The primary objective of this study was to evaluate the clinical feasibility, safety, and surgical characteristics of the EasyStars™ High Density Mapping Catheterin in patients with complex arrhythmias.
Detailed description
The primary objective of this study was to evaluate the clinical feasibility, safety, and surgical characteristics of the EasyStars™ High Density Mapping Catheterin in patients with complex arrhythmias. In addition, the study assessed the catheter's usability and mapping performance through postoperative physician feedback.

Eligibility
Inclusion criteria
1. Clinical diagnosis: Ventricular tachycardia (VT) * Inclusion criteria: 1. Patients aged between 18 and 80 years; 2. Confirmed diagnosis of ventricular tachycardia (VT) via electrocardiogram (ECG) or 24-hour Holter monitoring; 3. The patient has experienced at least one episode of VT in the past 6 months and exhibits symptoms of sustained or paroxysmal ventricular tachycardia; 4. The patient meets the criteria for ablation surgery and has clear indications for ablation; 5. The patient is in good general health and able to tolerate surgery (no severe underlying heart disease, such as severe heart failure or severe coronary artery disease); 6. Voluntarily participates and signs an informed consent form. *
Exclusion criteria
1. Uncontrolled heart failure (New York Heart Association functional class III-IV); 2. History of acute or progressive myocardial infarction; 3. Severe pulmonary, hepatic, or renal disease; 4. Valvular heart disease or congenital heart disease; 5. Excessive use of medications or medication intolerance (e.g., beta-blockers, antiarrhythmic drugs); 2. Clinical diagnosis: Atrial tachycardia (AT) * Inclusion criteria: 1. Patients aged 18 to 80 years; 2. Diagnosed with atrial tachycardia (AT) by electrocardiogram (ECG) or Holter monitoring; 3. Patients presenting with clinical symptoms such as palpitations, chest tightness, or fatigue; 4. Patients diagnosed with persistent or paroxysmal atrial tachycardia and meeting the criteria for ablation therapy; 5. Patients who voluntarily participate and sign an informed consent form. *
