Vagal maneuvers, such as the Valsalva maneuver, are often used as the initial treatment. [4] If not effective and the person has a normal blood pressure the medication adenosine may be tried. [4] If adenosine is not effective a calcium channel blocker or beta blocker may be used. [4] Otherwise synchronized cardioversion is the treatment. [4]
Signs and symptoms can arise suddenly and may resolve without treatment. Stress, exercise, and emotion can all result in a normal or physiological increase in heart rate, but they can precipitate SVT in rare cases. Episodes can last from a few minutes to one or two days. They sometimes persist until treated.
The main symptom of AVNRT is the sudden development of rapid regular palpitations. [1] These palpitations may be associated with a fluttering sensation in the neck, caused by near-simultaneous contraction of the atria and ventricles against a closed tricuspid valve leading to the pressure or atrial contraction being transmitted backwards into the venous system. [2]
WPW syndrome may be monitored or treated with either medications or an ablation (destroying the tissues) such as with radiofrequency catheter ablation. [4] It affects between 0.1 and 0.3% in the population. [1] The risk of death in those without symptoms is about 0.5% per year in children and 0.1% per year in adults. [5]
Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome [4] [5] Other presenting signs or ...

The cause of this condition is not accurately known, though it is probably of nervous origin and can be aggravated by physical wear and tear. The symptoms are sometimes very alarming but it is not considered in itself dangerous. [4] It has an increased risk of developing in WPW syndrome and LGL syndrome. [5]
Multifocal (or multiform) atrial tachycardia (MAT) is an abnormal heart rhythm, [2] specifically a type of supraventricular tachycardia, that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease (COPD).
