Exploratory Safety and Effectiveness Evaluation of Pulsed Field Ablation (PFA) by Balloon Catheter With TRUPULSE Generator for Treatment of Paroxysmal Atrial Fibrillation (PAF)

Inclusion Criteria: * Diagnosed with symptomatic Paroxysmal Atrial Fibrillation (PAF) defined as 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) * 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 \[body mass index more than {\>} 40 kilogram per square meter {kg/m\^2}\], renal insufficiency \[with an estimated creatinine clearance less than {\<}30 milliliter {mL}/minute {min}/1.73 meter {m}\^2\]) * Previous left atrium (LA) ablation or surgery * Participants known to require ablation outside the pulmonary vein (PV) region (example, atrioventricular reentrant tachycardia, atrioventricular nodal re-entry tachycardia, atrial tachycardia, ventricular tachycardia and Wolff-Parkinson-White) * Previously diagnosed with persistent AF (\>7 days in duration) * Severe dilatation of the LA (left anterior descending artery \[LAD\] \>50 millimetre \[mm\] antero-posterior diameter or left atrium volume index \[LAVi\] \>48 \[mL/m\^2\] in case of transthoracic echocardiography \[TTE\])
