Ventricular tachycardia		Narrow QRS complex, P waves absent or inverted, rate 60-100
Ventricular fibrillation		Heart rate increases with inspiration and decreaseswith expiration
Atrial fibrillation		Heart rate 40-60, P waves absent or inverted, QRS narrow
Third degree block		A premature wide and bizarrely shaped QRS complex
Idioventricular		Hallmark sign of this rhythm is saw tooth waves
Asystole		Atria and ventricles do not communicate and initiate impulses separately
Sinus tachycardia		PR interval lengthens each cycle until a QRS complex is dropped
Wenckebach		Chaotic unorganized lethal rhythm originating n the ventricles
WAP		Slightly irregular rhythm, three different P waves in six seconds, rate 60-100
Atrial flutter		Three or more ventricular escape beats in a row at a rate of 20-40
First-degree heart block		Premature beat with an absent or inverted P wave
Torsades de pointe		This supraventricular rhythm is irregularly irregular
Sinus arrhythmia		Heart rate increases with pain, fever, hypovolemia
Junctional escape		Life threatening wide complex tachycardia
PJC		Rhythm occurs in well-conditioned athletes
Sinus bradycardia		Tachycardia originating in the ventricles that twists along the baseline
PVC		Absence of all electrical activity
Accelerated junctional		Consistent prolonged PR intervals across an entire strip
