Safety and Efficacy Study of the First Domestically Produced FireMagic™ PreciSense™ 3D Microelectrode Ablation Catheter Therapy for Rapid Arrhythmia With Tissue Temperature Measurement Function

Criteria the registry did not label

• 1\. Inclusion Criteria
• Patient age between 18 and 75 years old, male or non-pregnant female;
• Confirmed diagnosis of supraventricular tachycardia or atrial fibrillation requiring catheter radiofrequency ablation surgery;
• Signed informed consent form approved by the ethics committee;
• Willingness to undergo follow-up and evaluation as required by the protocol.
  • 2\. Exclusion Criteria Include:
• Exclusion criteria for atrial fibrillation patients:
  • Patients should not participate in this study if any of the following conditions apply:
  • Left atrial size ≥50 mm, left ventricular ejection fraction ≤40%;
  • Left atrial thrombus;
  • History of atrial septal repair or atrial myxoma;
  • History of cerebrovascular disease within the past 3 months (including stroke or transient ischaemic attack);
  • Cardiovascular events within the past 3 months (including acute myocardial infarction, coronary artery intervention or bypass surgery, artificial valve replacement or repair, or atrial or ventricular incision);
  • Acute or severe systemic infection;
  • Severe liver or kidney disease;
  • Significant bleeding tendency or haematological disorders;
  • Patients with other conditions deemed inappropriate for participation in this trial by the investigators.
• Exclusion criteria for patients with ventricular tachycardia and supraventricular tachycardia:
  • Patients should not participate in this study if any of the following conditions apply:
• Left atrial size ≥50 mm and left ventricular ejection fraction ≤40%;
• History of atrial septal defect repair or atrial myxoma;
• Patients with cerebrovascular disease within the past 3 months (including stroke or transient ischaemic attack);
• Patients with cardiovascular events within the past 3 months (including acute myocardial infarction, coronary artery intervention or bypass surgery, artificial valve replacement or repair, or atrial or ventricular incision);
• Patients with acute or severe systemic infection;
• Patients with severe liver or kidney disease;
• Patients with a significant tendency to bleed or haematological disorders;
• Patients with other conditions deemed by the investigator to be unsuitable for participation in this trial.
