normal sinus rhythm - Answer--heart rhythm originating in the sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute
Sinus Arrhythmia - Answer--Appearance is ALMOST NORMAL: Respiratory - Circulatory interaction Rate INCREASES with INSPIRATION (IN=IN)
Sinus Bradycardia - Answer--< normal sinus rhythm
Sinus Tachycardia - Answer-->100 (100-150) normal sinus rhythm
Premature Atrial Contraction (PAC) - Answer--Heart 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
Sinus Arrest/Pause - Answer--- SA node doesn't fire
Atrial Fibrillation (A-Fib) - Answer--an irregular and often very fast heart rate originating from abnormal conduction in the atria
Atrial Flutter - Answer--irregular beating of the atria; often described as "a-flutter with 2 to 1 block or 3 to 1 block"
Junctional Rhythm - Answer--40-60 Regular! -impulse from AV node w/ retro/antegrade transmission
Junctional Tachycardia - Answer-->60 bpm (ms. K; 150-250)
Ventricular fibrillation (V-fib) - Answer--abnormal heart rhythm which results in quivering of ventricles
Idioventricular Rhythm - Answer--< looks like vtach but slow
Accelerated Idioventricular Rhythm - Answer--Rate: 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 - Answer--absence of contractions of the heart
Failure to capture (pacemaker) - Answer--
failure to sense (pacemaker) - Answer--
Atrial paced rhythm - Answer--spike before P wave
Ventricular paced rhythm - Answer--ventricular contractions which occur in cases of complete heart block.
