Chronological T-wave alternation before and after the onset of arrhythmogenic right ventricular cardiomyopathy.

Ann Noninvasive Electrocardiol 2022 Jun 2:e12965. Epub 2022 Jun 2.

Department of Pediatrics, Iwate Medical University, Shiwa, Japan.

Identification of arrhythmogenic right ventricular cardiomyopathy (ARVC) during childhood is challenging due to the lack of specific ECG manifestation. We report chronological ECG alteration before several years of the ARVC onset in two affected children. Their ECG at the age of 6 years was almost normal for their age, and their chronological ECGs exhibited inversion of T wave in inferior leads, which are typical for ARVC, developed at younger age than that in precordial leads.

Acute echocardiographic and hemodynamic response to his-bundle pacing in patients with first-degree atrioventricular block.

Ann Noninvasive Electrocardiol 2022 Apr 21:e12954. Epub 2022 Apr 21.

Division of Cardiology, Department of Medicine, Duke University, Durham, North Carolina, USA.

Background: Atrial pacing and right ventricular (RV) pacing are both associated with adverse outcomes among patients with first-degree atrioventricular block (1°AVB). His-bundle pacing (HBP) provides physiological activation of the ventricle and may be able to improve both atrioventricular (AV) and inter-ventricular synchrony in 1°AVB patients. This study evaluates the acute echocardiographic and hemodynamic effects of atrial, atrial-His-bundle sequential (AH), and atrial-ventricular (AV) sequential pacing in 1°AVB patients. Read More

Rapid wide QRS tachycardia with an unknown cause.

Ann Noninvasive Electrocardiol 2022 Apr 16:e12959. Epub 2022 Apr 16.

Department of Electrocardiography, The First Affiliated Hospital of USTC, Division of Life Sciences and Medicine, University of Science and Technology of China, Hefei, China.

One-to-one atrioventricular conduction during atrial flutter is one of the most severe life-threatening arrhythmias and is hemodynamically perilous. Rapid wide QRS tachycardia often not only occurs in patients with ventricular tachycardia but is also found in supraventricular tachycardia/atrial flutter with preexistent QRS prolongation, supraventricular tachycardia/atrial flutter with QRS prolongation caused by an IC antiarrhythmic drug, and supraventricular tachycardia/atrial flutter with preexcitation. Furthermore, atrial flutter with 1:1 AVC via an accessory pathway is an uncommon presentation of Wolff-Parkinson-White syndrome. Read More

Torsade de pointes caused by citalopram during the pacemaker battery-depletion phase: A case report.

Ann Noninvasive Electrocardiol 2022 Mar 24:e12936. Epub 2022 Mar 24.

Department of Cardiology, The Affiliated Hospital of Yunnan University, Kunming, China.

Drug-induced QT prolongation, primarily antiarrhythmic drugs, is a common cause of torsade de pointes (TdP). Although there have been previous reports of drug-induced TdP in patients, it has not been well documented when caused by citalopram during the pacemaker battery-depletion phase. To improve delirium recognition, we report a case of citalopram-induced TdP during the pacemaker battery-depletion phase. Read More
