Heart rhythms.

These are the rhythms you should be able to recognize before the next test.
You should also be able to define the arrhythmia.

Ventricular tachycardia (Vtach)
Ventricular Fibrillation (Vfib)
Atrial fibrillation (Afib)
Atrial flutter
NSR (normal sinus rhythm)
Sinus bradycardia
Sinus tachycardia

I changed my mind we will do these next semester:
Paroxysmal supraventricular tachycardia (PSVT)
1st heart degree block
Both second degree blocks
