Qualified electrophysiologists at our centre provide Cardiac Resynchronisation Therapy (CRT) with biventricular pacemakers and avoid life-threatening heart rhythm disorders with Implantable Cardioverter Defibrillators (ICDs).Qualified electro physiologists facilitates the patients with Cardiac Resynchronisation Therapy (CRT).
The electrical impulse starts in the sinus node at the top of the right atrium where the heart is signaled to beat or squeeze. By this the impulse travels through the heart’s wires to the muscles of the right and left lower chambers causing the heart to contract and beat. This system helps the heart pump in an efficient rhythm.
When there is a problem with this natural system hearts’ natural pacemaker or the wires carrying the impulses, heart beat is reduced to produce slow heart rate. An artificial pacemaker helps to reset the heart to the right rate and ensures adequate blood is pumped to the brain and other parts of the body.
Artificial pacemakers are devices which prevent slow heart rates. These are placed inside body just below the collarbone. They weigh only an ounce and are size of a large wristwatch face. A pacemaker contains a computer with memory and electrical circuits, a powerful battery generator and special wires called leads. The generator creates electrical impulses that are carried by the leads to the heart muscle, signaling it to pump.
The pacemaker implantation does not need an open heart surgery. The procedure takes only one hours. The pacemaker generator is implanted on a small pocket made under the skin. The special wires (Leads) are usually positioned in a vein near the collarbone, and then moved to the heart with the help of an X-ray machine. The leads touch the heart muscle on one end, and are connected to the pacemaker generator on the other end. The pacemaker functions by sending signals to the heart and the settings can be changed at any time. Routine monitoring, sometimes even by phone, makes sure the pacemaker is working properly and depending on its use, the battery in the generator lasts 5-10 years and must be replaced when it runs out.
Single Chamber Pacemakers: One wire that is placed in the right upper chamber (atrium) or lower chamber (ventricle).
Dual Chamber Pacemakers: Two wires, one in the right atrium and one in the right ventricle.
Biventricular Pacemakers: These are three wires, one in the right atrium, one in the right ventricle and a third one in the left ventricle. These more complicated pacemakers take more time to implant, and can be used to improve pumping in patients with heart failure.
Rate Responsive Pacemakers: These pacemakers adjust the heart rate to a patient’s level of activity. They pace faster when a patient is exercising and slower when a patient is resting.
Pacemakers may be prescribed for a number of conditions, including:
Is a condition in which the heart beats too slowly, causing symptoms such as fatigue, dizziness or fainting spells. In adults, it is defined as a heart rate of less than 60 beats per minute.
Atrial fibrillation (AFib)
Is the most common type of irregular heartbeat. A common heart rhythm disorder in which the heart beats too fast and chaotically. Sometimes, people with AFib can also have slow rhythms. Medications used to control atrial fibrillation may result in slow rhythms, which are treated by pacemakers.
Is a condition in which the heartbeat is not strong enough to carry a normal amount of blood and oxygen to the brain and other parts of the body. A special pacemaker can be programmed to increase the force of heart muscle contractions. This is called “biventricular pacing” or “resynchronization” therapy.
A condition best known as fainting or passing out. Some patients faint when their heart rate becomes too slow. A pacemaker prevents slow heart rates and can cure syncope in some patients.
