Does anyone have any tips for interpreting which abnormal rhythm I'm looking at?
Before you look at the ECG, look at the clinical picture to get an idea of what you might be looking for.
Start with the basics... Rate (fast or slow) and Rhythm (regular v irregular)
Then look at intervals... PR, QRS, QT, ST
Then focus on QRS... wide or narrow
Then look closely at ST in each lead for elevation or depression
Then look at morphologies... (peaked T waves, notched QRS, etc)
Also, any good tips for determing if ST elevation is present?
Use a straight edge along the PQ segment and look closely at the ST voltage.
Post some strips, along with your interpretations, and you'll probably get some good feedback.
