What arrhythmia causes tachycardia?

Sinus tachycardia — often the body’s normal response to situations such as stress, anxiety or distress; can be caused by conditions such as anemia, low blood pressure or thyroid disease. Atrial fibrillation (AFib or AF) — irregular heartbeat associated with heart disease, overactive thyroid or alcoholism.

Does ventricular fibrillation cause tachycardia?

Before a ventricular fibrillation episode, you may have signs and symptoms of an abnormally fast or erratic heartbeat (arrhythmia). These warning signs may include: Chest pain. Very fast heartbeat (tachycardia)

What is the difference between tachycardia and arrhythmia?

Arrhythmias are abnormal rhythms of your heartbeat (watch the video). This means that your heart may beat too slowly (bradycardia), too fast (tachycardia), or in an irregular pattern. These abnormal rhythms can occur when the electrical impulses coming from your heart don’t fire as they normally should.

What are the four main types of arrhythmias?

The main types of arrhythmia are bradyarrhythmias; premature, or extra, beats; supraventricular arrhythmias; and ventricular arrhythmias. To understand arrhythmia, it helps to understand how your heart’s electrical system works.

What is the difference between tachycardia and AFib?

Atrial fibrillation is another type of atrial tachycardia that is closely related to atrial flutter. However, the arrhythmia that occurs in AFib is much more chaotic and results in a fast and usually very irregular heart rhythm or a atypical and irregular ventricular rate that can effect heart health.

What happens if tachycardia is left untreated?

But if left untreated, tachycardia can disrupt normal heart function and lead to serious complications, including: Heart failure. Stroke. Sudden cardiac arrest or death.

What is the most common arrhythmia?

Atrial fibrillation, often called AFib or AF, is the most common type of treated heart arrhythmia.
