How do you determine whether
the atrial rhythm on an ECG
tracing is regular or irregular?
10. Which ECG leads use two leads I, II, and III
distinct electrodes, one of
which is positive and the other
negative?
expiration
11. In sinus arrhythmia, a
gradual de- creasing of the
heart rate is usually associated
with? sinus bradycardia
12. An ECG rhythm strip shows a
ven- tricular rate of 46 bpm, a
regular rhythm, a PR interval of
0.14 sec- ond, a QRS duration
of 0.06 second, and one upright
