or the time recovery before another contraction
turn up to 2 correct answerswhat can you do with the sensitivity dial if the ECG tracing is too
small
aVL, aVR, aVF correct answersthe augmented leads are known as
muscle voltage artifacts correct answerspatients with various neurological disorders can produce
this on an ECG tracing
pacemaker arrhythmias correct answersshows up as vertical signals that represent the electrical
activity
