Mickelsen S, The success rate of the valsalva maneuver alone is documented at 5 – 20%. Szénási G, Adapted from Delacrétaz E. Clinical practice. Rodriguez LM, Most patients with AVNRT do not have structural heart disease; the group most often affected is young, healthy women.8 However, some patients do have underlying heart disease, such as pericarditis, previous myocardial infarction, or mitral valve prolapse.9 The coexistence of slow and fast pathways in atrioventricular nodal tissue is the basis of aberrant substrate for reentrant tachyarrhythmias.10, The second most common type of SVT is AVRT. Long RP tachycardias result when atrial activity precedes the QRS complex. Boyle M. This article focuses on the most common types of paroxysmal SVT: atrioventricular nodal reentrant tachycardia (AVNRT), atrioventricular reciprocating tachycardia (AVRT), and atrial tachycardia (AT). Younger patients who are otherwise healthy usually have a normal examination, with tachycardia (if present on examination) being the only physical finding. Kusumoto FM. Johnson-Liddon V, Typically, SVT occurs in discrete episodes, which most often begins very suddenly and stop equally suddenly. et al. Podczeck A, RANDALL A.

Because of shorter procedure duration, lessened fluoroscopic exposure, and increased knowledge in this area of cardiology, catheter ablation is becoming the first-line treatment option for all patients with SVT, not just those with symptomatic arrhythmias refractory to suppressive drug therapy or those who prefer a drug-free lifestyle.

Mortality in patients treated with flecainide and encainide for supraventricular arrhythmias. Less commonly, increased automaticity or triggered activity can be the mechanism and usually results in a narrow complex tachycardia. Brugada criteria are sensitive and specific in helping distinguish between SVT with aberrancy and ventricular tachycardia. Mes classes. Byrd RC, Deal BJ, 2001;65(5):367–370. Supraventricular tachycardia does not include those tachycardia rhythms that originate from the ventricles (ventricular tachycardias) such as ventricular tachycardia or ventricular fibrillation. N Engl J Med. Fuster V, Paroxysmal supraventricular tachycardia in the general population. N Engl J Med. 5. Nom. (B) In atrioventricular reciprocating tachycardia, there is typically a short RP interval, with the timing and morphology of the P wave dependent on the site and conduction velocity of the accessory pathway. After this, the area is bombarded by radio frequency waves from the catheter changing the SVT. Linden J, Am J Cardiol. Nom d'utilisateur. 30. Epstein AE, Ann Intern Med. Kistler PM, 16. Treatment of SVT can be divided into short-term or urgent management and long-term management. No adverse effects occurred, and the likelihood of making a correct diagnosis of SVT or ventricular tachycardia increased.35, The long-term management of SVT is based on the SVT type; frequency and intensity of the episodes; overall impact on the quality of life of the patient; and risks of the therapy chosen.19  Discussion of these issues with the patient will help determine the optimal treatment strategy. Breithardt G. Haqqani HM, Ohara T, Comparison of the efficacy and safety of esmolol, a short-acting beta blocker, with placebo in the treatment of supraventricular tachyarrhythmias.

Verapamil, a negative inotrope, can result in relative bradycardia and vasodilation; care must be used if patients have a significant decrease in cardiac output.27 Neither digoxin nor a calcium channel blocker should be used in patients with Wolff-Parkinson-White syndrome or wide complex tachycardia, because these agents may enhance conduction down the accessory pathway, predisposing the patient to ventricular fibrillation.28 If the SVT persists, addition of a beta blocker will often result in its termination.29. The cardiac effects of adenosine. 2009;37(9):2512–2518. et al. Symptoms of SVT depend on a number of factors, including patient age, presence of comorbid heart and lung disease, and duration of SVT episodes. Electrocardiogram of a narrow complex tachycardia with a 1:1 atrioventricular association in a 16-yearold girl with tachypalpitations. Tischenko A, Patients may also be asymptomatic or minimally symptomatic, potentially delaying diagnosis. Glatter KA, Delacrétaz E. Role of radiofrequency ablation in the management of supraventricular arrhythmias: experience in 760 consecutive patients. Table 6 shows recommended agents for short-term management of SVT.22 Which agent is selected after use of vagal maneuvers and adenosine depends on patient factors, such as contraindications (any comorbid conditions or allergies), hemodynamic stability, or presence of a wide QRS complex. Generally, these agents should be managed by a cardiologist. Clinical practice. Adenosine may be used as a diagnostic or therapeutic agent in patients with undifferentiated wide complex tachycardia. For some patients Atenolol works very well, and there do not appear to be any long-term side effects of beta-blockers that differ from the short-term ones.

If Wolff-Parkinson-White syndrome is present, expedient referral to a cardiologist is warranted because ablation is a potentially curative option. Chest discomfort or pressure; dyspnea; fatigue; lightheadedness or dizziness; palpitations (including possible pulsations in the neck), Chest pain (more severe than discomfort); diaphoresis; nausea; presyncope or syncope, Sudden death (may occur with Wolff-Parkinson-White syndrome), The history may reveal the likely etiology underlying the SVT (Table 3).

Akhtar M, AT = atrial tachycardia; AVNRT = atrioventricular nodal reentrant tachycardia; AVRT = atrioventricular reciprocating tachycardia; bpm = beats per minute; SVT = supraventricular tachycardia. Brugada P. Nonpharmacologic management typically uses maneuvers that increase vagal tone to decrease heart rate. 22. Mont L, Brady WJ, 28. Duray G, et al. Cheng CH, Pritchett EL, Clinical series of radiofrequency catheter ablation of accessory pathways have been published with excellent overall results.38 Experienced electrophysiology laboratories routinely achieve success rates of 95 percent in the ablation of accessory pathways, with recurrence rates of less than 5 percent.39 With improved knowledge of atrioventricular nodal anatomy and the advent of cryotherapy ablation, the current rate of symptomatic heart block is 0.5 to 1 percent.40, Because of its curative results and low percentages of severe adverse effects, and because the field is evolving so rapidly, there are few studies directly comparing catheter ablation with drug therapy in patients with SVT (with the exception of atrial fibrillation).
