Automatic tachycardia
Automatic Tachycardia
Automatic tachycardia (pronunciation: au·to·mat·ic ta·chy·car·di·a) is a type of tachycardia characterized by a rapid heart rate that originates from automatic cells in the heart, rather than from the sinoatrial node (the heart's natural pacemaker).
Etymology
The term "automatic tachycardia" is derived from the Greek words "automatos" (self-acting) and "tachys" (swift), and the Latin word "cardia" (heart).
Overview
Automatic tachycardia is a form of supraventricular tachycardia (SVT), a broad term that includes various conditions that cause an abnormally fast heart rate. These conditions are due to problems with the electrical system of the heart. In automatic tachycardia, the rapid heart rate is caused by cells in the heart that start to fire rapidly. These cells are called automatic cells because they can generate their own electrical impulses, independent of the sinoatrial node.
Symptoms
Symptoms of automatic tachycardia can include palpitations, shortness of breath, chest pain, dizziness, and fainting. These symptoms can be severe and may require immediate medical attention.
Diagnosis
Diagnosis of automatic tachycardia is typically made through an electrocardiogram (ECG), which can detect the abnormal electrical activity in the heart. Other diagnostic tests may include a Holter monitor, event monitor, or stress test.
Treatment
Treatment for automatic tachycardia can include medications, cardioversion, or catheter ablation. The specific treatment will depend on the severity of the condition, the patient's overall health, and the underlying cause of the tachycardia.
