Arrhythmia

Most people who have ventricular fibrillation have an underlying heart disease or have experienced serious trauma. Ventricular tachycardia. This rapid, regular heart rate starts with faulty electrical signals in the lower heart chambers (ventricles).

This arrhythmia is not dangerous in healthy people because it usually has little impact on the heart. But in people with heart problems, such as a heart valve disease, or those who have had a heart attack, it can trigger more dangerous arrhythmias. These can include ventricular tachycardia or ventricular fibrillation.

Ventricular arrhythmias occur when the normal pattern of electrical signals is disrupted , causing the heart to beat too fast. These too-rapid heart rates can prevent the heart from effectively pumping blood to the body.
