sinus rhythm regular rhythm Set by SA node at 60 to 100 bpm P waves normal normal qrs PR 0.12 - 0.2 normal qrs less than 0.10 wide qrs is greater than 0.12 Sinus Tachycardia 100-160 bpm SA node reduced time for ventricle filling assess for SOB or chest pain a prolonged QT interval more prone to arrhythmia NSR reflects the heart's normal electrical activity, providing synchrony between the atria and the ventricles. Sinus tachycardia occurs when the sinus nod...

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. - 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 bradycardia. juncti...

What are the three types of cells in the heart? Correct Answer 1. Pacemaker Cells 2. Electrical Conduction Cells 3. Myocardial Cells What is the Mean Vector through the heart? Correct Answer Vector of electrical flow that move and to the left in the heart - where positive electricity flows If a vector from two electrodes flows closer to this vector if will have a more positive reading What is the flow of electricity through the heart? Correct Answer SA Node - AV Node - Bundle of H...

PCCN Cardiac Exam 127 Questions with Verified Answers Which of the following is the outermost lining of the heart? A. Endocardium B. Myocardium C. Transcardium D. Pericardium - CORRECT ANSWER D. Pericardium "Endo" meaning "within" is associated with the innermost lining of the heart, so eliminate A. The myocardium is associated with the heart's middle layer, so eliminate option B. The "transcardium" is somewhat of a contrived term, so eliminate C as well. The prefix in pericardium...

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...
