What does interference from electrical equipment show as on an EKG?

The presence of interference from electrical equipment on an EKG typically manifests as small spikes or artifacts on the tracing. This interference can stem from a variety of sources such as nearby machinery, faulty wiring, or improperly grounded equipment. These small spikes appear alongside the normal waves of the EKG, making it difficult to interpret the patient's heart activity accurately.

Understanding this phenomenon is crucial for medical professionals because it helps them distinguish between true cardiac events and artifacts caused by external electrical interference. By recognizing these small spikes, clinicians can take appropriate measures to minimize interference, ensuring a clear and reliable EKG recording that accurately represents the patient's cardiac function.
