This value set includes codes based on the following rules:

• Include these codes as defined in http://dicom.nema.org/resources/ontology/DCM

  Code	Display	Definition
  130700	Mitral Valve Opening	The point in time in a cardiac cycle when the mitral valve nominally begins opening.
  130699	Mitral Valve Closure	The point in time in a cardiac cycle when the mitral valve nominally finishes closing.
  125324	Full Cardiac Cycle	The period of the entire cardiac cycle. E.g. from End Systole of one heartbeat to End Systole of the next heartbeat.
  125323	AR-wave	The period of retrograde flow into the pulmonary vein during atrial contraction.
  125322	Atrial Diastolic Filling (D-wave)	The period of atrial diastolic filling.
  130702	Aortic Valve Opening	The point in time in a cardiac cycle when the aortic valve nominally begins opening.
  125321	Pre-ejection Period	The period between onset of ventricular contraction and the beginning of antegrade blood flow out of the ventricle.
  130701	Aortic Valve Closure	The point in time in a cardiac cycle when the aortic valve nominally finishes closing.
  125320	Electromechanical Delay	The period of time between the onset of muscle activation and the onset of force or motion.
