What are the two types of cardiac arrhythmias?
Arrhythmias are generally divided into two categories: ventricular and supraventricular. Ventricular arrhythmias occur in the lower chambers of the heart, called the ventricles. Supraventricular arrhythmias occur in the area above the ventricles, usually in the upper chambers of the heart, called the atria.
How many cardiac arrhythmias are there?
There are two types of ventricular arrhythmias, which are abnormal heartbeats in the lower chambers of the heart (called ventricles). The first type, ventricular tachycardia, is a fast heart rhythm that can cause dizziness, palpitations, and fainting.
What is the difference between atrial fibrillation and arrhythmia?
Atrial fibrillation (AF) is a form of arrhythmia, or irregular heartbeat, in which the atria (the two small upper chambers of the heart) quiver instead of beating effectively. It is one of the most common forms of cardiac arrhythmia, affecting 0.4% of the general population and 5 to 10% of persons over 65 years of age.
What is VF and VT?
Pulseless ventricular tachycardia (VT) and Ventricular fibrillation (VF) are life-threatening cardiac rhythms that result in ineffective ventricular contractions. The ventricular motion of VF is not synchronized with atrial contractions.
Is tachycardia and arrhythmia the same?
An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia.
What is the difference in tachycardia and arrhythmia?
What is tachycardia arrhythmia? Tachycardia arrhythmia, also referred to as tachycardia, is an abnormally fast heartbeat of more than 100 beats a minute. If left untreated, tachycardia can cause serious complications, including blood clots, heart failure, frequent fainting spells or sudden death.
Which is worse VT or VF?
The outlook for VT is slightly better than VF and some ventricular tachyarrhythmias (fast abnormal heart rates) are surprisingly well tolerated.
