Sinus tachycardia oc...

What is Arrhythmia? Abnormally with: Speed (bradycardia vs. tachycardia) OR Rhythm: Origin (sinus vs atrial vs ventricular) Describe the Conduction pathway? 1) Electrical impulses begin at the SA node - under vagus nerve control: parasympathetic and then travel down to the AV node 2) AV node's refractory period acts as a "gate" to prevent excessive impulses from being conducted into the ventricles 3) From the AV node, the impulses then travel to the bundle of HIS 4) Action potentials sp...

NURS 420 Exam #1 Questions and Answers | 100% Verified and Updated a wide QRS is defined as - Answer-greater than .12 sec Conduction system of the heart - Answer-SA node, AV node, bundle of His, r and l bundle branches, and Purkinje fibers What is the P wave of an ECG? - Answer-atrial depolarization What is the QRS complex of an ECG? - Answer-ventricular depolarization and atrial repolarization What is the T wave of an ECG? - Answer-ventricular repolarization PR interval - Answer-delay ...

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...

How many large grid blocks on the EKG paper mark one second in time? Five (5). How long in seconds is one large block on the EKG paper? 0.2 seconds (thus, five large blocks marks 1 second in time). The vertical axis...
