Which of the following artifacts may occur if a patient is talking during an EKG?
Alternating current
Interrupted baseline
Somatic tremor
Wandering baseline
The Correct Answer is C
A. Alternating current: Alternating current interference is due to electrical equipment, not patient movement or talking.
B. Interrupted baseline: An interrupted baseline occurs when there is a break in the electrical connection, often due to a loose lead, not because of patient talking.
C. Somatic tremor: Somatic tremor can occur due to muscle movement, including that caused by talking. This can result in erratic, uneven spikes on the EKG tracing.
D. Wandering baseline: A wandering baseline is usually caused by improper electrode placement or poor skin contact, not talking. However, excessive movement, including deep breaths or large chest movements during talking, can contribute to a wandering baseline.
