Multiple rhythms

When there are multiple rhythms in one ECG this can either be from a change in rhythm or the presence of two competing rhythms at once. Two competing rhythms are also known as Parasystole.

What is the Rhythm?

This ECG is from a young man who presented shortly after a 45 min episode of palpitations, shortness of breath, chest pressure and presyncope. He was an athlete.

This ECG shows marked sinus bradycardia with AV dissociation by default (not AV block) with junctional escape beats.
