BASIC DYSRHYTHMIA-RELIAS TEST EXAM WITH VERIFIED AND CORRECT ANSWERS

normal sinus rhythm - CORRECT ANSWER-heart rhythm originating in the sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute Sinus Arrhythmia - CORRECT ANSWER-Appearance is ALMOST NORMAL: Respiratory - Circulatory interaction Rate INCREASES with INSPIRATION (IN=IN) Sinus Bradycardia - CORRECT ANSWER-<60 normal sinus rhythm Sinus Tachycardia - CORRECT ANSWER->100 (100-150) normal sinus rhythm Premature Atrial Contraction (PAC) - CORRECT 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 - CORRECT ANSWER-- SA node doesn't fire - notice absence of P-wave for a complete cycle (a missed cycle) length of pause ≠ multiple of normal rate (block) Atrial Fibrillation (A-Fib) - CORRECT ANSWER-an irregular and often very fast heart rate originating from abnormal conduction in the atria Atrial Flutter - CORRECT ANSWER-irregular beating of the atria; often described as "aflutter with 2 to 1 block or 3 to 1 block" Junctional Rhythm - CORRECT ANSWER-40-60 Regular! -impulse from AV node w/ retro/antegrade transmission - P wave often inverted/buried/follow QRS - slow rate - narrow QRS (not wide like ventricular) Junctional Tachycardia - CORRECT ANSWER->60 bpm (m
