To reduce the chances of developing supraventricular tachycardia, avoid smoking, limit alcohol intake and stay away from illicit drugs. A paroxysmal supraventricular tachycardia is a condition in which the heart rate becomes rapid from time to time, notes MedlinePlus.
Individuals with supraventricular tachycardia are likely to experience a tightness or fullness in the throat. They may sometimes feel a fast or fluttering feeling in the chest. Other symptoms associated with this condition include shortness of breath, increased pulse rate, passing out, dizziness, body weakness and excessive passing of urine.
Nicotine greatly increases the chances of this condition, which is why it is important to avoid products with this substance. Excessive consumption of alcohol and certain drugs, including decongestants, should be shunned. Doctors commonly inquire about the patient's history in the initial stages of diagnosis. Other tests used in diagnosis include blood tests, X-rays and a physical exam.
Treatment of the condition may involve cardioversion or administration of medication through the veins. Doctors may give advice on how to find relief during an episode of supraventricular tachycardia. Medications such as adenosine, beta-blockers and calcium channel blockers can be an effective way to deal with the condition. In certain cases, doctors may have to carry out a surgical procedure, notes WebMD.
