  • Most common chromosomal abnormality associated with TOF is 22q11.2 microdeletion 
  • Amiodarone is appropriate to prevents recurrent Afib with nonischemic CMP and class III congestive heart failure
  • HTN, serum potassium borderline low, sodium 145 & bicarbonate 30 near upper limit - primary aldosteronism, test plasma renin activity and aldosterone concentration
  • Referral of patient for biventricular pacing is based on QRS duration more than 150 ms 
  • In S. aureus native valve endocarditis, antibiotic therapy alone is often curative 
  • After Vfib, for each minute CPR and defibrillation are delayed, probability of survival is decreased by 10%

  • T-wave inversions, raised troponin, severe LV dysfunction - coronary angiography
