Sinus Bradycardia Regular Rate: < P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec 3. Sinus Tachycardia Regular Rate: 100- P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec
4. Premature Atrial Contraction IRREGULAR Rate: depends on underlying rhythm P wave: Present or hidden in T wave PR Interval: 0.12-0.20 sec QRS: <0.12 sec 5. Atrial Fibrillation IRREGULAR Atrial rate: UNMEASURABLE Ventricular rate: variable P wave: unable to see PR Interval: N/A QRS: <0.12 sec 6. A fib RVR IRREGULAR Ventricular rate: 100- P wave: unable to see

18.2nd Degree AV Block Type I Mobitz, Wenckebach IRREGULAR Rate: 60- P wave: Present, upright PR Interval: Progressively longer until drop (PR interval longer and longer until drop) QRS: <0.12 sec Husband stays late till 9, then 11, then 1, then doesn't come home at all 19.2nd Degree AV Block Type II Irregular or regular Rate: < P wave: Present, upright PR Interval: PR interval consistently LONGER like type 1 but then a QRS will drop QRS: <0.12 sec Husband stays late till 9 consistently, then wife goes out and doesn't come home 20.3rd Degree AV Block Atrials and ventricles don't communicate Rate: regular atrial
P wave: Present, upright No relationship between P waves and QRS PR Interval: VARIABLE QRS: variable P-P ad R-R consistent but NO correlation Husband and wife live separate lives and don't communicate 21.SA Node 1st 60- 22.AV Node 2nd 40- 23.Bundle of His 3rd 40- 24.Right and Left Bundle Branches 4th 40- 25.Purkinje Fibers 5th 20-
