Heart Rhythm Clinic Overview


Watch Mayo Clinic cardiologists and others discuss many conditions and treatments related to cardiovascular diseases and cardiovascular surgery.

The staff in the Heart Rhythm Clinic at Mayo Clinic has experience and expertise diagnosing and treating adults and children with all types of heart rhythm disorders (arrhythmia). The Heart Rhythm Clinic offers advanced diagnostic procedures and treatments for arrhythmias.

The Heart Rhythm Clinic takes a patient-centered, team approach. Doctors specializing in heart disease (cardiologists) who are trained in evaluating and treating heart rhythm problems and their complications work with other specialists to provide comprehensive care.

Disorders evaluated in the Heart Rhythm Clinic include:

  • Fainting (syncope). If you have experienced syncope, doctors may assess the severity of your condition and conduct further tests to determine if medicine or placement of a pacemaker or implantable cardioverter-defibrillator (ICD) would be beneficial for you.
  • Heart failure. If you have heart failure, doctors may evaluate you and determine whether you're a candidate for a biventricular pacemaker.
  • Sudden cardiac death. If you have heart disease, doctors may assess your risk of sudden cardiac death and determine whether you're a candidate for an ICD.
  • Heart rhythm disorders (arrhythmias). If you have heart rhythm disorders (arrhythmias), doctors may assess whether medical (drug) therapy, cardiac ablation, a pacemaker, ICD or other advanced treatment options may be appropriate treatments for your condition.

Conditions treated in the Heart Rhythm Clinic include:

The experienced staff uses advanced imaging and mapping techniques. These diagnostic tools allow doctors to develop a treatment plan tailored to you. Your treatment might involve a visit to an electrophysiology laboratory.

Staff will follow up with you after your treatment. If you had a pacemaker implanted, staff will educate you about your pacemaker and modify its functions to meet your needs.

Doctors trained in pediatric cardiology (pediatric cardiologists) treat children with heart rhythm disorders at Mayo Clinic in Rochester, Minnesota.

State-of-the-art implementation of artificial intelligence

Mayo Clinic is a leader in bringing artificial intelligence (AI) cardiology tools and technology into clinical practice to help people who have or are at increased risk of heart rhythm disorders. The clinic's AI cardiovascular team is applying these new techniques to early risk prediction and diagnosis of serious and complex heart rhythm problems. For example, AI-guided ECGs are detecting atrial fibrillation before any symptoms are evident.

Innovative research

The physician-scientists of the Heart Rhythm Clinic research new treatments and improve the care of people with heart rhythm disorders. Read more about research in the Cardiovascular Research Center.
