There are two arrhythmias that originate in the ventricles (lower chambers of the heart) and are more dangerous than atrial fibrillation. Fortunately, they are less frequent. In the case of ventricular tachycardia, the ventricles beat very fast speeds (well above 100), which does not allow to fill with blood and so the heart can not distribute it to the body and oxygenate organs can and tissues, which is dangerous if it lasts a long time. It can cause palpitations, dizziness, weakness, low blood pressure and fainting. You can convert ventricular fibrillation is an arrhythmia worse.
In ventricular fibrillation, as in the case of atrial fibrillation, the ventricles quiver rapidly and irregularly and also fail to pump blood efficiently and the result is the same as in ventricular tachycardia but much more rapid and severe. If not treated quickly because it ends with fatal cardiac arrest.
Arrhythmias can scare the person who suffers, but in many cases and especially in young people with no history of heart disease, not a serious hazard and can be treated with medication. Supraventricular arrhythmias are common in middle-aged and elderly. Usually as you get older increase the odds of suffering from them, especially atrial fibrillation. Many appear temporarily in response to emotions or normal activities, but arrhythmias can be dangerous and that’s always important when you suspect you may have an arrhythmia that evaluate a cardiologist to determine if treatment is needed.
This is a large topic that deserves explained in detail, so that you can better understand the information, we will continue to explain other types of arrhythmia in a later article. If this topic interests you, stay tuned so you can identify them and therefore do not panic the next time you lost your heart over.
