A-Paced Patterns (Single-Chamber Atrial) — ECG Academy Lesson

Recognize atrial-paced patterns, confirm atrial capture, and separate expected A-paced behavior from concerning changes.

Learning Objectives

• Identify A-paced spike-before-P-wave patterns
• Differentiate A-paced strips from sinus rhythm and artifact
• Recognize mixed native and A-paced transitions as expected demand behavior
• Escalate when capture becomes inconsistent or pattern changes from baseline
