Heart rhythm treatment options

OHSU's heart rhythm experts work as a team to treat every kind of arrhythmia, palpitation and flutter including AFib (atrial fibrillation), tachycardia, complete heart block and Long QT Syndrome. Treatment options can include:

  • Ablation (radiofrequency and epicardial) — a less invasive treatment that sends radiofrequency signals via a catheter to your heart to prevent the abnormal signals that cause arrhythmia.
  • Pacemaker — a common solution to regulate an irregular heartbeat caused by a heart attack, age, or other factors.
  • Defibrillator — if your heartbeat is irregular and abnormally fast, a defibrillator may be required to deliver a shock to the heart to slow the heartbeat to a normal rhythm.
  • Miniature heart monitor — a tiny monitor implanted under the skin to help detect potentially fatal heart muscle misfires before they become deadly
  • Laser lead extraction — technically challenging procedure to remove wires when a permanent pacemaker or implantable cardiac defibrillator (ICD) is removed or replaced.
  • Ventricular arrhythmia care — our first-of-its-kind program combines expert arrhythmia care with treatment for anxiety, depression and related symptoms.

Patient story: Craig

Knight Cardiovascular Institute patient Craig

I live in Texas, and after 64 years of almost perfect health, experiencing a cardiac arrest was the last thing on my mind. I had started a new health routine 18 months prior that involved exercise and health supplements. Immediately I developed night sweats, something I had never experienced before.
