buzzing the maze

few heart patients experience changes in heart rhythm also known as palpitations .in medical terms it is called arrhythmia.  

to eliminate arrhythmia electric current is passed through the heart muscle , which sets the abnormal beats to normal . the procedure is maze . maze is but a drawing of few lines on the heart and blocking abnormal firing of extra nodal points . and synchronised beating of heart ensues .

more than 80 % success rate is achieved . those patients are put on simultaneous antiarrythmogic drugs such as amiodarone . 

patient selection is mandatory for planning MAZE procedure during a surgery . chronic atrial fibrillation more than 6 months duration , and left atrium large than 60 mm will not benefit from the procedure . in patients who have undergone MAZE extraprecaution need  to be employed in form of pacing wires are put in situ to be able to attach to pacemaker if need be .
