The study is a prospective, multi-center, non-randomized, unblinded worldwide pre-market clinical study. The purpose of the study is to provide data demonstrating the safety and effectiveness of the PulseSelect™ PFA System for the treatment of atrial fibrillation (AF). The study will also provide first in human insights into clinical safety and device function of the PulseSelect PFA System for pulmonary vein isolation (PVI) as a treatment for AF. To this end, the clinical study has been designed into phases (Pilot and Pivotal), with each phase comprising a separate data set that will be analyzed and reported on per the below objectives.

Safety: Number of Participants With at Least One Primary Safety Event
Primary safety events are: Within 6 months post-ablation: * Pulmonary vein stenosis (≥70% diameter reduction) * Phrenic nerve injury/diaphragmatic paralysis (ongoing at 6 months) * Atrioesophageal fistula Within 30 days of ablation procedure: * Cardiac tamponade/perforation * Cerebrovascular accident * Major bleeding requiring transfusion * Myocardial infarction * Pericarditis requiring intervention * Transient ischemic attack * Vagal nerve injury resulting in esophageal dysmotility or gastroparesis * Vascular access complications requiring intervention * Systemic/pulmonary embolism requiring intervention * Pulmonary edema * Death * Any PulseSelect PFA System-related or PFA procedure-related cardiovascular and/or pulmonary adverse event that prolongs or requires hospitalization for more than 48 hours (excluding recurrent AF/AFL/AT)
Time frame: up to 6 months
Effectiveness: Number of Participants With Treatment Success.
Treatment success is defined as freedom from treatment failure. The study requires 24-hour Holter monitoring at 6 and 12 months in addition to weekly and symptomatic patient activated ambulatory monitoring transmissions through 12 months, and 12-lead ECGs at all follow up visits. Treatment failure is defined as any of the following components: * Acute procedural failure * Documented AF/AT/AFL on Holter/patient activated ambulatory monitoring/12-lead ECG after the 90-day post-ablation blanking period. * Any subsequent AF surgery or ablation in the left atrium, except for one repeat PVI ablation using PFA within the 90-day blanking period. * Direct current cardioversion for atrial tachyarrhythmia recurrences after the 90-day blanking period. * Class I or III antiarrhythmic drug (AAD) dose increase from the historic maximum ineffective dose (prior to the ablation procedure) or initiation of a new Class I or III AAD after the 90-day blanking period.
Time frame: up to 12 months
Quality of Life - Change in EQ-5D Score
Change in EQ-5D score (12-month score - baseline score). The Euroqol EQ-5D questionnaire (5L version) is a standardized instrument for measuring general health status. The Euroqol EQ-5D questionnaire (which consists of a 5-question survey and a visual analog scale) has a composite score based on the 5-question survey that ranges from 0 (least healthy) to 1 (most healthy).
Time frame: Baseline to 12 months post-ablation
Quality of Life - Change in AFEQT Score
Change in AFEQT score (12-month score - baseline score). The AFEQT questionnaire is an atrial fibrillation (AF) specific health-related quality of life questionnaire to assess the impact of AF on a subject's life. The overall score ranges from 0 - 100, with 0 corresponding to complete disability and 100 corresponding to no disability
Time frame: Baseline to 12 months post-ablation
