How does a pacemaker work?

pacemakerThe normal heart rate of a person’s 60 to 100 bpm and any variation from this particular heartbeat whether the heart is beating faster or whether the heart is beating to slow or whether the heart is beating irregularly will always cause problems sooner than later. Generally speaking, when there is any variation from the normal heartbeat for a person it usually means that it is a health problem and it is a problem in the signalling within the heart.

There is a aid you in our heart known as the sinoatrial node and this is in the upper right area of the heart. This part of the heart is basically associated with controlling the speed of heartbeats. If this part of the heart malfunctions or is not functioning properly in any way then the heartbeat would become erratic and it can become too fast or too slow or irregular as well and that is when there is a need of a pacemaker.

In such a situation a pacemaker is inserted into the body of the person which is nothing but the electrical device which controls the signal to indicate to the heart whether it should increase the rate of the heartbeat or whether it should lower down the rate of the heartbeat or whether it should keep the rate of the heartbeat constant. As our overall health and immunity system deteriorates, generation by generation the need of the pacemakers is actually going up.

What is a pacemaker?


Pacemaker is nothing but an electronic device which prevents the abnormal heartbeat and ensures that the heartbeat is always within the required amount. The different parts of the pacemaker include a battery and a generator of the electrical signal with the help of a microchip and connectors which are embedded with sensors at the end. The battery is used to ensure that the pacemaker is already working and it provides the power to the generator. These are not in direct contact with the body but are in box which is made of thin metal casing. Whatever signals are generated by the generator are connected to the heart with the help of the connectors which have sensors.

For the pacemaker to work properly it has to 1st monitor the current heartbeat and only once it is able to monitor the current heartbeat cannot control the heartbeat. The wires of the pacemaker are directly connected to the heart and therefore they can send the electrical signals to the microchip depending on the current heartbeat which you are having. This is where the sensors at the end of the connectors come into play.

Over the years there have been a lot of advancement in the technology which is being used in the pacemaker and therefore these days if you’re installing the advanced pacemakers they can help you in monitoring the BP as well along with the blood temperature everything and other vital components of the cardiac system. The current pacemakers taken to walk on the activity which you are currently doing as well and accordingly adjust your heartbeat. In order to adjust the pacemaker according to your requirement the pacemaker also records the electrical rhythm and the way in which your art functions and this information would help your doctor and adjusting the pacemaker according to your needs.

The pacemaker can be adjusted with the help of an external computer device and it is not necessary that in order to adjust the pacemaker you had to bring it out of the body again and again.

The number of connectors in the pacemaker can change from 1 to 3 depending on the need. These connectors are placed in the different parts of the heart.

The different parts of the heart are known as the chambers of the heart and if the pacemaker is a symbol chamber pacemaker then it would be sending the signal is to the right ventricle which is situated in the lower right part of your heart.

The next option which you have got is that offer dual chamber pacemaker and this would have a couple of connectors to connect to 2 different chambers of the heart. These two chambers are the right ventricle as well as the right atrium. These signals help the respective chamber of the heart’s to coordinate the contraction and expansion depending on whether the heartbeat needs to be increased or depending on whether the heartbeat needs to be decreased.

The third option is the pacemaker which is able to connect to 3 chambers of the heart and in this both of the ventricles are connected and only one atrium is connected. The coordination is done between the two ventricles with the help of the electrical signal which ensures that the contraction and expansion is controlled. This type of pacemaker is technically called as the cardiac resynchronisation therapy device.

Programming of the pacemaker:

As we mentioned about the pacemaker is programmed to detect the heartbeat and to send the signals accordingly. The type of programming can be of two different types ranging from the demand pacing to the rate responsive pacing..

The demand pacemaker works on the principle of continuously monitoring the activity of your heart and the heartbeats and whenever there is a slowdown in the activity in your heart rate sensor signal to the pacemaker. The signal is also generated when you’re heart misses a heartbeat.

The rate responsive pacemaker is actually much more advanced as compared to the demand pacemaker because it monitors the heartbeat as well as the BP as well as the blood temperature and the cardiac functions to better understand the functioning of the heart and depending on the situation it can send the electrical signals to either increase the heartbeat or decrease the heartbeat.

The type of pacemaker which you would be needing would always be determined by your doctor.

This is how a pacemaker works and it ensures that your heart is beating properly.
