Show notes: Hyperkalaemia can kill before the ECG changes. Learn how level, trend and cause define urgency — not reassurance.
Episode 7 — Hyperkalaemia on the Ward · When to Panic
Not all hyperkalaemia carries the same risk — and the worst delays happen when clinicians look for reassurance in the wrong place.
In this episode, we break down hyperkalaemia risk using a ward-based scenario: high potassium, repeat pending, patient “stable”, and a normal-looking ECG. We focus on what actually predicts danger: level, trend, and cause — and why a normal ECG is not a safety certificate.
You’ll learn:
Why ECG changes aren’t guaranteed and shouldn’t be your gatekeeper
How level, trend, and cause determine urgency
Pseudohyperkalaemia vs true hyperkalaemia (and the danger of guessing)
The most common traps: waiting for repeat bloods, trusting the ECG too much
A senior mindset: protect the heart, then fix the potassium problem
