Retired US Navy Veteran

“I felt light-headed, got sweats really bad, felt my heart pounding… next thing I knew I was in an ambulance. I was scared, I was nervous, I didn’t know what was going on. That was an eye-opener—to be somewhere and not know how you got there.”

“I woke up in the morning feeling really sick… My heart started beating really fast… it just felt like I was dying…. So I went and laid down and tried to meditate to get my heart rate back down, and when that wasn’t working I asked my husband to take me to the emergency room.”

“I was on a flight, and all of the sudden I just felt really weird. My heart was racing. I got scared and nervous, and asked the flight attendant if there was a doctor on board… and when I landed I called my doctor and he told me to go straight to the emergency room, right away.”

AFib Treatment Options

How is AFib treated?

Everyone’s AFib experience is unique.

AFib Treatment with Medication Icon


Most people with AFib are first put on medications to restore their heart rhythm, manage the symptoms of AFib, and minimize their risk of stroke. Medications may cause unwanted side effects and may not work for everyone.

~50% of patients do not respond to or cannot tolerate medications.1

AFib Treatment with Cardioversion Icon


Cardioversion is a controlled low-dose electric shock your doctor delivers to your heart to restore its natural rhythm. Your electrophysiologist may suggest this as an additional treatment to combine with your medications. Cardioversion is usually not a permanent fix.
