Acta Obstetricia et Gynecologica Scandinavica, EarlyView.The Swedish fetal heart rate (FHR) classification from 2017 identifies most FHR patterns associated with fetal acidemia as non‐normal, according to fetal blood sampling (FBS) in immediate connection to the ongoing FHR pattern. However, long‐standing FHR patterns with non‐repetitive decelerations of the types severe variable and late warrant increased ...

Radial outer retina reflectivity (RORR) sign in LAMP2‐associated retinopathy
Acta Ophthalmologica, EarlyView.Abstract Purpose To describe the radial outer retina reflectivity (RORR) sign in patients carrying pathogenic variants in the X‐linked lysosome‐associated membrane protein‐2 (LAMP2) gene and to review the histologic characteristics of LAMP2 expression in the human retina.

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.

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.

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

Atrial Tachycardia Facilitating Initiation of Ventricular Tachycardia
Pacing and Clinical Electrophysiology, 1983A 17‐year‐old male was studied because of clinically documented tachycardias showing narrow and wide QRS complexes. He was found to suffer from an atrial and a ventricular tachycardia. It was demonstrated that initiation of ventricular tachycardia occurred on reaching a critical ventricular rate during atrial tachycardia.

The Supraventricular Tachycardias
Annual Review of Medicine, 1988Most supraventricular tachycardias can be diagnosed confidently using the standard 12-lead electrocardiogram, the more so if such a tracing in sinus rhythm is also available. The underlying mechanisms may often be determined and these may have important therapeutic consequences.
