the three rhythms are 3rd degree HB, Torsade's de pointes, sinus rhythm know what the first thing you do on a call is BSI, Scene Safe, Use PPE Know what Afib RVR looks like know difference between alkalosis and acidosis A-fib: stable patient, treatment? BB, Ca-channel blockers (dilitiazem), digoxin; once you achieve rate control anticoagulate with warfarin to INR 2-3, mostly Cardizem-(designed to slow down conduction through the AV node. A-fib rvr-unstable ...

PSG Boards Exam Prep What is Atrial Fibrillation? - In atrial fibrillation, the electrical activity of the heart is uncoordinated, with electricity traveling about the upper chambers in a chaotic fashion, causing the upper chambers to quiver (like a "bag of worms") and contract inefficiently or not at all. Common in elderly and those with heart disease. What is Atrial Flutter? - Atrial flutter causes a rapid but coordinated electrical stimulation of the upper chamber of the heart, of...

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...
