The sinoatrial node would fire another impulse which would initiate the cycle to begin again. Arrhythmias is when the rate or rhythm of the heartbeat has a defect. To correct this a pacemaker can be used. A pacemaker is a small device that is placed in the chest or even the abdomen that is used to control abnormal heart rhythms. The pacemaker uses energy electrical (low) pulses to prompt the heart to beat at a normal rate. There are four valves in the heart which prevents the backflow of blood. They are the bicuspid valve, tricuspid valve, aortic semilunar valve and the pulmonary semilunar valve. The bicuspid valve is located between the left atrium and ventricle. The tricuspid valve is located between the right atrium and ventricle. The aortic semilunar valve is located between the left ventricle and the aorta and the pulmonary semilunar valve is located between the right ventricle and the
