Afib - CORRECT ANSWER The impulse originates in the Atria 
• The Atrial rate is > 300 and unable to measure [N/A] 
• No discernable P waves - PRI & Atrial rhythm cannot be measured [N/A] 
• The Ventricular rhythm is irregular 
• QRS within normal limits 
• If the Ventricular rate is <100 the rhythm is controlled A-fib; 
if the Ventricular rate is > 100 the rhythm is uncontrolled A-fib 
• This is a chronic rhythm for some patients 
Treatment: controlled patients: ant...

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.

Pacemakers of the Heart correct answer: Sinoatrial (SA) node 
Atrioventricular (AV) node 
Bundle of His 
Bundle Branches 
Purkinje Fibers 
 
-SA node: p wave 
-SA node to AV node: PR segment 
-Impulse travels from Bundle of His to Bundle branches and then to Purkinje fibers: QRS complex 
-Repolarization of ventricles: T wave 
 
P wave correct answer: sinoatrial node (SA node) starts an impulse, as the wave of depolarization spreads through the atria, _______ is inscribed on the ECG 
 
AV nod...

Dysrhythmia correct answer: Any disorder of the heart beat or heart rhythm. 
Cardiac output is impaired. 
Cellular oxygenation is then also impaired 
 
Electrical problem will definitely effect the mechanical but a mechanical problem may not effect the electrical. 
 
Explaining dysrhythmias correct answer: -Classified to their site of origin 
 -SA node atrial tissue, AV node, junctional tissue (tissue around AV node), and ventricular tissue 
 
-Caused by a disturbance in impulse formation or b...
