Atrial flutter

Flutter atriorum · Flutter síní

What it is

One electrical circuit racing round the right atrium about 300 times a minute — a cousin of atrial fibrillation, with the same stroke risk, and usually curable by ablation.

Symptoms & signs

  • Fast regular palpitations (often 150 a minute)
  • breathlessness
  • dizziness
  • tiredness
  • sometimes none

🚩 Get help if…

  • call 112 / 911 now Chest pain, fainting or severe breathlessness
  • call 112 / 911 now Sudden weakness of face or limbs, or slurred speech
  • see a doctor soon Heart racing for over an hour
  • see a doctor soon Swollen ankles or breathless lying flat

Where it strikes

Medical treatment

  • ECG
  • rate control (beta blockers)
  • anticoagulation by stroke score
  • cardioversion
  • catheter ablation of the circuit (over 90% success)

Natural & lifestyle

  • Limit alcohol
  • treat sleep apnoea and high blood pressure
  • weight control

Emerging & experimental

  • Pulsed-field ablation
  • wearable ECG screening

Alternative, off-label & anecdotal

Approaches used outside the guidelines, with what their supporters report and what testing has found so far.

  • Magnesium — may help rate control; small studies early / small studies
  • Hawthorn — a traditional heart herb; interacts with heart drugs anecdotal / traditional
  • Yoga — small trials reduce episodes (in atrial fibrillation) early / small studies
