Final answer:
Supraventricular tachycardia are a group of arrhythmias that arise in the ventricles and can be diagnosed through an electrocardiogram.
Step-by-step explanation:
Supraventricular tachycardia (SVT) refers to a group of abnormal heart rhythms that originate above the ventricles, typically in the atria. This condition causes the heart to beat significantly faster than normal, often above 150 beats per minute. Common types of SVT include atrial fibrillation, atrial flutter, and paroxysmal supraventricular tachycardia.
SVT occurs due to disruptions in the heart's electrical conduction system, which coordinates the contraction and relaxation of the heart muscle. The exact cause of SVT can vary, but it may be related to certain medications, heart muscle abnormalities, or other underlying medical conditions.
Diagnosis of SVT typically involves an electrocardiogram (ECG) and a Holter monitor, which records the heart's electrical activity over a period of time. Treatment options for SVT include medication, lifestyle changes, and in some cases, medical procedures or surgery.
Therefore supraventricular tachycardia (SVT) is a group of abnormal heart rhythms that cause the heart to beat faster than normal. It originates above the ventricles and can be diagnosed through an electrocardiogram. Treatment options include medications and medical procedures.
