Rule The Arrhythmia Dr Peter Kas

In Rule the Arrhythmia A/Prof Peter Kas takes us into a simplified mnemonic to work out the arrhythmias. The reality is that ECG’s are the right rate, slow or fast.

• If they are slow then its a sinus, junctional or Mobitz block or complete heart block and we need to speed them up if they are symptomatic or if there is a significant potential to deteriorate.
• If they are fast we ask 3 questions:

1. Is it narrow? its sinus and SVT or atrial fibrillation(if irregularly irregular)

2. Is it wide? If yes and has a rate greater than 120bpm then its VT- Cardiovert.
