Pacemaker Spikes, Capture, and Artifact — ECG Academy Lesson

Identify true pacemaker spikes, confirm capture, and separate paced activity from artifact before escalation.

Learning Objectives

• Recognize atrial and ventricular spike placement on strips
• Verify capture by checking immediate post-spike response
• Distinguish artifact from true paced activity using pattern checks
• Communicate objective spike/capture findings for rapid team response
