There are several types of tachycardia and common types include:
Sinus tachycardia – Sinus tachycardia refers to heartbeats that are faster than usual but with a steady rhythm. It can be caused by mental or physical stress, fever, the use of certain medications, and certain health conditions.
Atrial or supraventricular tachycardia – This type of tachycardia refers to an accelerated heart rate that occurs in the upper chambers of the heart. It leads to episodes of heart palpitations that begin and end abruptly.
Atrial fibrillation – The most common type of tachycardia, A-fib is associated with irregular electrical signals in the upper chambers of the heart (atria), causing the heart to beat faster.
Atrial flutter – It is similar to A-fib, but with more organized heart rhythms.
Ventricular tachycardia – This type starts in the heart’s lower chambers (ventricles) and is associated with abnormal heart signals, caused by cardiovascular problems and the use of certain medications.
Ventricular Fibrillation – Ventricular fibrillation refers to chaotic electrical signals that cause the ventricles to quiver. It is a serious heart condition that can lead to complications and death if the heart rhythm is not restored.
