basic dysrhythmias exam 2 Questions
and Answers (2024)
what do you do if artifacts occur on an ECG? - Correct Answer
✅check connections in equipment
rhythm starts in the SA node, 60-100 BPM, normal conduction
pathway - Correct Answer ✅normal sinus rhythm
normal P wave length - Correct Answer ✅.06-.20
the time of passive of impulse through the atria, causing
atrial depolarization (atrial contraction) - Correct Answer ✅P
wave
normal PR interval length - Correct Answer ✅.12-.20
time taken for the impulse the spread through the atria, AV
node, and bundle of HIS, bundle branches, & purkinje fibers,
right up until ventricular contraction.
(atrial contraction -> beginning of ventricular contraction) -
Correct Answer ✅PR interval

normal QRS length - Correct Answer ✅<.12
time taken for depolarization of both ventricles
(systole- ventricular contraction) - Correct Answer ✅QRS
normal ST segment length - Correct Answer ✅.12
time between ventricular depolarization and repolarization;
should be isoelectric.
