Atrioventricular (ECG AV) blocks made easy! #meded #medsm

p wave = wife

qrs complex = husband

pacer = counseling

Normal sinus rhythm:

The wife (p wave) waits at home for the husband (qrs complex). The husband (qrs) come homes on time every night.

First degree AV block:

The wife (p wave) is waiting at home. The husband (qrs) comes home late every night, but he always comes home and it’s at the same time every night.

Second degree AV block, Type I (Wenckebach periodicity):

The wife (p wave) is waiting at home. The husband (qrs) comes home later and later every night until one night he doesn’t come home at all.

Note: The husband (qrs) must come home at least 2 nights in a row to see this pattern.

Second degree AV block, Type II:

The wife (p wave) is waiting at home. Sometimes the husband (qrs) comes home, sometimes he doesn’t. When he does come home, it’s always at the same time.

Note: This is usually more serious than Type I (Wenckebach) and will sometimes require counseling (pacing).

Third degree AV block:

The wife (p wave) is no longer waiting at home. She and her husband (qrs) are now both on separate schedules and have no relationship and they are no longer talking. Each spouse has a regular, individual schedule.

Note: This frequently requires counseling in the form of a temporary or permanent pacer.
