hyperkalemia =

this is an example of _____, characterized by sine wave pattern

hyperkalemia

this shows T wave peaking in _______

- calculate HR

- check intervals (PR, QTc, QRS width)

- check axis (normal, left, right)

- rhythm (ask these questions if not obvious): P wave before every QRS (& are they upright in I, II, AVR?), is QRS wide or narrow, is it regular or irregular

- blocks?

- check for evidence of infarct, injury, ischemia (ST segments, T waves, pathologic Q waves); remember LBBB, pacemaker, and WPW obscure findings

- check for chamber enlargement

- overall impression?
