Long QT Syndrome
Long QT Syndrome (LQTS) produces prolonged ventricular repolarisation -> predisposes to malignant ventricular arrhythmias

Nasal intubation
nasal intubation may be performed blind or with fiberoptic assistance. Indicated when oral intubation is not feasible
Cardiac Output
Cardiac Output (CO) = Stroke Volume (SV) x Heart rate (HR) CO = SV x HR changes based on exercise, age and body size. normal adult = 5L/min Stroke Volume (SV) determined by: Preload Afterload Contractility
