The only person who can diagnose pathological conditions and to identify ways to appropriate treatment is a specialist doctor only. So, if you feel that you are suffering from any kind of defect or health problem, you should consult a specialist doctor immediately to avoid the development of symptoms.

Ventricular fibrillation is abnormality the heart rate leads to a fast shrinking in these muscles also leads to irregular, can lead to ventricular fibrillation to a weakness in the blood circulation within the body, and encourages physicians to to this situation are more reasons that lead to the disruption of the work of the heart, or sudden death.

There are a lot of factors that can cause ventricular fibrillation, including ischaemic heart disease, there are other factors that affect the rate and regularity of heart beats, such as imbalance in electrolytes like calcium deficiency in the blood or a deficiency of magnesium in the blood or a lack of potassium in the blood, as the oil shocks in addition to accidents or surgical operations or inhalation of toxic gases or exposure to electrical or drug abuse and some medications such as antidepressants can cause ventricular fibrillation.

Is characterized by ventricular fibrillation by a combination of symptoms such as palpitations, abnormal heart and the feeling of tightness in the chest and blue in the skin color in addition to shortness of breath, and can lead in advanced cases to loss of consciousness, these symptoms this is what appear on all affected by this disease, but through early diagnosis and determine treatment options early, treatment can be more effective and lead to saving the lives of many patients.

Concentrated treatment mainly in cases of emergency to remove the defibrillator, as there are many treatments ambulatory that can be done in cases of danger, such as cardiopulmonary resuscitation and heart massage and the use of some types of medicines, as for diagnosis, the best way is electrocardiography or echocardiography, or imaging the chest X-ray.

What is ventricular fibrillation? a

Ventricular fibrillation is a malfunction in the work of the heart leads to the beats of fast and disciplined, it can be observed the patient who is suffering from ventricular fibrillation some cases, such as:

  • Increased heart rate and speed.
  • Tachycardia and consistency.
  • Severe change in the work of the heart.
  • The lack of effectiveness of the heart in the performance of his duties and functions.

In the latter case, a malfunction occurs overlapping in heart rate during the contraction, this leads to the response is effective. When muscle contraction in the heart, does not specify the process of relaxation during the appropriate time period, meaning that the heart muscle will need to a certain period of time to shrink and relax, this period differ from the period of time the natural.

The lack of regularity and coordination between the contractions of the cells and muscle fibers in the heart muscle leads to compression on the ventricle affects the process of opening the valves aortic and pulmonary functions blood in the body in general.

All of these changes and imbalances that occur in the work of the heart lead to a malfunction in the process of pumping blood to the body, happens as a result imbalance in the amount of oxygen that is sent through the blood circulation towards the body organs and tissues various, and if there was a problem in the process of pumping the blood, the person will suffer mostly from the lack of oxygen, and thus will be members of a different body is able to discharge its functions effectively. More member affected by this problem is the heart muscle itself, due to lack of oxygen acute, can stop the heart permanently for work inevitably leads to the death of the person as a result of stopped blood circulation, for this, ventricular fibrillation is a serious medical condition that should be dealt with quickly and treated in its beginning.

In summary, ventricular fibrillation is abnormality in the rhythm of the heart beat, this is one of the most types of disorders that affect the heart and lead to death or cardiac arrest.

It is estimated that about 80 – 85 percent of persons who die as a result of cardiac arrest suffer from ventricular fibrillation, and that this condition affects one in every thousand people in the world, and men more affected than women, so that women and three men suffer from this flaw, for every one woman.

Risk factors that increase the likelihood of injury to shake, ventricular

There are some factors that increase the likelihood of injury to shake, ventricular, including work in progress, especially people who are between the ages of 50 – 70 years. In addition to those persons who suffer from cardiac ischemia, ischemia this can be due to health problems suffered by the person or as a result of a congenital abnormality.

What are the causes of ventricular fibrillation is?

There are several reasons that can lead to ventricular fibrillation, and the most important of these reasons we mention:


Can occur the case of hypoxia as a result of a number of factors, including:

  • Coronary artery disease.
  • Cardiac ischemia.
  • Inflammation of the heart muscle.
  • Metabolic acidosis.
  • Lack of potassium in the blood.
  • Increased potassium in the blood.
  • A lack of magnesium in the blood.
  • Accidents.
  • Surgeries conducted on heart.

Corporate exposure electrical

  • Alternating current is between 20 – 150 Milli-amp.
  • Constant current between 80 – 600 Milli amp.

Treatments and drugs

The treatment of certain health conditions or use certain types of medications can lead to ventricular fibrillation. Including:

Gas poisoning of

Such as poisoning gas carbon monoxide CO.

Drug poisoning

This may occur as a result of drug abuse such as cocaine.

As we have noted, the causes of ventricular fibrillation are many and varied and each has certain characteristics, so the dealing with those reasons can’t be explained in one article, we will limit ourselves to explain and clarify methods of diagnosis and treatment of some of these causes such as hypoxia and electrolytes and use some types of drugs and exposure to companies electric.

