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]
Effective treatment consequently requires knowledge of how and where the arrhythmia is initiated and its mode of spread. [27] Lifestyle changes, medication and heart procedures may be needed to control or eliminate the rapid heartbeats and related symptoms. [9] SVTs can be categorised by whether the AV node is involved in maintaining the rhythm.
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.

The number of adults without CVD who reported using aspirin was 14.4%, down from 20.6% in 2021. However, when stratified by age, a different picture emerges: for adults 70 and older, 38% are still ...
Verapamil is used for controlling ventricular rate in supraventricular tachycardia (SVT) and migraine headache prevention. [17]Verapamil is also used for the treatment of angina (chronic stable, vasospastic or Prinzmetal variant), unstable angina (crescendo, preinfarction), and for the prevention of paroxysmal supraventricular tachycardia (PSVT).
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).
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 ...
