Basic Dysrhythmia-Relias Study Guide Graded A+

Atrial Fibrillation (A-Fib) {Ans: an irregular and often very fast heart rate originating from abnormal conduction in the atria}Ventricular paced rhythm {Ans: ventricular contractions which occur in cases of complete heart block.}Accelerated Idioventricular Rhythm {Ans: 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 - benign rhythm that is sometimes seen during acute MI or early after reperfusion. - Rarely sustained, does not progress to vfib, rarely requires treatment}Sinus Tachycardia {Ans: >100 (100-150) normal sinus rhythm}Atrial paced rhythm {Ans: spike before P wave}Supraventricular Tachycardia (SVT) {Ans: an abnormal heart rhythm arising from aberrant electrical activity in the heart; originates at or above the AV node}
