![]() Ventricular fibrillation or v-fib is the most common and deadly irregular heart rhythm (arrhythmia). It occurs due to a problem with the electrical impulses firing on their own in the ventricle (lower chamber of the heart.) Ventricular tachycardia (VT or V-tach) is an irregular heart rhythm (arrhythmia). Your heart rate is controlled by electrical impulses that trigger each contraction and set the heart’s rhythm. It is similar to atrial fibrillation and is often also managed the same. This happens when an electrical short circuit in the atrium makes a loop of cells to generate a high regular atrial rhythm that leads to a fast heartbeat rate in the upper chamber. It can make your heart contract in an uncoordinated fashion rather than an organized atrial contraction. It causes the ventricles to be bombarded by 100’s of electrical signals which are too rapid and irregular. This is a term used when the atria, or the chambers above the ventricle is beating irregularly and very rapidly. SVT may also occur due to an electrical signal without any apparent underlying cause and is referred to as paroxysmal supraventricular tachycardia (PSTV). This may occur as a response to illness, injury, stress, or vigorous physical activity. Supraventricular tachycardia (SVT) is a general term used to describe a rapid heartbeat generated by electrical signals above the ventricle and is caused by adrenaline when the body requires more oxygen. ![]() This is a common type of palpitation that occurs when a fault with your heart’s electrical system causes it to miss a heartbeat or have an extra heartbeat.Ī premature atrial contraction (PAC) is a normal variant that is caused when the SA node prematurely generates a heartbeat before the heart is ready, making you feel as if there is a thump or flop in the chest.Ī premature ventricular contraction ( PVC) is usually caused by an early and extra electrical beat generated in the ventricular muscle cells and makes you feel a thump. Most of the time, palpitation goes unnoticed but an underlying medical condition may cause it. Palpitations are grouped and described based on their frequency (clustered or isolated), their location( (atrium, AV node, or ventricle), and, whether the beats are regular or irregular in rhythm and persistent. There are many variants and types of palpitations, depending on where the electrical impulse is generated in the heart d if that signal can generate a heartbeat.
