In the article ECG Impulse Basics we covered normal electrical flow through the heart.
Dysrhythmias are variations to this electrical flow caused by disease states or other physiological abnormalities.
**Side note. Dysrhythmia and Arrhythmia may be used interchangeably at times but these terms are not interchangeable. The prefixes “DYS” and “A” have different meanings. Dys- is a prefix used to denote disease, abnormal, or faulty whereas the prefix a- or an- denotes without or lacking. Therefore, a Dysrhythmia is an abnormal or faulty rhythm and Arrhythmia is without rhythm at all.**
Here we will take a look at the many different dysrhythmias. These will be grouped according to where the dysrhythmia takes place.
Sinus Rhythms
Atrial Dysrhythmias
Heart Blocks
Ventricular Dysrhythmias
Junctional Rhythms
