In cardiology, a wandering pacemaker is an atrial arrhythmia that occurs when the natural cardiac pacemaker site shifts between the SA node, the atria, and/or the AV node. The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify Diseases The following is a list of codes for International Statistical Classification of Diseases and Related Health Problems. Cardiology (from Greek grc καρδίᾱ kardiā, "heart" and grc -λογία -logia) is the branch of Internal medicine In Anatomy, the atrium (plural atria) refers to a chamber or space Dysrhythmia redirects here For the American band see Dysrhythmia (band. For other uses see Pacemaker (disambiguation A pacemaker (or artificial pacemaker, so as not to be confused with the heart's natural pacemaker This shifting of the pacemaker from the SA node to adjacent tissues is manifested electrocardiographically by transient changes in the size shape and direction of the P waves. A wandering pacemaker is usually caused by varying vagal tone. With increased vagal tone the SA Node slows,allowing a pacemaker in the atria or AV Nodal area,which may become slightly faster briefly. After vagal tone decreases the SA Node assumes pacemaker. The vagus nerve (ˈveɪˌgəs (VĀ-gəs (also called pneumogastric nerve or cranial nerve X) is the tenth of twelve paired Cranial nerves, and is the
