First author/Year of publication Definition of POAF Monitoring of POAF
Jideus/2001 [15] The absence of consistent P waves before each QRS complex and with an irregular ventricular rate, lasting 30 seconds or longer Twenty-four hour Holter ECG performed on the first 4 consecutive days, or until clinically documented sustained atrial fibrillation
