VENTRICULAR TACHYCARDIA: Causes, Signs and Treatment!
WHAT IS VENTRICULAR TACHYCARDIA?
Ventricular Tachycardia Definition: Ventricular Tachycardia (“heart rash”) is a heart rate faster than 100 beats/minute and is one of the heart rhythm disorders. The anterior tachycardia has its origin in the heart auricles.
The heart consists of the atria and the ventricles. The excitation occurs in the sinus node, runs through the atria, is transferred to the chambers only by a certain point, the atrioventricular node (AV node) and runs there on certain pre-existing orbits.
WHAT IS THE CAUSE OF VENTRICULAR TACHYCARDIA?
Ventricular Tachycardia Causes: Tachycardia is for the most part caused by an interruption in the ordinary electrical impulses that control our heart’s pumping activity – the rate at which our heart pumps. The accompanying circumstances, conditions, and diseases are conceivable causes:
- A response to specific drugs
- Innate (show during childbirth) electrical pathway irregularities in the heart
- Inherent irregularities of the heart
- Expending excessively liquor
- Utilization of cocaine and some other recreational medications
- Electrolyte irregularity
The coronary illness which brings about poor blood supply and harm to heart tissues, including coronary vascular disease (atherosclerosis), heart valve illness, heart failure, heart muscle illness (cardiomyopathy), tumours, or inflammation.
- Hyperthyroidism (overactive thyroid organ)
- Certain lung illnesses
Once in a while, the restorative group may not recognize the correct reason for the tachycardia.
WHAT ARE THE SYMPTOMS OF VENTRICULAR TACHYCARDIA?
Ventricular Tachycardia Symptoms: All major tachycardias are accompanied by severe heart palpitations and palpitations in the chest or throat, which is called palpitations. In addition, there is often (unintended) polyuria, that is, an increased excretion of urine.
As the rate of filling of the heart chambers with blood shortens with increasing frequency, the brain can become less well supplied with the appearance of dizziness and unconsciousness, which is called syncope. This is particularly the case with slow rhythmic disturbances.
Finally, in the case of rhythmic disturbances, such as dyspnoea, which prevent the normal stroke of the atrium, blood congestion can occur with clot formation (thrombus) in the atrium. In the most unfavourable case, the clot (embolism) dissolves, is swept to the brain and causes a stroke (insult) due to the blockage of an artery.
HOW IS VENTRICULAR TACHYCARDIA DIAGNOSED?
Ventricular Tachycardia Diagnosis: The diagnosis is made by ECG, long-term ECG and possibly an electrophysiological examination (EPU). Sometimes a long-term ECG is not sufficient because the rhythm disturbances occur only sporadically. Then an event recorder (event recorder) can be given to the patient who, for example, records the ECG before and after triggering for a few minutes at the push of a button.
New is the so-called heart mobile phone, a mobile phone, which can derive an ECG independent of the location and send it immediately to the emergency centre. Here, an expert immediately interprets the recording and can analyze the rhythm disturbance.
For the interpretation of the ECG, it should be noted briefly that it is important to analyze the relationship between the P-wave, as an expression of the pre-stimulation and the QRS complex, as an expression of the chamber excitement. Tachycardias with a narrow QRS complex always originate above the heart chambers.
WHAT IS THE TREATMENT FOR VENTRICULAR TACHYCARDIA?
Ventricular Tachycardia Treatment: The very rapid transfer to the heart chambers is dangerous to life in pre-emptive tachycardias, such as, for example, the Vorofflimmern. Drugs (antiarrhythmics), such as beta-blockers, calcium antagonists or digitalis preparations, can be used to transfer only a portion of the excitatory excitations and the chambers can continue to function. Other antiarrhythmic agents are used more cautiously because of their side effects.
A “mechanical” possibility of preventing rapid rhythm disturbances exists in the case of screenings or reentry tachycardias due to the ablation. In this case , an additional path or the natural AV node is rendered non-functional by means of a catheter which is heated by electric current, which leads to immediate healing in the case of success. The ablation is possible in the case of ventricular fibrillation, AV reentrant tachycardia or WPW syndrome.
Slow rhythm disorders are rarely treated with medication – the choice is a heart pacemaker. Only a few, very modern heart pacemakers can also recognize ventricular tachycardia and treat by overstimulation or cardioversion.
