Question | Answer |
---|---|
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 |