All these reasons lead to the occurrence of an electrical fault in the membranes of the heart muscle, in the normal case, there will be a balance in the ions within the membranes of heart cells, such as ions of calcium, potassium, magnesium, etc., and this balance makes the process of deflation is natural, and therefore the heart works effectively, but in the event of a bug where, most of the cells of the heart will not be able to work normally and thus will reduce the unbalanced and unproductive.

Finally it is important to note a very important topic, which is that some people proper can suffer from ventricular fibrillation, despite the lack of reasons for this, you know this case as the “ventricular fibrillation of unknown cause”, and most of the cases these sudden and not preceded by any symptoms pointing to it.

Symptoms of ventricular fibrillation

Usually the ventricular fibrillation is accompanied by a range of symptoms that are generally associated with each other, among these the most common symptoms in most patients:

  • Shortness of breath.
  • Loss of consciousness.
  • The feeling of pain in the chest.
  • Tachycardia.
  • A defect in blood circulation.
  • General feeling of tired and exhaustion.
  • Blue in skin color.

Because the case of ventricular fibrillation is a serious condition that can lead to bad consequences too, should be on all people understand the symptoms possible and its in time, this is the most important factor that helps save the lives of people who have to shake, ventricular.

Diagnostic methods

In most cases, patients come to the emergency rooms in hospitals and they are suffering from serious cases include irregular heartbeat or a severe abnormality in the blood circulation, therefore, do not have doctors and paramedics adequate time to conduct a full diagnosis, but doctors can say they make a clinical diagnosis of perceiving the injury to the patient to shake the ventricle as a result of his myocardial infarction in early.

The following are some diagnostic tests that can be done:

  • ECG.
  • Echocardiography.
  • Imaging chest X-ray.
  • Coronary angiography.

In most cases, cardiac imaging, electroplating is the method of diagnosis most effective which is required by physicians to assess the electrical activity of the heart, and in the case of injury to the patient to shake the ventricles, the ECG will appear faulty wiggle irregular, this means that a person may suffer one day from the stop in the work of the heart.

Echocardiography helps in the study and evaluation of the ultrasound emanating from the heart, this diagnostic allows to assess the work of all sections of the heart including the atria and ventricles, valves, and allows the identification of whether there are any abnormalities of the heart attack suffered by the person or abnormalities in the form of valves or their operation.

X-ray imaging to be extremely useful in order to assess the degree of understanding of the work of the heart and lungs and determine if the person will be an exhibition of injury that occur as a result of ventricular fibrillation.

Coronary angiography is a surgical procedure done through a catheter, during which the tube is inserted with a camera to see inside the coronary arteries and to determine whether they suffer from any blockage of the training to treat this problem in time, this catheter can help to open coronary arteries clogged thus preventing the occurrence of ventricular fibrillation, a surgical procedure is a routine that can be done in a doctor’s office or hospital under local anesthesia and there is no little danger to the patient as a result of this procedure, the patient can go home immediately after the hours of the catheterization procedure.

Treatment of ventricular fibrillation

It is very important to intervene quickly and in a timely manner in order to treat ventricular fibrillation and to avoid any problem or triggered can result from that, and in case of person suffering from cardiac arrest it would not be in front of the paramedics and the same more than a few minutes to save his life.

Treatment methods are many and varied, the following are the main treatments available:

Calendar the work of the heart or defibrillation

In this procedure, a doctor will use special medical tools to avoid electrical charges and restore the balance in a heartbeat, this can be done by placing two electrodes on the chest of the patient, and when the device determine the direction of ventricular fibrillation, which helps to do the work and think effectively, and thus, the device automatically treating the problem, this procedure can be done treatment by non-specialists under the supervision of a specialist.

Cardiopulmonary resuscitation CPR

In the case of an emergency, when there is no possibility to assess the work of the heart or removal of the defibrillator, there will be a need for cardiopulmonary resuscitation CPR, this procedure is from the first aid necessary to save the patient’s life, and anyone even non doctors do, the main objective is to ensure the continuation of pumping blood to the lungs, brain and other vital organs in the body, and through the introduction of oxygen through the patient’s mouth and massage and squeeze the area of the chest to stimulate heart muscle pumping and mind.

Use of these medications is usually in conjunction with the previous treatments that we have mentioned above, it helps in organizing the work of the heart and the contraction of muscle fibers in it which makes it works naturally, and this allows the patient to live a normal life without feeling the symptoms, types of the counter medications amiodarone milligram of EPI.

In most cases, be the causes that lead to the occurrence of atrial fibrillation of the important factors is to determine the possibility of success of the treatment, for example, if the injured person is atrial fibrillation suffer from problems or diseases of the heart, the other, it may complicate the situation and makes the treatment process harder and requires a much longer time.

Important warning

As we have said several times in this article, believes early diagnosis and medical intervention in time of the best way to help save lives and prevent any damage can be caused to the members of the body as a result of lack of oxygen supply to it, as early intervention reduces the chances of cardiac arrest effectively.
