arrhythmia

1. An abnormal rate of muscle contractions in the heart (synset 114134156)
   is a type of: cardiopathy, heart disease - a disease of the heart
   subtypes:

   • flutter - abnormally rapid beating of the auricles of the heart (especially in a regular rhythm); can result in heart block
   • cantering rhythm, gallop rhythm - cardiac rhythm characterized by the presence of an extra sound; can indicate a heart abnormality
   • atrial fibrillation - fibrillation of the muscles of the atria of the heart
   • bradycardia - abnormally slow heartbeat
   • adams-stokes syndrome, atrioventricular block, heart block, stokes-adams syndrome - recurrent sudden attacks of unconsciousness caused by impaired conduction of the impulse that regulates the heartbeat
   • premature ventricular contraction, pvc - irregularity of cardiac rhythm; recurrent occurrences can be a precursor of ventricular fibrillation
   • tachycardia - abnormally rapid heartbeat (over 100 beats per minute)
   • ventricular fibrillation - fibrillation of heart muscles resulting in interference with rhythmic contractions of the ventricles and possibly leading to cardiac arrest
   same as: cardiac arrhythmia
