Why Tachycardia is one of the most important factors in increasing LA pressures in mitral stenosis?

Why Tachycardia is one of the most important factors in increasing LA pressures in mitral stenosis?

  1. Tachycardia significantly reduces diastolic filling time
  2. Reduce forward flow to LV
  3. Increase in LA Pressure
  4. Which leads to high mitral valve gradients
  5. That causes worsening of symptoms
