Medscape ECG quiz

These are mainly rhythm and conduction disturbances. I have a minor quibble with case 1. It is not classic Mobitz II AV block. The level of block here is probably in the common bundle of His. The prognosis and appropriate treatment are less well understood than that of classic Mobitz II, in which the lesion is in the bilateral bundle branches. Pattern recognition will not help you here. You must know basic electrophysiology and bring it to the bedside.
