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 .
