In this lecture Professor Zach Murphy will present on arrhythmias! We will start by covering the basics with the differences between tachyarrhythmias, bradyarrhythmias, conduction blocks, and a short discussion on sick-sinus syndrome.

We will then move into the pathophysiology and underlying causes for these arrhythmias. These will include changes in automaticity of the heart, triggered activity, and re-entrant circuits. In conclusion, we will be discussing all of the ECG differences between these types of arrhythmias and how to treat these conditions!
