front 1 Define ischemia | back 1 lack of blood supply |
front 2 What is the electrical pathway of the heart's conduction system? | back 2 SA node->AV node->Bundle of His->Right and Left Bundle Branches->Purkinje fibers |
front 3 When the SA node is stimulated, what mechanical action happens in the heart? | back 3 Atria contract |
front 4 What has to happen for the ventricles to contract? | back 4 Electrical conduction has to pass through the AV node, down the Bundle of His, through the right and left bundle branches, into the purkinje fibers. Once they reach the Purkinje fibers, then the ventricles will contract |
front 5 sticky skin sensors that attach to the patient | back 5 electrodes |
front 6 What does the T wave represent? | back 6 Ventricular repolarization (ventricular relaxation) |
front 7 What does the P wave represent? | back 7 atrial depolarization (atrial contraction) |
front 8 A 6 second strip in Lead II is called a | back 8 rhythm strip |
front 9 Define artifact. | back 9 abnormal waveform on an EKG tracing |
front 10 What is a "flat line" rhythm | back 10 asystole |
front 11 how tall the tracing is. It is represented by 1x, 2x, or 3x. | back 11 Define amplitude/gain |
