exam 2- basic dysrhythmias with 100% correct solutions 2024

what do you do if artifacts occur on an ECG? correct answerscheck connections in equipment rhythm starts in the SA node, 60-100 BPM, normal conduction pathway correct answersnormal sinus rhythm normal P wave length correct answers.06-.20 the time of passive of impulse through the atria, causing atrial depolarization (atrial contraction) correct answersP wave normal PR interval length correct answers.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 answersPR interval normal QRS length correct answers<.12 time taken for depolarization of both ventricles (systole- ventricular contraction) correct answersQRS normal ST segment length correct answers.12 time between ventricular depolarization and repolarization; should be isoelectric. (end of systole -> beginning of diastole) correct answersST segment normal T wave length correct answers.16 ventricular relaxation (diastole) correct answersT wave is K or Na higher inside the cell? correct answersK is K or Na higher outside the cell? correct answersNa what happens with depolarization of a cell? correct answersNa influx into cell normal QT correct answers.34-.43 time taken for entire depolarization/repolarization of ventricles (ventricular contraction + relaxation)
