Tachycardia
Can AVRT & AVNRT can be see in both healthy & sick hearts? - ANS-Yes
Definition of Non-sustained Ventricular Tachycardia - ANS-3+ consecutive ventricular
beats (if only 1-2 it just PVCs); rate >120 bpm, duration <30 seconds
Diseases associated w/ NSVT - ANS-Hypertrophic CMP (HOCM), idiopathic DCM,
Valvular heart disease, chronic CHD, LV dysfunction
First Line Treatment of Torsades in Stable Pts - ANS-IV Mg
How to distinguish SVT from Sinus Tachycardia - ANS-SVT has more sudden onset &
abrupt cessation
Management of NSVT - ANS-optimize electrolytes (esp K & Mg), BB, Amiodarone,
catheter ablation (if aberrant pathway is found)
Multifocal Atrial Tachycardia - ANS-> or = 3 P wave morphologies
Narrow Complex Tachycardia - ANS-Sinus tachy, AVNRT, orthodromic AVRT, multifocal
atrial tachycardia, afib, aflutter
Rate need to be considered Sinus Tachycardia - ANS->100 bpm
Standard of care for WPW - ANS-Catheter ablation of accessory pathway (always
ablate even if it asymptomatic d/t risk of sudden death from a fib)
SVT Mgmt in Stable Patients - ANS-Vagal maneuvers, carotid massage, adenosine,
CCB or BB, consult EP for frequent attacks
SVT Mgmt in Unstable Patients - ANS-Try vagal maneuvers & carotid massage, if
unsuccessful then DC cardioversion
This is a potentially serious arrhythmia present in 1/3rd of WPW pts - ANS-Afib (may
result in RVR-> degeneration to Vfib -> sudden death)
Torsades de Pointes Triggers - ANS-Hypokalemia, Hypomegnesium, Drugs that prolong
QTc
