The goal of this observational study is to detect the long-term risk of a composite endpoint event in adult patients with ventricular tachycardia (VT) who are managed with catheter ablation or non-ablation management (including modern drug therapy and/or ICD therapy).

Inclusion Criteria:

• Sustained ventricular tachycardia (VT), defined as VT lasting ≥30 seconds or requiring intervention due to hemodynamic compromise within 30 seconds; or Clinically significant non-sustained VT (NSVT) where the treating clinician has determined that therapeutic intervention is necessary.

Exclusion Criteria:

• Concurrent participation in any interventional clinical trial that, in the judgment of the investigator, could interfere with the data collection or outcome assessment of this observational study.
