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
asystole - ansabsence of contractions of the heart
Atrial Fibrillation (A-Fib) - ansan irregular and often very fast heart rate originating from abnormal conduction in the atria
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
Junctional Rhythm - ans40-60 Regular! -impulse from AV node w/ retro/antegrade transmission
Junctional Tachycardia - ans>60 bpm (ms. K; 150-250)
monomorphic ventricular tachycardia - anspresents with wide QRS complexes of a common shape.
normal sinus rhythm - ansheart rhythm originating in the sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute
Premature Atrial Contraction (PAC) - ansHeart Rate: Depends on underlying rhythm Regularity: Interrupts the regularity of underlying rhythm P-Wave: can be flattened, notched, or unusual. May be hidden within the T wave PRI: measures between .12-.20 seconds and can be prolonged; can be different from other complexes QRS: <.12 seconds
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
Sinus Arrhythmia - ansAppearance is ALMOST NORMAL: Respiratory - Circulatory interaction Rate INCREASES with INSPIRATION (IN=IN)
Sinus Bradycardia - ans< normal sinus rhythm
Sinus Tachycardia - ans>100 (100-150)
