A Study For Treatment Of Paroxysmal Atrial Fibrillation (PAF) With The THERMOCOOL SMARTTOUCH SF Catheter and TRUPULSE Generator

Inclusion Criteria: * Diagnosed with symptomatic paroxysmal atrial fibrillation (PAF) defined as atrial fibrillation (AF) that terminates spontaneously or with intervention within 7 days of onset. This PAF is considered to be symptomatic if symptoms related to AF are experienced by the participant * Selected for AF ablation procedure by pulmonary vein isolation (PVI) * Failed at least one antiarrhythmic drug (AAD) (class I to IV) as evidenced by recurrent symptomatic AF, or intolerable or contraindicated to the AAD * Willing and capable of providing consent * Able and willing to comply with all pre-, post- and follow-up testing and requirements. Exclusion Criteria: * Previously known AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause (example, documented obstructive sleep apnea, acute alcohol toxicity, morbid obesity {Body Mass Index greater than \[\>\] 40 kilograms per meter square \[kg/m²\]}, renal insufficiency (with an estimated creatinine clearance less than \[\<\] 30 milliliters \[mL\]/ minute \[min\]/1.73 meter square \[m2\] ) * Previous left atrium (LA) ablation or surgery * Patients known to require ablation outside the pulmonary vein (PV) region (example, atrioventricular reentrant tachycardia, atrioventricular nodal reentry tachycardia, atrial tachycardia, ventricular tachycardia and wolff-parkinson-white) * Previously diagnosed with persistent AF \[greater than (\>) 7 days in duration\] * Severe dilatation of the left atrium (LA) (Left anterior descending artery \[LAD\] \>50mm antero-posterior diameter in case of Transthoracic Echocardiography \[TTE\])
