How does a pacemaker work?
A pace maker senses your heart beats if your heart is pumping to slow, it will speed it up, If your heart is pumping too fast it will slow it down and if your heart is pumping at the recommended heart rate it will automatically turn it self off until needed again.
The pacemaker is made-up of three main components. The first is the battery (pulse generator, the second is the lead and the third a computerised generator. The lead is connected to the failed heart chamber and the battery (pulse generator) sends the shock/electric impulse through the lead to the heart causing the heart to beat. The wires connect the pulse generator and battery to the heart. The electrodes (Electrodes- at the end of the wires detect, sensor heart beat and send electric impulses to the heart) detect your heart's electrical activity and send data through the wires to the computer in the generator. If your heart rhythm is abnormal, the computer will direct the generator to send electrical pulses to your heart. The pulses travel through the wires to reach your heart.
The computerised generator is what the doctor keeps, it receives information of the heart's rhythm from the pulse generator (in the patent's body) allowing the doctor to continuously monitor the patient's heart beat. From this the doctor can identify whether the heart's rhythm is too fat or too slow and modify the pacemaker's programing to suit the patient's heart beat e.g if their heart beats too slow more electrical impulses will be released etc. From the computerised monitor doctors can also deduce as to whether or not the battery needs replacing.
