WebTiming Cycles. Every action relative to depolarisation in a pacemaker works on a timer, and the programming of an implantable pulse generator effectively comes down to the setting of various timers. These timers can complete one of two tasks; finish the cycle and completely timeout before restarting, or reset if a native P or R wave is sensed ... WebPacemakers are life-saving devices for patients that suffer from abnormal heartbeats, a condition also known as arrhythmia. Cardiologists implant pacemakers through a patient's veins and pass this into at least one chamber of his or her heart. Pacemakers are powered by small lithium batteries and include sensors ...

WebIt is easiest to think of the heart as having two separate, but equally important systems: Mechanical and Electrical. Similar to a car engine, however in this analogy your car's battery is built into the engine and gasoline is actually blood.
