Heart failure and resynchronization therapy of the heart
Cardiac Resynchronization therapy (CRT) is an important
Method of treatment of congestive heart failure with complaints (symptoms)
Insufficiency (CHF) in patients caused by heart muscle
With pathological changes (cardiomyopathy). Cardiomyopathy is most common
It is often caused by damage to the coronary artery (which feeds the heart with blood)
With irreversible damage, but it can also be genetic
Due to factors, viral infections, or toxins (such as, for example, toxins).
Alcohol). Symptoms usually include shortness of breath, tingling in the ankles and
Swelling of the legs, fatigue, intolerance to physical activity
Exhaustion, decreased appetite, depression and more.
It is estimated that more than 22 million people live with heart failure.
With congestive insufficiency all over the world, and every year this figure increases by another 2.
A million people have been diagnosed.
Medications for people with cardiomyopathy and heart failure
This is the basic basis of patient therapy. Stimulates the body
The release of excess fluid increases the contraction of the heart and
Reduces stress on the heart by relaxing blood vessels and blood
By reducing the pumping resistance. Treatment is important
An important component is also a lifestyle that includes regular exercise and
dietary restrictions, such as minimizing salt and liquid intake.
Reduced fluid intake, which prevents the accumulation of fluid.
Many patients with cardiomyopathy and heart failure also
There is a malfunction of the electrical system of the heart, which leads to heart attacks.
Uncoordinated (asynchronous) muscle contraction. This is even more
Reduces the ability of a weakened (abnormal) heart muscle to pump blood.
How does the electrical system of the heart work?
The heart is a muscle pump consisting of 4 chambers. 2 upper
The chamber is called the atrium, and the 2 lower ones, that is, the main pumping chambers,
are known as ventricles. Coordinated pumping of these 4 cameras
This action is controlled by the electrical system. Normal heart rate
It is stimulated by a weak electrical signal that is generated
The area of the right atrium is known as the sinoatrial
node. The electrical signal then spreads to both atria, causing
They compress and pump blood into the ventricles. Electrical signal
It then passes through an electrical control station known as
the atrioventricular node. After a second delay, the signal
enters the ventricles through special channels
called the left and right branches of the Gis cone. Hiss Conn
The lower branches break into the ventricles, thus transmitting an electrical signal
Stimulating simultaneous contraction of both ventricles. Ventricles
These simultaneous, coordinated contractions are necessary for the body and
They ensure optimal blood circulation in the lungs.
In some patients with cardiomyopathy and heart failure
It has violations in the electrical system. The most common pathology
There is a delay in the electrical conductivity of the left leg of the gis cone
Because of the blockade (LBBB). Due to a violation of the electrical signal of the left ventricle
Caused by a blockage of the gis leg of the left ventricle or a branch of the MISIS
Because both ventricles contract at the same time, and not the right ventricle first
the ventricle begins to contract, then the left one, which causes the ventricles to become
Asynchronous during compression. This uncoordinated contraction of the ventricles is uniform
It further reduces the efficiency of pumping an already weakened heart muscle.
It is known that in patients with cardiomyopathy and heart failure
, 40% have uncoordinated ventricular contractions, which
They are caused by power outages, most often by NBPW. It’s electric
The delay is visible on the electrocardiogram (ECG) in the form of an extensive QRS complex.
What is Cardiac Resynchronization therapy or CRT?
The function of CRT is to normalize ventricular coordination
Restoration of pumping function, slowing down of electrical conductivity
With overtaking caused by hiss cone blocking (also called
resynchronization). This is achieved due to the unique type of heart
Through a pacemaker. Conventional pacemakers
It is used in connection with an excessively slow heart rate
To avoid the symptoms. The pacemaker is continuously
Monitors the patient’s heart rate and provides a small, unobtrusive
Electric charging according to need. Pacemakers
Most often they have 2 electrodes, one in the right atrium, and
In the second right ventricle, CRT pacemakers have a third
An electrode that is located in a vein outside the left ventricle
Surface. This allows the simultaneous use of an electron beam pacemaker
Activate the left and right ventricles and restore
A coordinated, or synchronous, pumping function. What reduces
Electrical delay and leads to a narrowing and normalization of the QRS complex
On an ECG.
Who is the candidate for CPT?
Congestive heart failure with moderate and/or severe symptoms,
despite drug therapy
Cardiomyopathy (weakening and/or enlargement of the heart muscle)
Significant delay in the supply of electric current to the lower pumping chambers (hisis)
The blockade of Connie’s foot
Some heart failure patients suffering from heart failure
There are also candidates for resynchronization therapy (CRT)
With a high risk of sudden cardiac death from the ventricles
Arising from a rapid heartbeat. Available for these patients
A special electron beam device that can stop for a lifetime
Dangerous rapid heartbeat in case of electric shock is known as
Defibrillation. This device is called a CRTD device (D stands for
Defibrillation). The question of whether you need a CRTP or CRTD device depends on
You should consider many clinical factors and consider your own in detail
To the doctor.
What to expect from CRT?
The answer to cardiac resynchronization therapy (CRT) can be found
They vary significantly from patient to patient. Scientific research,
Which involved more than 2,000 patients from all over the world, it was shown
Moderate improvement in exercise tolerance, congestive heart failure
About failures and the quality of life of most patients.
Although these improvements can be noticeable almost
In many patients at once, in others this may not be fully realized
For weeks or months.
