resulting in AVRT. Findings on ECG include the following: a narrow complex tachycardia; and variable findings, depending on the direction of the circuit and location of the accessory conduction ...

The initial differential diagnosis of supraventricular tachycardias should focus on the ventricular response, not on atrial depolarization as observed on the ECG. The first step is to determine ...

Overall, the most common mechanism in this cohort was AVNRT followed by AVRT and atrial tachycardia. What are the different mechanisms of SVT? Understanding the underlying mechanism is useful in ...

The usual presentation of supraventricular tachycardia on electrocardiography (ECG) is as a narrow-QRS-complex tachycardia (a QRS interval of less than 120 msec), but in some cases (less than 10 ...

The first QRS complex is narrow and supraventricular (*). It is followed by a rapid and irregular rhythm with a rate of up to 300 beats/min. The QRS complexes are unusual and show marked ...

Supraventricular tachycardia (SVT ... in Clinical Medicine suggests that the use of 12-lead electrocardiography (ECG) is critical in diagnosing SVT and determining short- and long-term management ...

The key difference is that AVRT is due to an additional pathway that can lead to irregular heart rhythms. An electrocardiogram (ECG) can help doctors differentiate between the two. PSVTs ...

Supraventricular tachycardia (SVT ... If doctors suspect SVT, they will likely order an ECG test. During an ECG, the doctor places sticky electrodes on the chest. The electrodes connect to ...

Atrioventricular reentrant tachycardia (AVRT) is a rhythm problem in your heart that makes it beat too fast. It results from an extra connection between your upper and lower chambers. You might ...
