Multifocal atrial tachycardia (MAT) is a relatively infrequent arrhythmia, with a prevalence rate of 0.05-0.32% in patients who are hospitalized. Most patients with ventricular tachycardia have another heart problem, such as coronary artery disease, high blood pressure, an enlarged heart (cardiomyopathy) or heart valve disease. Summary. It's a broad term that includes many forms of heart rhythm problems (heart arrhythmias) that originate above the ventricles (supraventricular) in the atria or AV node. Supraventricular tachycardias are related disorders in which the elevation in heart rate is driven by pathophysiology in the atria. SVT can cause the heart to beat very rapidly or erratically. Postural orthostatic tachycardia syndrome (POTS) is a condition that affects circulation (blood flow). Identify baseline fetal heart rate and presence of variability, both long-term and beat-to-beat (short-term). Define supraventricular tachycardia. Catecholaminergic polymorphic ventricular tachycardia is defined as ventricular tachycardia that develops in relation with genetic causes and is related with catecholamine release, which is triggered by exertion and emotional stress in the absence of structural cardiac disease (1, 2). Ventricular tachycardia: An abnormal heart rhythm that is rapid and regular and that originates from an area of the lower chamber of the heart. Overview. It is predominantly observed in males and in older patients—in particular, elderly patients with multiple medical problems.

Paroxysmal means that the episode of arrhythmia begins and ends abruptly. Long-term treatment for people who have repeat episodes of PSVT, or who also have heart disease, may include: Cardiac ablation, a procedure used to destroy small areas in your heart that may be causing the rapid heartbeat (currently the treatment of choice for most PSVTs) Daily medicines to … Simply slowing the heart rate could cause more harm if your rapid heartbeat is a symptom of a more serious or long-term problem. Paroxysmal atrial tachycardia is a type of arrhythmia, or irregular heartbeat. If not treated, other forms of tachycardia can lead to: stroke; heart failure; cardiac arrest There are four main types: atrial fibrillation, paroxysmal supraventricular tachycardia (PSVT), atrial flutter, and Wolff–Parkinson–White syndrome. The word tachycardia came to English from New Latin as a neoclassical compound built from the combining forms tachy-+ -cardia, which are from the Greek ταχύς tachys, "quick, rapid" and καρδία, kardia, "heart".
