The term arrhythmia refers to an abnormal heart rhythm. Normal electrical conduction typically involves transmission of electricity originating in the sinus node in the top right corner of the heart, through the AV node in the middle of the heart, and then down to the ventricles. A number of different arrhythmias may potentially affect the heart of a child.
Read MoreThe term bradycardia refers to a slow heart rate. Normal electrical conduction in a child's heart involves the generation of electricity in the sinus node in the upper right portion of the heart. Electricity then travels through both atrium to the AV node in the middle of the heart. From here, electricity is spread out through both ventricles. As electricity moves through the ventricles, heart muscle contracts.
Read MoreThe sinus node is the pacemaker of the heart. It is responsible for generating the electrical impulses that stimulate the heart muscle to contract. Sinus bradycardia refers to a slower than normal heart rate.
