To diagnose supraventricular tachycardia, your doctor will review your symptoms and your medical history and conduct a physical examination. Your doctor may ask about â or test for â conditions that may trigger your SVT, such as heart disease or a problem with your thyroid gland. Your doctor may also perform heart-monitoring tests specific to arrhythmia. These may include:
If your doctor doesn't find an arrhythmia during those tests, he or she may try to trigger your arrhythmia with other tests, which may include:
Electrophysiological testing and mapping. In this test, doctors thread thin tubes (catheters) tipped with electrodes through your blood vessels to a variety of spots within your heart. Once in place, the electrodes can map the spread of electrical impulses through your heart.
In addition, your cardiologist can use the electrodes to stimulate your heart to beat at rates that may trigger â or halt â an arrhythmia. This allows your doctor to see the location of the arrhythmia and what may be causing it.
Research is ongoing regarding the effectiveness of several forms of complementary and alternative medical therapies for supraventricular tachycardia.
Some types of complementary and alternative therapies may be helpful to reduce stress, such as:
Some studies have shown that acupuncture may help reduce irregular heart rates in certain arrhythmias, but further research is needed.
The role of omega-3 fatty acids, a nutrient found mostly in fish, in the prevention and treatment of arrhythmias isn't yet clear. But it appears as though this substance may be helpful in preventing and treating some arrhythmias.
Your doctor may suggest that, in addition to other treatments, you make lifestyle changes that will keep your heart as healthy as possible.
These lifestyle changes may include:
