At Liv Hospital, we use advanced electrophysiology procedures to help patients take back control of their heart health. Cardiac electrophysiology is key to understanding the heart’s electrical system. It’s vital for keeping a regular heartbeat. Discover what an EP procedure is, how it helps diagnose arrhythmias, and what to expect during heart testing.
Healthy hearts send out small electrical signals. These signals make the heart muscle squeeze and pump blood. This is how our bodies get the blood they need.
An EP procedure is a special test done in an electrophysiology lab. It helps find and fix heart rhythm problems like arrhythmias. We use the latest technology to map the heart’s electrical activity and fix irregular rhythms.
This way, we offer care that’s tailored to each patient’s needs. It’s all about giving arrhythmia patients the best chance at a healthy heart.

Cardiac electrophysiology explores the heart’s electrical system. It’s key to how the heart beats in rhythm. This system ensures the heart’s chambers work together smoothly.
The heart starts with the sinoatrial (SA) node, its natural pacemaker. It sends out electrical signals. These signals then move to the atrioventricular (AV) node.
The electrical conduction pathway goes through the Bundle of His. It splits into left and right branches. Then, it reaches the Purkinje fibers, making the ventricles contract. This ensures the heart pumps blood well.
The heart’s electrical system works well in a normal heart. It starts with the SA node firing at 60-100 times per minute at rest. The signal then goes through the atria, making them contract.
It reaches the AV node, which delays it a bit. Then, it moves to the ventricles. This careful timing helps the heart beat in sync.
Arrhythmias happen when the heart’s electrical system gets disrupted. This can be due to many reasons, like abnormal automaticity or re-entry circuits.
Re-entry is a big cause. It’s when an electrical signal keeps going in circles, making the heart beat irregularly. Atrial fibrillation and ventricular tachycardia are examples of arrhythmias caused by this.
Knowing how arrhythmias start is key to treating them. Studies in cardiac electrophysiology help find the cause. This guides the right treatment.

Electrophysiology (EP) procedures have changed how we diagnose and treat heart rhythm problems. These advanced tests are done by cardiologists who specialize in electrophysiology. They aim to give patients the best possible care.
An electrophysiology study, or EP study, checks your heart’s electrical system. The main goal is to find and fix heart rhythm problems. This is done by using catheters through veins in the groin or neck to reach the heart.
During the test, doctors can see how the heart’s electrical activity works. They can find and fix any problems. The main goals are to figure out the type of arrhythmia, understand how it works, and find the best treatment.
Electrophysiology testing has grown a lot over time. It used to just help diagnose problems, but now it also helps treat them. New technologies like 3D mapping systems and advanced catheters make these tests more precise and effective.
Thanks to these advancements, doctors now understand arrhythmias better. This knowledge helps them find and fix problems more effectively. This has greatly improved patient care.
EP procedures are key for finding and fixing many heart rhythm problems. These include SVT, atrial flutter, atrial fibrillation, and ventricular tachycardia. Doctors use these tests to find the source of the problem and treat it with things like catheter ablation or device implantation.
These tests can diagnose and treat many complex conditions. Being able to accurately diagnose and treat these problems has greatly improved patient care in cardiology.
EP procedures are key in cardiology. They help diagnose and treat heart rhythm problems. These methods have changed how we manage heart rhythm disorders, giving patients better treatment options.

Safety Measures in the EP Lab:
To decide if someone needs an EP procedure, we look at their heart health. We check their symptoms, medical history, and test results. This helps us see if they need an EP procedure.
Some symptoms might lead to an EP procedure. These include palpitations, dizziness, fainting spells, and shortness of breath. These signs can mean there’s an arrhythmia or heart rhythm disorder that needs to be checked.
We talk about these symptoms in detail during the first meeting. This helps us figure out if an EP procedure is needed to find and possibly treat the problem.
Some arrhythmias are more likely to need an EP procedure. These include atrial fibrillation, supraventricular tachycardia (SVT), and ventricular tachycardia. Our team uses special tools during the procedure to find out the exact arrhythmia and where it starts.
Modern treatments for atrial fibrillation can work for over 70 percent of patients. This makes it a hopeful treatment option for many.
EP studies are key for checking people with unexplained fainting and sudden cardiac death risk. We use what we learn from the procedure to see if there are dangerous arrhythmias that need to be fixed.
By finding out who’s at high risk of sudden cardiac death, we can suggest treatments. This might include getting a cardioverter-defibrillator (ICD) to prevent such events.
In short, an EP procedure is vital for diagnosing certain arrhythmia symptoms or sudden cardiac death risk. Knowing who needs it helps us offer the right treatment. This improves patient outcomes and quality of life.
Getting ready for an EP procedure is key to its success and your safety. We know it can be scary, but being prepared helps a lot. It makes the whole experience less stressful and smoother.
Before the procedure, we do several tests. These tests give us important info about your heart. They include:
