Whether its Fast AF or as Simon would prefer... Atrial Fibrillation with a Rapid Ventricular Response (RVR), this is a condition that any paramedic or emergency clinician worth their salt should be…
And we should probably start by looking at exactly what atrial fibrillation is.
Let's start with the absolute basics.
As you said in the intro, Josh, AF is the most common sustained heart rhythm disturbance that we see in clinical practice.
And the European Society of Cardiology estimate that there's a UK prevalence of 2% to 4% of adults.
In AF, instead of the atria, which are the two upper chambers of the heart, contracting in a coordinated way, they are activated by rapid chaotic electrical impulses originating from all over the atria.
So rather than squeezing blood efficiently into the ventricles, they simply quiver or fibrillate.
Ooh.
No, I needed more than that.
Oh.
Sorry, I don't want these
arms all together.
That'll do.
That'll do.
Why are we
doing an R there?
How does that? Fibrillate.
It's atrial fibrillation.
That's the big reveal.
It's the big reveal, Simon.
Okay.
Do you
want to do it again? No, it's fine.
It's fine.
You've got to find ways to zhuzh up this bit, but it's very hard to do that.
It's very dry.
