The pulses reach the heart through the wires and ensure its normal functioning.

The computer will direct the generator to send electrical impulses to the heart if it finds that the heart rhythm is abnormal. The heart’s electrical activity is monitored by the electrodes, which then sends the data through the wires to the computer located in the generator. The generator is connected to the heart with the help of the wires and the battery powers the generator. A pacemaker consists of a computerized generator, a battery and wires which have sensors at their tips. The most common causes why a person needs to get a pacemaker installed are if he/she suffers from bradycardia or blockage of the heart.

A pacemaker helps a person to get relief from some of these symptoms and can also help a person with an abnormal heart rhythm to lead a better life. If the condition gets too severe, a person’s vital organs may get damaged or he/she may even lose consciousness. During such conditions, the heart is unable to pump blood properly to the body and this can cause symptoms like fatigue, shortness of breath and/or fainting.

Tachycardia and bradycardia are conditions that occur when the heartbeat is too fast or too slow respectively. They also help to treat a disorder called long QT syndrome that can lead to dangerous arrhythmias. Some pacemakers which are used to treat heart failure are called resynchronization therapy devices and they help to coordinate electrical signaling between the ventricles. Pacemakers can help to speed up a slow heart rhythm, ensure that the ventricles contract properly if the atria are not working properly, help to control the heart if it has an abnormal rhythm, coordinates electrical signaling between the lower and the upper parts of the heart. The pacemaker uses low-energy electrical pulses to overcome the faulty signaling. Arrhythmia is caused due to faulty electrical signaling in the heart. A person who suffers from this condition either has his/her beating too fast or too slow or in an irregular rhythm. It is a small device that is primarily used to treat arrhythmias, which happens when there is a problem with the rate or rhythm of the heartbeat. A person who has abnormal heart rhythms may require a pacemaker to be placed in the heart or abdomen.
