2nd Degree Heart Block (Mobitz II) - ansRare, but more serious Sudden appearance of a nonconducted P-wave P-waves are nl, but some aren't followed by a QRS complex PR & RR intervals are constant 2nd degree heart block type 1 (Wenkebach) - ansProgressively longer PR interval until the P wave is not followed by a QPR 3rd degree heart block - ansno obvious correlation between p and qrs, need pace maker Accelerated Idioventricular Rhythm - ansRate: 50 - 100 usually (usually slow) P wave: Obscured by ventricular waves (occur during ventricular contraction) - SA node slower than faster ventricular pacing than should be QRS: Wide QRS Conduction: Ventricular only Rhythm: Regular
Atrial Flutter - ansirregular beating of the atria; often described as "a-flutter with 2 to 1 block or 3 to 1 block" Atrial paced rhythm - ansspike before P wave Bigeminy PVC - ansevery other beat is a PVC Failure to capture (pacemaker) - ans failure to sense (pacemaker) - ans First degree heart block - ansatrioventricular (AV) block in which the atrial electrical impulses are delayed by a fraction of a second before being conducted to the ventricles Idioventricular Rhythm - ans< looks like vtach but slow
Premature Junctional Contraction - ansInverted p wave or hidden p wave PRI<0.12 or none Normal QRS premature ventricular contraction (PVC) - ansa ventricular contraction preceding the normal impulse initiated by the SA node (pacemaker) PVC couplets - ansPVC occurring in pairs, no adequate C.O. when this occurs Sinus Arrest/Pause - ans- SA node doesn't fire
Junctional Tachycardia - ans>60 bpm (ms. K; 150 - 250)
P wave: Obscured by ventricular waves QRS: Wide QRS - "Twisting of the Points" Conduction: Ventricular only Rhythm: Slightly irregular Ventricular fibrillation (V-fib) - ansabnormal heart rhythm which results in quivering of ventricles Ventricular paced rhythm - ansventricular contractions which occur in cases of complete heart block. 2nd Degree Heart Block (Mobitz II) - ansRare, but more serious Sudden appearance of a nonconducted P-wave P-waves are nl, but some aren't followed by a QRS complex PR & RR intervals are constant 2nd degree heart block type 1 (Wenkebach) - ansProgressively longer PR interval until the P wave is not followed by a QPR 3rd degree heart block - ansno obvious correlation between p and qrs, need pace maker Accelerated Idioventricular Rhythm - ansRate: 50 - 100 usually (usually slow) P wave: Obscured by ventricular waves (occur during ventricular contraction) - SA node slower than faster ventricular pacing than should be QRS: Wide QRS Conduction: Ventricular only Rhythm: Regular
