Of all the body parts, if we have to select one body part, that is the most important out of all or which is the most critical one, then the answer will be Heart. We have been listening this from childhood and as we grow up, we realize that this is all the way true. The role of our heart is to pump blood to all the parts of our body and circulate it everywhere. It is very important to keep our heart running and making it work in an efficient manner. But sometimes, there are irregularities noticed which are determined by electrical physiology.

What is electrical physiology?

Some humans complain of irregular heartbeats. Electrical physiology is the test which is done to check why these abnormal heart beats are taking place with the help of an electrical activity. With the help of this test, we can find the origin of the problem and what kind of treatment is needed. If the problem is minor, then it can be solved with the help of medicines and for major problems there are options such as pacemaker and cardiac surgery.

Preparation for electrical physiology

When undergoing a surgery, this can be a complex process. It is important to be psychologically ready so that you don’t feel any discomfort while this procedure takes place. It is advised not to eat or drink anything for up to 10 hours before electrical physiology otherwise vomiting can occur and can lead to bleeding. Your doctor should know about all the medicines that you are consuming so that there is no side effect. After the procedure is completed, driving is a strict no. Call someone who will drive you back home.

Procedure of electrical physiology

There is a special room for this procedure. It is known as Cath lab or electro physiology room. The procedure starts with the insertion of IV tubes so that there are no hydration problems and can also help in providing anesthesia and other drugs. Then, a catheter will be inserted in your vein. The catheter will make contact with heart at the insertion point and electrical pulses will be sent which will make your heart beat at different speed and generate electric signals which will be recorded by special catheters. This whole process is called cardiac mapping. This process allows doctor to see form where exactly abnormalities are coming. After the process is completed, IV tubes are removed and to stop bleeding from the holes, pressure will be applied to the area.


The procedure lasts for 2-4 hours and the patient is advised to rest for 3-4 hours. Before taking any medicines, consultation from your doctor is a must.

What are the complications involved?

After the IV tubes and catheter are removed, pressure is applied to the area which can result to swelling of the area. Dizziness can be observed due to abnormal heartbeat. There are other complications which are very rare but can be serious such as damage to a blood vessel, infection from the insertion of IV tube etc.
