patients with recent-onset or paroxysmal AF and those with shorter duration AF (≤ 48 h) [6,9]. Although existing evidence does not show one approach to be clearly superior to the other [10][11][12][13][14][15], in AF patients with distressing symptoms and/or seriously compromised cardiac function, it is of particular interest that cardioversion be achieved rapidly [5][6][7][8]16], as delayed cardioversion may worsen AF-associated symptoms and promote structural remodeling of the atria [17]. While various cardioversion therapies exist, their limitations, including limited use in certain comorbid patients, drug-drug interactions, and slow cardioversion rates, highlight the need for new treatments that are safer, more effective, and more timely in action [6,[18][19][20][21][22][23][24][25][26][27][28].…”
