Sinus rhythm one p - Study guides, Class notes & Summaries

Cardiac EKG Rhythms (Updated). Normal Sinus Rhythm Normal Sinus Rhythm ● Rate: 60-100 beats per minute ● Rhythm: Atrial and Ventricular Regular ● P Wave: Uniform in appearance, upright, normal shape, one preceding each QRS complex ● PR Interval: 0.12- 0.2 seconds ● QRS: 0.12 second or less. (If larger than 0.12- QRS is wide and there may be a bundle branch block) Sinus Bradycardia ● Rate: Less than 60 beats per minute ● Rhythm: Atrial and Ventricular Regular ● P Waves...

Automaticity correct answer: Ability to initiate an impulse at a regular interval; "pacemaker" Excitability correct answer: Ability of the heart to respond to a stimulus Conductivity correct answer: Ability of the heart to transmit an electrical impulse from one cell membrane to another Contractility correct answer: The ability of the heart muscle cells to shorten in response to an electrical stimulus Refractoriness correct answer: "Resistant to"; cannot respond to a stimulu...

Which statement is correct regarding premature ventricular complexes (PVCs)? PVCs originate from the atrium. PVCs may be unifocal or multifocal in origin. PVCs will not lead to ventricular tachycardia. PVCs only originate from one site in the ventricles. correct answers PVCs may be unifocal or multifocal in origin. A regular rhythm at a rate of 40-60 beats per minute, with narrow QRS complexes, and no visible P waves, is consistent with the presence of: atrial fibrillation. sinus bradyc...

AAH Practice Test The T Wave represents - ventricular re-polarization If the heart is in a state of asystole - There is no contraction What are the bipolar leads - I, II, and III The most common type of supraventricular Tachycardia is - AV nodal Reentrant tachycardia (AVNRT) In 2:1 AV block, the PR interval - Lengthens In sinus arrhythmia, a gradual decreasing of the heart rate is usually associated with: - Expiration When the cardiac muscle cell is stimulated, the cell is...
