What the trials found For clinicians

Arrhythmias: what the trials found

Clinical evidence regarding the management of arrhythmias includes various pharmacological and procedural interventions. The use of Atropine has been evaluated in clinical settings 1, while Atorvastatin was also investigated as a treatment modality 22.

Catheter-based interventions show significant results for specific arrhythmias. The THERMOCOOL® SMARTTOUCH™ Catheter demonstrated that 70.2% of subjects were free from documented symptomatic atrial fibrillation (AF), atrial tachycardia (AT), or atrial flutter (AFL) at a 12-month follow-up (p<0.0001) 5. Additionally, the NAVISTAR THERMOCOOL Catheter showed high rates of acute success (94% to 100%) and significant chronic success for treating symptomatic paroxysmal atrial fibrillation (66% vs 16%, p<0.001) 6.

Other interventions included Colchicine 4 and fat tissue needle aspiration 3.

Recent results — preliminary, needs further review

  • Cardiac Stimulator 8
  • Carelink System 9
  • Perclose ProGlide SMC/ProStyle SMCR Systems 10
  • 123I-metaiodobenzylguanidine (MIBG) evaluation of myocardial scar and uptake 11

For the clinician treating this condition

  • The THERMOCOOL® SMARTTOUCH™ Catheter and NAVISTAR THERMOCOOL Catheter are associated with high rates of acute success and significant reduction in symptomatic atrial arrhythmias over 12 months.
  • Atropine, Atorvastatin, and Colchicine are established interventions within the clinical literature for arrhythmia management.

Questions about Arrhythmias

Can ginsenoside CK help protect my heart from arrhythmias?

Research suggests ginsenoside CK has antiarrhythmic potential and can protect the heart from injury in models of ischemia, sepsis, and chemotherapy, though clinical use is still being studied.
