We’ve covered tachycardias, both narrow and broad before, but we need to complete the set, so we’ll be looking this time at the slower end of the spectrum with bradycardias.
Bradycardias can be a physiological state in some physically fit patients, but they could be of more concern in others.
They occur due to a multitude of reasons, some cardiac and some not and they can require no treatment at all right up to those peri-arrest patients where you’ll be cracking open your critical care drugs and starting to pace them externally before getting them to definitive care.
In this episode we take an in-depth look at the cause, electrophysiological pathways, assessment and treatments for bradycardias.
