Supraventricular tachycardia (SVT) is a type of irregular heartbeat, also called an arrhythmia. It's a very fast or erratic heartbeat that affects the heart's upper chambers. SVTalso is called paroxysmal supraventricular tachycardia. The typical heart beats about 60 to 100 times a minute. During SVT, the heart beats about 150 to 220 times a minute....
The main symptom of supraventricular tachycardia (SVT) is a very fast heartbeat that may last for a few minutes to a few days. The heart beats 100 or more times a minute. Usually during SVT, the heart beats 150 to 220 times a minute. The fast heartbeat may come and go suddenly. Symptoms of supraventricular tachycardia may include: 1. Pounding or fl...
Supraventricular tachycardia (SVT) is caused by faulty signaling in the heart. Electrical signals in the heart control the heartbeat. In SVT, a change in heart signaling causes the heartbeat to start too early in the heart's upper chambers. When this happens, the heartbeat speeds up. The heart can't fill with blood properly. Symptoms such as lighth...
Supraventricular tachycardia (SVT) is the most common type of arrhythmia in infants and children. It also tends to occur more often in women, particularly during pregnancy. Health conditions or treatments that may increase the risk of supraventricular tachycardia include: 1. Coronary artery disease, heart valve disease and other heart diseases. 2. ...
When the heart beats too fast, it may not send enough blood to the body. As a result, the organs and tissues may not get enough oxygen. Over time, untreated and frequent attacks of supraventricular tachycardia (SVT) may weaken the heart and lead to heart failure. This is especially true in people who also have other medical conditions. A severe att...
The same lifestyle changes used to manage supraventricular tachycardia (SVT) also may help prevent it. Try these tips. 1. Follow a heart-healthy lifestyle.Eat a nutritious diet, don't smoke, get regular exercise and manage stress. 2. Don't use a lot of caffeine. Avoid large amounts of caffeine. For most people with supraventricular tachycardia, mod...

Nov 10, 2022 · This article is a guide for interpreting abnormal Supraventricular Tachycardia EKGs, including qualifying criteria and a sample EKG rhythnm strip. Supraventricular tachycardia (SVT) is a rapid heart rhythm originating at or above the AV node.
Aug 7, 2023 · The first test to evaluate for SVT is to obtain an ECG. ECG characteristic includes a narrow complex, regular tachycardia with a rate of approximately 180 to 220 beats per minute. P waves are not detectable. If P waves are detectable, consider sinus tachycardia or atrial fibrillation or flutter as a potential etiology.
