Human genes for sick sinus syndrome

Sick sinus syndrome [DOID:13884]

Sick sinus syndrome, also called sinus node dysfunction, is a group of abnormal heart rhythms (arrhythmias) presumably caused by a malfunction of the sinus node, the heart's primary pacemaker. Bradycardia-tachycardia syndrome is a variant of sick sinus syndrome in which slow arrhythmias and fast arrhythmias alternate. In recent years, the syndrome has become increasingly prevalent in dogs. The reason why is unknown.
