    What is (are) chronic atrial and intestinal dysrhythmia ?
    ### Response:
    Chronic atrial and intestinal dysrhythmia (CAID) is a disorder affecting the heart and the digestive system. CAID disrupts the normal rhythm of the heartbeat; affected individuals have a heart rhythm abnormality called sick sinus syndrome. The disorder also impairs the rhythmic muscle contractions that propel food through the intestines (peristalsis), causing a digestive condition called intestinal pseudo-obstruction.
