Approximate Synonyms
  • Ventricular premature beats
Clinical Information
  • A type of cardiac arrhythmia with premature contractions of the heart ventricles. It is characterized by the premature qrs complex on ecg that is of abnormal shape and great duration (generally >129 msec). It is the most common form of all cardiac arrhythmias. Premature ventricular complexes have no clinical significance except in concurrence with heart diseases.
  • Ectopic impulses originating in the ventricles.
  • Premature ventricular beats, the most common of all arrhythmias; in the absence of heart disease, they are not of great clinical significance, but in patients with coronary disease, they represent a constant danger of ventricular tachycardia or fibrillation and sudden death.
ICD-10-CM I49.3 is grouped within Diagnostic Related Group(s) (MS-DRG v37.0):
  • 308 Cardiac arrhythmia and conduction disorders with mcc
  • 309 Cardiac arrhythmia and conduction disorders with cc
  • 310 Cardiac arrhythmia and conduction disorders without cc/mcc
