Cardiac Test Flashcards
RA
right forearm/ wrist
LA
Left forearm / wrist
LL
Left lower leg, proximal to ankle
RL
Right lower leg, proximal to ankle
V1
4th intercostal space, right sternal edge
V2
4th intercostal space, left sternal edge
V3
Midway between V2 and V4
V4
5th intercoastal space, midclavicular line
V5
Anterior axillary line in straight line with V4
V6
mid-axillary line with straight line with V4 and V5
What does an EKG show?
Conduction of electricity through the heart
How fast should the PR interval be
0.12-0.20
__ wave is the electrical impulse starting at the SA node and spreading through the atria
P
___ interval is the time needed for the SA to conduct electricity to the AV node
PR
The __ wave is the first negative deflection after the P wave
Q
QRS interval should be less than:
0.12
__ wave ventricle repolarization (resting) state of the heart
T
QT wave should be between :
0.32-0.40
A prolonged QT can lead to what ekg rhythm
**Hypomag can cause this
Torsades de points
ST elevation is tissue _______
death
ST depression is tissue __________
ischemia
What is a normal HR
60-100
What medication should be given slow IVP for symptomatic bradycardia
Atropine
Sinus Tach golden rule =
treat the cause!
What medication is given for SVT?
Adenosine - this stops heart, push quickly- IV must be close to the heart
What are other treatments for SVT?
Synchronized cardioversion, ablation, vagal maneuvers
Electrical impulse starts in the atria but not the SA node. A premature impulse before the SA fires is known as what?
Premature Atrial Contraction (PAC)
How do you treat a new diagnosis of A-flutter?
Adenosine
Cardioversion
How do you treat an old diagnosis of A-flutter
Anticoags
Cardioversion
Antiarrhythmic (amiodarone)
What medication treats atrial and ventricular arrhythmias?
Amiodarone
How does amiodarone work?
Prolongs repolarization
What are the common treatments for Afib?
Cardioversion
Anticoags
Antiarrhythmics
Beta-blocker/Calcium Channel blocker
A timed delivery of electrical current through a defibrillator is known as what?
Cardioversion
What is a commonly used antiarrhythmic for Afib?
Digoxin
_________ rhythms signal in the AV node, not the SA. If symptomatic, you should treat it like sinus brady
Junctional
A patient who has ventricular fibrillation has no pulse (TRUE OR FALSE)
TRUE - start CPR. Defib ASAP
