BAD GENES
GRAB (your chest) BAG
100
When SA gives up the ghost. Treated with pacing.
What is Sick Sinus Syndrome?
100
Repetitive, monomorphic tachycardia with rate most commonly around 150 bpm.
What is atrial flutter?
100
3 or more consecutive ventricular complexes (>100 bpm) that terminates spontaneously in less than 30 seconds, without hemodynamic consequences.
What is non-sustained VT?
100
Slurred R, prolonged PR, widened QRS.
What is WPW?
100
Medication of choice for symptomatic bradyarrhthmias.
What is atropine?
200
When the Q's don't mind their P's and become divorced.
What is 3rd Degree Heart (AV) Block?
200
DAILY DOUBLE
Reduces the risk of stroke from 6%-7% per year to 3.6% per year in chronic atrial fibrillation in high risk patients.
200
> 50% RR interval (rate 60-100) or > 440 msec
What is: long QT?
200
This AD inherited disorder is associated with asymmetric LVH, murmur worsened with Valsalva, and a predisposition toward atrial and unstable ventricular arrhythmias. Risk of sudden cardiac death is increased when condition presents at a young age.
What is HOCM?
200
Useful in pharmacologic cardioversion and rate control in atrial fibrillation. Also known to decrease hospitalizations in CHF without improving overall mortality.
What is digoxin?
300
The rate below which ventricular escape can occur (intrinsic ventricular pacemaker).
What is 40 bpm?
300
Functional dissociation of the AV node into "slow" and "fast" pathways, most commonly with slow antegrade and fast retrograde conduction, leading to a shortened refractory period.
What is AVNRT?
300
A variant of polymorphic VT that is typically preceded by a prolonged QT interval in sinus rhythm.
What is Torsades de pointes?
300
Genetic defect causing abnormal cardiac repolarization and risk for sudden death, may also be drug-induced.
What is long QT syndrome?
300
Why WPW must be ruled out as the cause of SVT before AVN-blocking agents are given.
What is: causes an unpredictable effect on accessory pathway refractoriness?
400
Pacing stimulus does not generate evidence of myocardial depolarization
What is failure to capture? http://lifeinthefastlane.com/wp-content/uploads/2012/01/pacemaker-failure.jpg
400
Causes atrial flutter to become irregular.
What is variable AV conduction?
400
The best initial drug for treatment of an acute wide complex tachycardia?
What is amiodarone?
400
DAILY DOUBLE
ECG abnormality which can make SVT difficult to distinguish from VT.
400
Leads to diagnosis in 15 percent or less when used to evaluate unexplained syncope, near syncope, dizziness or unexplained recurrent palpitations over a 24 hour period.
What is an ambulatory ECG (Holter)?
500
One way to differentiate type I (Wenckebach) from type II in 2:1 2nd degree AV block.
What is? 1. Concominant first degree AV block (Type I) 2. Improved (Type I) or worsened (Type II) conduction with increased sympathetic input (or atropine) http://en.wikipedia.org/wiki/File:Sinus_rhythm_with_3-to-2_and_2-to-1_Type_II_A-V_block.png
500
Typically involves an accessory bypass tract. Can have retrograde P waves and is associated with pre-excitation syndromes.
What is AVRT?
500
2 features of VT distinguishing it from SVT with aberrancy.
What are? 1. AV dissociation 2. Capture or fusion beats 3. LBBB morphology with right axis deviation 4. Absence of RS complex in all precordial leads 5. R to S interval > 100 msec in one precordial lead
500
Genetic defect, often with EKG findings including ST elevations and RBBB-like pattern, and associated with VT/VF and sudden death.
What is Brugada Syndrome?
500
The CHADS2 score of a 72 year old male with hypertension, mild congestive heart failure and a history of TIA.
