Pulse wave Doppler interrogation of the right ventricular outflow tract. Panel A represents the time to peak velocity of the Doppler envelope, or Acceleration Time (AcT)=158ms, consistent with normal mean pulmonary artery pressure. Panel B illustrates an AcT=68ms, in a patient with a mean pulmonary artery pressure of 42 mmHg.
