Which of the following should appear on an EKG tracing if a patient's arm moved during recording?
Alternating current (AC) interference
Arrhythmia
Somatic tremor
Interrupted baseline
The Correct Answer is C
A. Alternating current (AC) interference: AC interference is caused by electrical equipment near the EKG machine and appears as uniform, small, rapid spikes. It is not caused by patient movement.
B. Arrhythmia: An arrhythmia refers to an abnormal heart rhythm and is related to cardiac function, not patient movement.
C. Somatic tremor: Somatic tremor is caused by voluntary or involuntary muscle movement, such as a patient moving their arm, which creates artifact on the EKG tracing that appears as irregular, erratic spikes.
D. Interrupted baseline: An interrupted baseline occurs when the electrical connection is lost, often due to a lead falling off, not due to patient movement.
