EKGPregunta 76 de 100
An EKG tracing shows fuzzy, erratic spikes in the baseline caused by the patient shivering. What is the most likely cause of this artifact?
a.A loose electrode
b.60-cycle electrical interference
c.Wandering baseline from breathing
d.Somatic (muscle) tremor artifact
Explicación
Somatic tremor artifact is caused by muscle movement such as shivering, tremors, or tension, producing fuzzy, erratic spikes on the tracing. Warming the patient and helping them relax can reduce it. Distinguishing artifact from true rhythm prevents misinterpretation.
