Definition
A = Paroxysmal Atrial Tachycardia (PAT):
Rhythm – regular
p and t wave merge = fairly big amplitude
Rate – 160-250 bpm
QRS duration - normal
Term

Definition
B = multi-focal PVC’s Rhythm – regular or irregular p-wave – normal (1:1 with QRS rate) Rate – normal QRS duration – normal after p wave (wide for PVC) P-R interval – normal ** odd wave forms either  or ↓ horizontal line. Different pattern based on where the PVC originates **
Term

Definition
C = Normal Sinus Rhythm (NSR): SA node = heart’s normal pacemaker p-wave – visible before each QRS complex Rhythm – regular QRS duration – normal Rate – normal (60-100 bpm) P-R interval – normal (< 5 small squares
Term

Definition
D = 2° heart block Type II or Mobitz II: Rhythm – regular p-wave – 2:1 or 3:1, constant but faster than QRS Rate – normal to slow QRS duration – prolonged or normal P-R interval – normal or prolonged but consistent Multiple p-waves for each QRS, but QRS is caused by a p-wave
Term

Definition
E = Atrial Fibrillation (a-fib): Rhythm – irregularly irregular p-wave – not distinguishable (atria firing) “ectopic foci” – lots of areas firing at the same time Rate – 100-160 bpm QRS duration – normal P-R interval – not measurable
Term

Definition
F = Bigeminy: Rhythm – rhythm p-wave – normal with regular QRS, absent with PVC Rate – normal QRS duration – abnormal complex P-R interval – N/A ** every other beat is a PVC **
Term

Definition
G = 3° heart block: Rhythm – regular p-wave – unrelated, normal but faster than QRS complex Rate – slow QRS duration - prolonged P-R interval – variation ** multiple p-waves for each QRS, but p-wave doesn’t cause QRS. Atria and ventricles each generate their own rhythm**
Term
[image]
Definition
H = Sinus Bradycardia: Rhythm – regular p-wave – visible before each QRS complex Rate – slow < 60 QRS duration – normal P-R interval – normal
Term
[image]
Definition
I = Ventricular Tachycardia (VT): Rhythm – regular p-wave – not seen Rate – 180-190 bpm QRS duration – long P-R interval – N/A ** can lead to cardiac arrest due to poor cardiac output **
Term
[image]
Definition
J = Sinus Pause: Rhythm – regular except at pause p-wave – visible before each QRS complex Rate – 45-100 bpm QRS duration - normal T-P interval – variable distance (rate) ** At least 1 sec pause between end of t-wave and start of p-wave
Term
[image]
Definition
K = Atrial Flutter: Rhythm – regular p-wave – multiple flutters 2-3:1 with QRS Rate – 110-ish QRS duration – normal P-R interval – not measurable
Term
[image]
Definition
L = 1° heart block: Rhythm – regular p-wave – normal (1:1 ratio with QRS) Rate – normal QRS duration – normal P-R interval – prolonged (>5 small squares) ** P-R interval > 0.2 sec
Term
[image]
Definition
M = Sinus Tachycardia: Rhythm – regular p-wave – normal (1:1 ratio with QRS) Rate – fast > 100-110 bpm QRS duration – normal P-R interval – normal
Term
[image]
Definition
N = Ventricular Fibrillation (v-fib): Rhythm – irregular p-wave – not recognizable Rate – 300+ and disorganized QRS duration – not seen P-R interval – N/A ** this pt needs to be defibrillated QUICKLY **
Term
[image]
Definition
O = Trigeminy: Rhythm – rhythm p-wave – normal with regular QRS, absent with PVC Rate – normal QRS duration – abnormal complex P-R interval – N/A ** every THIRD beat is a PVC **
Term
[image]
Definition
P: 2° heart block Type I or Mobitz I: (Wenckebach) Rhythm – regularly irregular p-wave – 1:1 x3-ish  1:0 Rate – normal to slow QRS duration – normal P-R interval – progressively lengthened until QRS complex is dropped
Term
[image]
Definition
Q = Junctional Rhythm: Rhythm – regular p-wave – absent - SA not firing, coming from AV node Rate – 40-60 bpm QRS duration – normal P-R interval – variable
Term

Definition
R = Unifocal Premature Ventricular Contraction (PVC): Rhythm – regular or irregular p-wave – normal (1:1 with QRS rate) Rate – normal QRS duration – normal after p wave (wide for PVC) P-R interval – normal ** odd wave forms either  or ↓ horizontal line. Same pattern each time **
