Arrhythmias & Coagulation Flashcards
It shows phase 3 of the action potential-ventricular repolarization:
T wave
The following antiarrhythmic drugs slows the heart rate except:
I. Procainamide
II. Quinidine
III. Flecainide
IV. Propafenone
“I.2.3.4”
The appropriate route of administration for lidocaine
IV
This may occur when the electrical conduction pathways malfunctions
Arrhythmias
This phase is also called rapid depolarization wherein sodium ions enter the cell through fast channels
Phase 0
Specialized myocardial structure that initiates electrical impulses to stimulate contraction
SA Node
It describes the Class 1 anti-arrhythmics drugs
Sodium channel blockade
Agent of choice for determination of ventricular tachycardia and prevention of ventricular fibrillation after cardioversion
Lidocaine
The drug of choice for prompt conversion of paroxysmal SVT to sinus rhythm due to its high efficacy and very short duration of action
Adenosine
An anti-arrhythmic drug which is a calcium channel blocker is classified as
Class 4
A brand name of amiodarone
Cordarone
Drug that prolongs effective refractory period by prolonging the action potential.
Verapamil
Which of the following is important to monitor in patients receiving anti-arrhythmic drugs?
Electrolytes
antiarrhythmic drug that is associated with an adverse effect of cinchonism?
Quinidine
An example of class 2 anti-arrhythmic drugs
Propranolol
A clotting enzyme
Thrombin
A clot that floats in the blood or moves through the circulatory system
Embolus
A blood glycoprotein involved on hemostasis especially in platelet adhesion
Von Willebrand factor
T or F
Heparin has an immediate onset but short duration of action and can cross the placenta
False
How are low-molecular-weight heparins usually administered?
Subcutaneously
Arrhythmia, thrombocytopenia, varicose vein, are prone to thrombus formation
N/A
What is the purpose of International Normalized Ratio (INR) monitoring
To monitor warfarin therapy
The mechanism of action of the anticoagulant effect of warfarin derivative involves
An action that blocks the release of y-carboxylation of several glutamate residues in prothrombin.
A bivalent inhibitor of thrombin which is also used to inhibit platelet activation and useful in percutaneous coronary angioplasty
Bivalirudin
