EKG第 76 / 100 题
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
解析
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.

- A monitored patient has a regular rhythm with a rate of 76, a P wave before each QRS, and normal intervals. This rhythm is best described as:
- A cardiac monitor shows a regular rhythm with a P wave before each QRS at a rate of 48 beats per minute. This is best described as:
- A monitored patient's rhythm is regular with a normal-appearing complex and P waves, at a rate of 120 beats per minute. This is best described as:
- An EKG shows a baseline that gradually drifts up and down across the tracing. This wandering baseline is most often caused by:
- A tracing shows a uniform, thick, fuzzy line with small regular spikes about 60 times per second. This artifact is most consistent with:
- An EKG shows an irregularly irregular rhythm with no clearly identifiable P waves. This is most consistent with:
