When performing a resting 12-lead EKG, what should the paper speed be set to by default?
Answer: 25 mm/sec
The standard paper speed for a resting 12-lead EKG is 25 mm/sec, which allows proper measurement of intervals and waveform durations.
An EKG technician obtains a tracing showing a regular narrow-complex tachycardia at 150 bpm with sawtooth-shaped waves. What is the most likely rhythm?
Answer: Atrial flutter with 2:1 block
A regular narrow-complex tachycardia at exactly 150 bpm with sawtooth baseline waves is the classic presentation of atrial flutter with 2:1 conduction.
Which artifact appears as a regular, rapid, small-amplitude interference pattern on an EKG tracing?
Answer: 60-cycle (AC) interference
60-cycle or AC interference creates a uniform, fine, rapid oscillation pattern caused by electrical current from nearby power sources.
ST segment elevation in leads V1 through V4 most likely indicates ischemia in which coronary artery territory?
Answer: Left anterior descending artery
Leads V1-V4 correspond to the anterior wall of the heart, which is supplied by the left anterior descending artery.
What is the correct limb lead placement for the right arm electrode?
Answer: Anywhere on the right arm between shoulder and wrist, avoiding bony prominences
The right arm electrode can be placed anywhere on the right arm between the shoulder and wrist, as long as bony prominences and areas of excessive movement are avoided.
What does the T wave on an EKG tracing represent?
Answer: Ventricular repolarization
The T wave represents ventricular repolarization, which is the recovery phase of the ventricles after contraction.
