Basic EKG Rythms and Arrythmias

QuestionAnswer
AR 60-100; PRi 0.12 or greater Normal Sinus Rhythm
AR < 60; PRi 0.12 or greater Sinus Bradycardia
AR 101 - 150; PRi 0.12 or greater Sinus Tachycardia
No identifiable P waves; R - R regular Atrial Fibrillation
AR 251 - 400; P - P regular; R - R regular or irregular; Saw-toothed baseline Atrial Flutter
AR 151-250; R-R regular or irregular; P-P regular; PRi 0.12 or greater; QRS width normal Atrial Tachycardia
P-P interval irregular; difference between shortest and longest P-P 0.12 or greater; PRi 0.12 or greater Sinus Arrhythmia
Complete absence of P, QRS, and T creating a pause in the rhythm Sinus Block
Every P wave is followed by QRS; PRi > 0.20, PRi is consistent First Degree Heart Block
This rhythm has no P waves, a wide and bizarre QRS, the R-R interval is regular and the ventricular rate is > 100 Ventricular Tachycardia
This rhythm has a wavy baseline, no P waves, and no QRS. Ventricular Fibrillation
This rhythm has no identifiable P waves, R-R interval is regular, a normal QRS, and a ventricular rate > 100 Supraventricular Tachycardia
This rhythm has a flat baseline. End of life rhythm Asystole
This rhythm has wide & bizarre QRS complexes with no associated P waves; R-R is regular and ventricular rate <40 Idioventricular
This rhythm has wide & bizarre QRS complexes with no associated P waves; R-R is regular and ventricular rate of 40-100 Accelerated Ventricular Rhythm
Late QRS that follows a pause in the rythm; P wave can be in front of QRS with PR1 < 0.12, after the QRS in the ST segment or in the QRS (not seen). The QRS in front of the late complex is 0.10 or less. (considered helping beat) Junctional Escape Beat
With this rhythm a P wave can be in front of QRS with PR1 < 0.12, after the QRS in the ST segment or in the QRS (not seen). R-R is regular; the QRS is 0.10 or less; VR is 40-60 Junctional Rhythm
With this rhythm a P wave can be in front of QRS with PR1 < 0.12, after the QRS in the ST segment or in the QRS (not seen). R-R is regular; the QRS is 0.10 or less; VR is 61-100 Accelerated Junctional Rhythm
With this rhythm a P wave can be in front of QRS with PR1 < 0.12, after the QRS in the ST segment or in the QRS (not seen). R-R is regular; the QRS is 0.10 or less; VR is 101 or greater Junctional Tachycardia
P-P regular; R-R regular; PRi varies 3rd Degree (complete) heart block
P-P regular; R-R irregular; PRi gradually lengthens until QRS complex is dropped 2nd Degree Mobitz type I (Wenchebach)
P-P regular; every P does not have a QRS; R-R could be regular or irregular; PRi is 0.20 or less and constant; QRS is greater than 0.10 2nd Degree Mobitz type II (BBB)
Every other P followed by QRS, P-P regular, R-R regular, PRi constant; Atrial rate 2x Ventricular rate 2nd Degree heart block with 2:1 conduction
Early P wave; may or may not have QRS (if QRS PRi 0.12 or greater). Incomplete or non compensatory pause PAC
Early QRS with or without P wave; P wave can be in front of QRS with PR1 < 0.12, after the QRS in the ST segment or in the QRS (not seen); the QRS is 0.10 or less; PJC
early, bizarre QRS with no associated P wave; QRS > 0.10; complete compensatory pause PVC
