2 Approximately one-half of patients with SVT are age 45 to 64 years. Junctional tachycardia is a type of nonreentrant SVT. 6 This arrhythmia arises from the AV junction. Sinus tachycardia is ...

Therapies targeting this dysregulation have been actually developed. Figure 3. Twelve-lead ECG tracing during stress test shows the typical aspect of bidirectional ventricular tachycardia ...

The rate of these tachycardias usually exceeds 70 bpm. Figure 4 illustrates an example of nonparoxysmal junctional tachycardia. Note the gradual onset of the junctional mechanism as the sinus ...

Ventricular tachycardia is an abnormally fast heart beat (with three or more consecutive heart beats at least 100 beats per minute) that originates from one of the ventricles in the heart.

The high incidence of atrial arrhythmias is mostly due to AF. However, sinus tachycardia, another atrial arrhythmia, is a common physiologic response to stressors such as pain, fever, exercise ...
