A biventricular pacemaker is a battery-operated device used to treat delay in contractions of the lower chambers of the heart

A biventricular pacemaker is a battery-operated device used to care for filibuster in contractions of the lower chambers of the center (ventricles). Every bit per research, patients with a biventricular pacemaker have better survival rates afterwards the diagnosis is made. The average life increases approximately betwixt viii.5 and xx years, depending on the overall health, age, and lifestyle. All subgroup women had significantly longer survival than men. If the patients follow a few simple precautions and the doctor's schedule for periodic follow-ups, the pacemaker should non noticeably impact their lifestyle in any negative way.

What is ejection fraction?

Ejection fraction is a measure of blood that is pumped out past the left ventricle of the heart and is expressed in pct. A normal ejection fraction usually lies between fifty% and 70%. Patients with centre failure take a depression ejection fraction, which hampers the claret supply to various parts of the body and leads to symptoms of heart failure. The symptoms are shortness of jiff, dry cough, swelling of the ankles and legs, weight gain, increased urination, fatigue, and rapid or irregular heartbeat.

What is a biventricular pacemaker?

A biventricular pacemaker is a small-scale, battery-operated device that helps maintain a normal and coordinated heartbeat past sending electrical impulses to the heart. It is used to synchronize the contractions of the left ventricle with the correct ventricle to improve the ejection fraction in patients with astringent and moderately astringent symptoms of eye failure. A biventricular pacemaker is typically used in people with symptomatic centre failure. This is diagnosed through an echocardiogram (ECG), which reveals that the walls of their ventricles (main pumping chambers) are not pumping in a coordinated manner.

Biventricular implantation is considered in patients with heart failure and

Severe or moderately severe middle failure symptoms.
Delayed electrical activation of the center.
Either a risk or history of cardiac abort.
On long-term medications for middle failure.

A biventricular pacemaker can be implanted either by an endocardial (transvenous) arroyo or epicardial approach.

Endocardial, transvenous approach:This is the nigh common and simple method of pacemaker implantation. A lead is inserted into the vein present under the collar os and guided to the heart. The tip of the lead attaches to the heart musculus. The other end is fastened to the pulse generator, which is placed nether the skin in the upper chest.
Epicardial approach:The md opens the chest to attach the tip of the atomic number 82 outside the heart. The other end is fastened to the pulse generator, which is placed nether the pare in the belly.

When the eye rate drops below the rate set with the pacemaker, information technology senses the driblet and transmits electrical impulses to the left and right ventricles to contract simultaneously. This improves the ejection fraction and cardiac function. The pb placed in the right atrium helps the center to part in a more than counterbalanced manner.

Care:

Biventricular pacemaker implantation is also called cardiac synchronization therapy and is only a part of any comprehensive heart failure direction program. Medications, lifestyle changes, and regular follow-ups with a cardiac specialist are all crucial for managing the symptoms and improving the quality of life in patients with eye failure.

Patients with a biventricular implantable cardioverter defibrillator (ICD) must maintain a distance from magnetic resonance imaging (MRI) machines and hand-held security wands, which contain stiff magnets. They should as well avert annihilation with a strong magnetic field, such every bit radio transmitting towers and loftier-powered electrical equipment. Patients may exist provided with a medical card that volition let them avert metal detectors in public places such as airports and courthouses. Patients volition periodically accept to replace the generator'due south bombardment. The procedure is similar to that of the original implantation but less involved and time-consuming.
