A normal resting heart rate is 60 to 100 beats per minute. A resting heart rate of more than 100 beats per minute is defined as a tachycardia. During an episode of SVT, the heart beats about 150 to 220 times per minute. [9] Specific treatment depends on the type of SVT [5] and can include medications, medical procedures, or surgery. [5]
The main risk of this procedure is accidental damage to the AV node. This occurs more frequently when treating JET than other forms of supraventricular tachycardia, requiring treatment with a pacemaker in 5-10% of ablations for JET. [7] The risk is lower if the tissue is frozen rather than heated. [7]
The congenital heart block (CHB) is the heart block that is diagnosed in fetus or within the first 28 days after birth [1] [4] (neonatal period), some studies also include the diagnosis during early childhood to the definition of CHB. [5]
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents.
Procainamide (PCA) is a medication of the antiarrhythmic class used for the treatment of cardiac arrhythmias. It is a sodium channel blocker of cardiomyocytes; thus it is classified by the Vaughan Williams classification system as class Ia. In addition to blocking the I Na current, it inhibits the I Kr rectifier K+ current. [1]
If atrial fibrillation with pre-excitation occurs, treatment options include procainamide, flecainide, propafenone, dofetilide, and ibutilide, since these medications slow conduction in the accessory pathway causing the tachycardia and should be administered before considering electrical cardioversion.
AV nodal reentrant tachycardia is the most common regular supraventricular tachycardia. It is more common in women than men (approximately 75% of cases occur in females). The main symptom is palpitations. Treatment may be with specific physical maneuvers, medications, or, rarely, synchronized cardioversion.
Otherwise synchronized cardioversion is the treatment. [4] Future episodes can be prevented by catheter ablation. [3] About 2.3 per 1000 people have paroxysmal supraventricular tachycardia. [5] Problems typically begin in those 12 to 45 years old. [3] [5] Women are more often affected than men. [3]
