1 Big Box - 0.20 sec
1 Small Box - 0.04 sec
1st Degree AV Block - Regular
Rate: 60-100
P Wave: Present, upright
PR interval: >0.20 sec CONSISTENTLY LONG
QRS: <0.12 sec
Husband stays late till 9 consistently
2nd Degree AV Block Type I Mobitz, Wenckebach - IRREGULAR
Rate: 60-100
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
2nd Degree AV Block Type II - Irregular or regular
Rate: <60
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
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
