Proactively Managing Heart Rhythm Problems, From Atrial Fibrillation to Sudden Cardiac Death

The combination of population data and AI tools is transforming the future of cardiology, allowing physicians to predict the nature of heart rhythm problems so they can devise effective prevention strategies. Once arrhythmias manifest, the Smidt Heart Institute offers the full range of treatment options, from ablation to experimental regenerative approaches.

  • Embrace new developments in the field, including smart detection of AFib and ventricular arrythmias as well as AI analysis that predicts arrhythmia events
  • Improve prediction capabilities for sudden cardiac arrest beyond the status quo via investigator-initiated studies
  • Lead research that changes conventional wisdom about common heart rhythm conditions


  • Unite clinical expertise and scientific research in the Center for Cardiac Arrest Prevention
  • Employ cutting-edge 3D mapping and catheter ablation technology for treatment of atrial and ventricular arrhythmias
  • Implant leadless pacemakers and stroke-prevention devices
  • Treat even the rarest and most complex arrhythmias with genetic testing and tailored management as appropriate

Eliminating the Unknowns in Cardiology

Contrary to conventional wisdom on AFib, women—when height is accounted for—have a 50% higher risk of developing the abnormal heart rhythm disturbance than men, suggesting AFib prevention and intervention should be emphasized in patients of both sexes. JAMA Cardiol; PMID: 36044209

"I was scared, but the way my doctor explained the procedure made me feel very comfortable, very secure. He was confident, and that made me feel like, OK, I can trust you."

Paroxysmal AFib/flutter patient
Maywood, California

the case

Claudia Huerta (44) experienced high resting heart rates, fatigue and dizziness, which prompted her to schedule a visit with her primary care physician. Follow-up monitoring with Cedars-Sinai resulted in a diagnosis of hereditary paroxysmal atrial fibrillation (AFib)/flutter (13% burden).

the care

Recommended treatment included lifestyle modification with regular exercise, weight loss and elimination of alcohol. Claudia committed to a rigorous exercise and dietary program and elected to undergo AFib/flutter catheter ablation rather than taking pills for the rest of her life. The ablation was completed in November 2021 with no complications.

the conclusion

Claudia maintained her lifestyle modifications and has lost 80 pounds since diagnosis. She competes in high-level bodybuilding competitions without the use of supplements. She has been free of AFib since the ablation, is off all cardiac medications and will continue with annual monitoring.
