Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other illness
- Presence of severe valvular heart disease or cardiomyopathy;
- History of stroke or clinical evidence of thrombus formation;
- Severe heart failure (NYHA III-IV class);
- High-risk cardiac conditions (e.g., acute myocardial infarction, coronary artery disease); In the above different types of rapid arrhythmias, the inclusion criteria primarily focus on the diagnosis and control of clinical symptoms for different types of arrhythmias, while the exclusion criteria focus on avoiding patients with severe comorbidities or those unable to tolerate surgery. Through this patient screening method, the safety of the study and the accuracy of the data are ensured, thereby enabling a better assessment of the clinical efficacy of the new EasyStars catheter.
Criteria the registry did not label
