Summary

Calculate rate and regularity, measure intervals, recognize waveform/rhythm families, identify pacemaker/ST-T abnormalities, and escalate life-threatening findings using the patient's status—not the monitor alone.

Key Points

Common Mistakes

  • Regularity judged from 'QRS interval' instead of R-R.

Exam Tips

  • Measure first, label second.
