Wide complex tachycardia: differentiating ventricular tachycardia from supraventricular tachycardia
Heart, 2021### Learning objectives A wide QRS complex tachycardia (WCT) is defined as a tachycardia with QRS duration of >120 ms. Distinguishing between the different potential causes of a WCT can have important implications, particularly in terms of determining the urgency of treatment, deciding between different antiarrhythmic drugs and risk stratification for

Apropos “Tachycardia Begets Tachycardia”
Pacing and Clinical Electrophysiology, 2005It has been shown that a tachycardia can facilitate the induction of the same (“atrial fibrillation begets atrial fibrillation”) or a different tachycardia. This may also apply for pacemaker‐mediated tachycardia as the present case documents.

This paper presents two cases of neonatal paroxysmal atrial tachycardia originating in the same country area, and in fact, presenting to the same general practitioner within a month of each other. Both cases were complicated by cardiac failure, and various forms of treatment were employed with variable success.

The term paroxysmal supraventricular tachycardia encompasses a heterogeneous group of arrhythmias with different electrophysiologic characteristics. Knowledge of the mechanism of each supraventricular tachycardia is important in determining management in the office, at the bedside, and in the electrophysiology laboratory.

Supraventricular tachycardias (SVT) comprise those tachycardias that originate above the bifurcation of the bundle of His. They can be classified broadly as AV node dependent and AV node independent. The mechanism and clinical manifestation of SVTs, which is essential to their correct diagnosis, is reviewed.

Twenty-one patients were studied to investigate whether cardiac acceleration above control values occurred after cessation of enhanced vagal tone (postvagal tachycardia), and to determine the effects of selective autonomic blockade on postvagal tachycardia. Patients had neither sinus arrhythmia nor sinus nodal dysfunction.
