Tests that may be done to evaluate the heart and diagnose supraventricular tachycardia (SVT) include: Electrocardiogram (ECG or EKG). An ECG records the electrical activity of the heart. An ECG measures the timing and duration of each electrical phase in the heartbeat. It can show how fast or slow the heart is beating. Holter monitor. This portable ECG device can be worn for a day or more to record the heart's activity during daily activities. Event recorder. This wearable ECG device is used to detect infrequent arrhythmias. You press a button when symptoms occur. An event recorder is typically worn for up to 30 days or until you have an arrhythmia or symptoms. Echocardiogram. Sound waves are used to create images of the heart in motion. An echocardiogram can provide details about the heart and heart valves. Implantable loop recorder. This device detects irregular heart rhythms and is implanted under the skin in the chest area. Other tests that may be done include: Exercise stress test. Supraventricular tachycardia may be triggered or worsened by stress or exercise. During a stress test, you typically exercise on a treadmill or stationary bicycle while your heart activity is monitored. If you can't exercise and your provider thinks heart disease may be causing your arrhythmia, you may receive a drug during the test to stimulate the heart in a way that's similar to exercise. Tilt table test. Your health care provider may recommend this test if you've had fainting spells. Your heart rate and blood pressure are monitored as you lie flat on a table. The table is then tilted as if you were standing up. Your provider observes how your heart and the nervous system that controls it respond to the change in angle. Electrophysiological (EP) study. One or more thin, flexible tubes (catheters) are guided through a blood vessel, usually in the groin, to various spots in the heart. Sensors on the tips of the catheters record the heart's electrical patterns. An EP study allows a health care provider to see how electrical signals spread through the heart during each heartbeat.

医生可能会问您很多问题。请做好回答这些问题的准备,这样有利于更好地安排时间,去详细了解您所关注的任何方面。医生可能提出以下问题: 您第一次出现症状是在什么时候? 症状是持续存在,还是时有时无? 症状有多严重? 是否有任何因素似乎能令您的症状好转? 有没有什么因素似乎会加重您的症状? 您是否有异常心律的家族史? 来自妙佑医疗国际员工 在 Mayo Clinic 治疗 申请 Mayo Clinic 预约 症状与病因医生与科室 Aug. 29, 2022 打印 显示参考文献 Brugada J, et al. 2019 ESC Guidelines for the management of patients with supraventricular tachycardia: The Task Force for the Management of Patients with Supraventricular Tachycardia of The European Society of Cardiology (ESC).
