Deshpande S, Supraventricular tachycardia. Pacing Clin Electrophysiol. Belardinelli L, [4] Blood tests may be done to rule out specific underlying causes such as hyperthyroidism or electrolyte abnormalities. AVNRT and AVRT are electrical aberrancies that occur mainly as a result of reentry. et al. 6. Table 1 describes ECG findings for common types of SVT.3–6. 1988;62(6):10D–15D.

Morton JB, Cheng J, Treatment of SVT can be divided into short-term or urgent management and long-term management. et al.


Mitrani RD, In the large majority of cases, SVT can be cured once and for all by an ablation procedure. Most SVTs are caused by extra electrical pathways, and usually, those extra pathways can be accurately localized by electrical mapping during an electrophysiology study and then ablated. Short-term or urgent management of SVT can be separated into pharmacologic and nonpharmacologic strategies.

If your SVT does not stop within 15 to 30 minutes, or if your symptoms are severe, you should go to the emergency room. Download the Strack & Van Til app in the Google Play Store or (iTunes) App Store. Johnson-Liddon V,      Print.

Ischemia or any sudden death suggest supraventricular tachycardia. (ECG = electrocardiography; IV = intravenous; VT = ventricular tachycardia.). 22. Don't miss a single issue.

Patients with infrequent SVT episodes may only need pharmacotherapy on an intermittent basis, or what has been described as the “pill-in-the-pocket” approach.36 Those experiencing SVT not more than a few times per year, but with episodes lasting one hour or longer, may be treated using this approach.
Most types of SVT have narrow QRS complexes. It is highly effective for the termination of nodal-dependent SVT and is the first-line drug for acute conversion of narrow complex SVT.23 Adenosine has the advantage of temporarily slowing the rate enough to determine the underlying focus of the rhythm (i.e., ventricular or supraventricular).

Plumb VJ. Kay GN, The primary treatment goal for any SVT is its cessation, especially in patients who are at risk hemodynamically and cannot tolerate prolonged tachyarrhythmias. Boyle M. Miles W, Porter MJ,

Vagal maneuvers are an effective first-line treatment option for SVT in younger patients who are hemodynamically stable; they can also be diagnostic for nodal-dependent SVT.
