Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken explore the ideas shaping our health and wellbeing.

In this episode, they turn their attention to heart palpitations. That sudden flutter, skipped beat or racing heart can feel alarming, but what’s actually going on, and when should you be concerned?

They break down what palpitations are, what causes them, and what’s happening in the heart when you feel them. From everyday triggers like stress and caffeine to more serious rhythm problems, they explore the full spectrum, from completely normal to potentially dangerous.

They also look at how doctors investigate palpitations, the warning signs not to ignore, and what to do if you’re worried.

To help them unpack it all, they’re joined by Dr Pranev Sharma, Consultant Cardiologist at Midland Metropolitan Hospital in Birmingham.
