What are the ventricular arrhythmias?

What are the ventricular arrhythmias?

Ventricular arrhythmias are abnormal heart rhythms that make the lower chambers of your heart twitch instead of pump. This can limit or stop your heart from supplying blood to your body. While some of these arrhythmias are harmless and don’t cause symptoms, some can have serious — or even deadly — effects on your body.

What does VT look like?

The heart beats so fast that it can’t get enough blood to the rest of your body. Symptoms of VT may include: Fast heartbeat or a fluttering feeling in the chest (palpitations) Dizziness.

What is the most common ventricular arrhythmia?

Heart attack is the most common cause of ventricular arrhythmia, but it can also occur during heart surgery or as a result of cardiomyopathy or a genetic heart rhythm disorder, such as long QT syndrome or Brugada syndrome. Ventricular fibrillation can also be caused by recreational drug use, including cocaine.

Why are ventricular arrhythmias so serious?

Ventricular fibrillation is more serious than atrial fibrillation. Ventricular fibrillation frequently results in loss of consciousness and death, because ventricular arrhythmias are more likely to interrupt the pumping of blood, or undermine the heart’s ability to supply the body with oxygen-rich blood.

What triggers ventricular arrhythmias?

Ventricular tachycardia most often occurs when the heart muscle has been damaged and scar tissue creates abnormal electrical pathways in the ventricles. Causes include: Heart attack. Cardiomyopathy or heart failure.

How is ventricular arrhythmia diagnosed?

The most common test used to diagnose ventricular tachycardia is an electrocardiogram (ECG/EKG). An EKG records your heart’s electrical activity. Electrodes (small sticky patches) are placed on your chest and arms to record the heart’s rhythm, and the pattern prints on graph paper.

How can you tell the difference between SVT and VT?

During SVT, the tachycardia originates from the atria or involves the atria in the tachycardia circuit. During VT, cardiac activation originates from the ventricle and atrial activation may or may not be linked to ventricular activation.

What is the difference between VT and SVT?

Tachycardia can be categorized by the location from which it originates in the heart. Two types of tachycardia we commonly treat are: Supraventricular tachycardia (SVT) begins in the upper portion of the heart, usually the atria. Ventricular tachycardia (VT) begins in the heart’s lower chambers, the ventricles.

Can you feel ventricular arrhythmia?

Heart arrhythmias may feel like a fluttering or racing heart and may be harmless. However, some heart arrhythmias may cause bothersome — sometimes even life-threatening — signs and symptoms. However, sometimes it’s normal for a person to have a fast or slow heart rate.

How do you fix ventricular arrhythmia?

Treatment for ventricular tachycardia may include medication, a shock to the heart (cardioversion), catheter procedures or surgery to slow the fast heart rate and reset the heart rhythm.

How is VT treated?

Sometimes ventricular tachycardia can cause the heart to stop (sudden cardiac arrest). Treatment for ventricular tachycardia may include medication, a shock to the heart (cardioversion), catheter procedures or surgery to slow the fast heart rate and reset the heart rhythm.

Which is worse SVT or VT?

The symptoms of VTs are usually more severe, and have a much greater tendency to be fatal. While SVTs are not usually life-threatening, they can cause both emotional and physical problems. It is cause for concern if a patient experiences frequent SVTs or if the episodes are lengthy.
