LV filling pressures in Sinus Tachycardia

  • Assessment of LV filling pressures in Sinus Tachycardia

    Mitral inflow pattern with predominant early LV filling in patients with EFs <50%
    IVRT <70 msec is specific (79%)
    Pulmonary vein systolic filling fraction <40% is specific (88%)
    Average E/e' >14 (this cutoff has highest specificity but low sensitivity)
    When E and A velocities are partially or completely fused, the presence of a compensatory period after premature beats often leads to separation of E and A velocities which can be used for assessment of diastolic function
