Establishing content validity in a novel patient reported outcome measure for cardiac arrhythmia ablation patients

Table 1 Number of patients across arrhythmia substrates interviewed before and after their ablation procedure

Interviewed:	Total*	Atrial fibrillation (AF)	Supraventricular tachycardia	Atrial flutter	Ventricular ectopics
Pre ablation (male/female)	15 (5/10)	9 (4/5)	2 (0/2)	3 (1/2)	1 (0/1)
Post ablation (male/female)	14 (8/6)	10 (6/4)	2 (0/2)	2 (2/0)	0 (0/0)

*Total sample size = 25 patients (15 female / 10 male). Four patients who had previously received an ablation for paroxysmal AF were also awaiting a further ablation procedure for either paroxysmal AF (3 patients: 1 male, 2 female) or persistent atrial flutter (1 female patient). These patients were therefore classed as both pre and post-procedure at the time of interview.
