What is indicated by a pacer spike on an EKG strip?

• A. An intrinsic heart beat
• B. A heart block
• C. A pacing stimulus entering the heart
• D. Electrode disconnection

Answer: (C)

A pacer spike on an EKG strip indicates a pacing stimulus entering the heart. This spike appears as a vertical line on the EKG, signaling that an artificial pacemaker is delivering an electrical impulse to stimulate the heart's contraction. The presence of a pacer spike means that the pacemaker is functioning properly and is effectively informing the heart to contract, which is essential for patients whose natural heart rhythm is inadequate or absent. Understanding this concept is critical for interpreting EKGs, especially in patients with known pacing devices or those at risk for arrhythmias. The ability to recognize and correctly interpret pacer spikes assists healthcare professionals in providing appropriate cardiac care and assessing the pacer's effectiveness.
