Anatomy
This valve aids in right ventricular preload
Depolarization causes muscle cells to _______
Contract
Atropine, Dopamine, or Epinephrine can be used to treat:
Sinus bradycardia
This formula represents the afterload of the left heart.
Identify the name, formula, and range
SVR = [(MAP-CVP)/CO] X 80.
900-1400 dynes
This arrhythmia will be felt by all students in this course, within the next week, during a test.
Identify the rhythm and rate
Sinus tachycardia
This heart layer is responsible for muscle contractility
Myocardium
This impulse conductor has the greatest degree of automaticity and paces the heart
Sinoatrial Node
Another name for this calcium channel blocker is Diltiazem, and it is used to treat this quivering atrial condition. Identify the med name and EKG
Cardizem and Atrial fibrillation
This is the percentage of volume ejected from the left ventricle.
Identify the name, formula, and range
EF = (LVSV/LVEDV) x 100. 60-75%
This rare arrhythmia can be identified by any EKG rhythm that does not generate a palpable pulse.
Identify the rhythm and rate
PEA-0
This large coronary artery is also known as the anterior interventricular artery. When blocked- AKA THE WIDOW MAKER
Left Anterior Descending
This electrode must be placed at the intercostal level, midclavicular line. Identify the electrode and placement level
V4, 5th intercostal
This arrhythmia has a QRS > boxes. If the patient is unstable, synchronized cardio version is indicated
Ventricular tachycardia
The amount of blood ejected from the left ventricle during systole every minute.
Identify the name, formula, and range
CO = SV x HR
4-8 LPM
This arrhythmia is identified as a twisting ribbon-like pattern due to varied ventricular locations
Identify the rhythm and rate
Tosades de Pointes
The pace maker rate of the AV node is:
40 - 60 BPM
Normal length of the P-R interval _____ boxes
Less than 5
This arrhythmia is not sustainable with life (NSWL), since there is electrical activity, either of these antiarrhythmics can be administered.
Identify the rhythm and meds
Ventricular fibrillation; Amiodarone or Lidocaine
This is the average pressure within the systemic circulation system
Identify the name, formula, and range
MAP = (2D + S)/3
70 - 100 mm
This unshockable rhythm is caused by severe hypovolemia, hypoxemia, or electrolyte imbalances with no electrical activity
Asystole-0
When occluded, this vessel is responsible for a posterior myocardial infarction
Right Coronary Artery
Normal length of the QRS is _____ boxes
Less than 3 boxes
This arrhythmia has equal P-R intervals (3-5 boxes) when SUDDENLY the QRS is dropped
Second-degree Mobitz II
The total resistance to blood flow in the pulmonary system.
Identify the name, formula, and range
PVR = [(PAP-PCWP)/CO) x 80
This arrhythmia is identified by its upside-down "V" shape between the QRS and is treated with Adenosine, vagal maneuvers, or cardioversion
Identify the rhythm and rate
SVT- 150-200 BPM
