Atrial flutter pr qrs qt - Study guides, Class notes & Summaries

Normal cardiac impulse correct answer: Begins in the sinoatrial (SA) node in the upper right atrium and spreads over the atrial myocardium via Bachmann's bundle and internodal pathways, causing atrial contraction; then the impulse travels to the atrioventricular (AV) node through the bundle of His and down the left and right bundle branches; ends in the Purkinje fibers Purkinje fibers correct answer: Transmit the impulse to the ventricles Electrocardiogram Monitoring correct answer: Gr...

Normal Sinus Rhythm - NSR Rate: 60-100 bpm Regularity: Regular P Waves: Normal PR Interval: 0.12-0.20 s QRS Duration: 0.04-0.12 s QT Duration: 0.36-0.44 s Sinus Node - Sinus Node Problems: The SA node can: --Fire too slow (Sinus Bradycardia [SB]) --Fire too fast (Sinus Tachycardia [ST]) Sinus Bradycardia (SB) - Rate <60 bpm Etiology--SA node is depolarizing slower than normal, impulse is conducted normally --Normal PR interval and QRS interval --Once SA node fires, everythin...
