Cardiology Facts 4


  • WPW syndrome, regular narrow complex tachycardia - best initial treatment is vagal maneuvers (If AFib - procainamide)
  • Regular narrow QRS tachycardia, VA interval prolongation with bundle branch block is most consistent with orthodromic AVRT using accessory pathway ipsilateral to bundle branch
  • Cardiac arrest + VF + irreversible 3V-CAD (myocardial scar) - best management for VF ICD implantation
  • In first degree relatives long QT syndrome with positive genetic screen - do genetic test
  • Syncope + Bifascicular block (RBBB+LAFB) + prolonged HV in EPS (35-50 normal) - PPM, paroxysmal A fib - dual chamber PPM
  • Paroxysmal Afib. + Propafenone/fleicainide + after propafenone/flecainide, syncope bradycardia PR prolonged - tachy-brady syndrome - stop prop/fle ,do 30 day monitor for sinus pauses
  • Acute cholecystitis intraperitoneal (intermediate risk) surgery, no clinical evidence of a recent ACS, functional capacity at least 4 METs (climbing a flight of stairs) without cardiopulmonary symptoms - no additional cardiac testing is required prior to surgery
  • ETT exercise-induced ST-segment abnormality predicts a 25% risk of cardiac events over next 5 years, most likely the development of angina
