Ekg strips sinus rhythm - Study guides, Class notes & Summaries

EKG EXAM 2 QUESTIONS & ANSWERS 2024 Know what the term 'sinus' indicates about an EKG rhythm - ANSWER-That it is occurring from the SA node Be able to determine all of these things on EKG strips for normal sinus rhythm - ANSWER-Rhythm is regular = same distance between all R waves 1:1 P to QRS ratio HR 60-99 bpm Normal PR intervals and QRS complexes (positive in lead II, negative in aVR) Normal axis deviation is indicated Patient should be asymptomatic Sinus Bradycard...

P wave: PR interval: QRS complex: (ST segment) T wave: QT interval: correct answers • P wave - atrial depolarization and contraction • PR interval - time of travel from the SA node to AV node (.12-.2) • QRS - ventricular depolarization and contraction (.08-.12) - Note: Atrial repolarization occurs during this time, but cannot be seen on EKG • T wave - ventricular repolarization • QT interval - start of ventricular contraction to end of relaxation Systematic Approach to ana...

Dysrhythmias (Including EKG Strips) Latest 2023 Graded A+ Normal Sinus Rhythm Refers to a rhythm that originates in the SA node @ a rate of 60-100 BPM and follows normal conduction pattern of the cardiac cycle. Sinus Bradycardia The conduction pathway is the same as that in sinus rhythm but the SA node fires @ a rate of less than 60 BPM. May be normal in athletes.

Dysrhythmias (Including EKG Strips) Questions And Answers Sinus Tachycardia The conduction pathway is the same as that in sinus rhythm. The discharge rate from the sinus node increases because of vagal inhibition or sympathetic stimulation. the sinus rate is 101-200 BPM. Sinus Tachycardia S/S Dizziness, dyspnea, and hypotension due to decreased CO. Increased O2 consumption due to increased HR. Angina or an increase in infarction size may accompany this disorder in pts with CAD or AMI ...
