Cardiomyopathies w/ Alfrey
What is an intrinsic myocardial dysfunction!
What are the two elements of cardiac function?
What is electrical activity and mechanical activity!
An arrhythmia is...
What is a disturbance in the rate, regularity, site of origin, or conduction of the cardiac electrical impulse!
What is Class 0 for anti-arrhythmics
What is the Pacemaker channel (HCN) blocker!
What is Class I of the anti-arrhythmics?
What are the sodium channel blockers.
What are the 3 categories of cardiomyopathies?
What is dilated, hypertrophic, and restrictive cardiomyopathies!
How can we describe Sinus Tach?
What is that there is a P wave before every QRS, it is regular, HR >100bpm, and may be normal (exercise) or pathologic due to underlying disease!
How can we describe sinus bradycardia?
What is P waves before every QRS, regular, HR <60bpm, andmay be normal or pathologic.
What is Class III of anti-arrhythmics?
What is mexiletine!
What is the MC genetic cause of a dilated cardiomyopathy?
What is a mutation within the TTN gene, which encodes titin. Most cases are inherited AD!
How can we describe atrial fibrillation?
What is chaotic atrial electrical activity with no p-waves. Random firing overwhelming the AV node. Described as irregularly irregular!
How can we describe Second Degree Type I heart block?
What is not all P waves are conducted to the ventricles. PR interval will increase with each beat until there is a DROPPED beat!
What are some side effects related to procainamide?
What is a transient lupus-like syndrome OR agranulocytosis.
What is our first choice if we have Torsades de Pointes?
What is Magnesium sulfate!
What are the mutations associated with hypertrophic cardiomyopathy?
What is mutations involving the myosin binding protein C and beta-myosin heavy chain!
How can we describe Torsades de Pointes?
What is wide QRS complexes, associated with a prolonged QT interval. Described as the "twisting of the points," in which complexes spiral around the baseline.
What TWO arrhythmias require a pacemaker for treatment?
What is a Second Degree Type II and a Third Degree (complete heart block).
What is one thing to remember regarding amiodarone and its QT prolongation?
What is that it DOES NOT trigger torsades de pointe.
What is the DOC for prompt conversion of paroxysmal SVT? It can be used in pregnancy...
What is adenosine!
What is the MC cardiac tumor in adults? What is the MC cardiac tumor in children?
What is the myxoma and the rhabdomyoma!
What is to DEFIBRILLATE!
How do we treat asystole?
What is starting CHEST COMPRESSIONS and using epinephrine! ELECTRICITY IS NOT INDICATED!
What are the 4 main side effects of Amiodarone?
What is blue-gray skin discoloration, thyroid abnormalities (hypo/hyper), neurological effects, and pulmonary fibrosis (BOARD HIGH YIELD).
What are the 3 Class III medications that can cause Torsades de Pointes?
What are ibutilide, dofetilide, and sotalol!
