Safety and Utility of Smartphone‐Based Heart Monitors in Pediatric Patients With Cardiovascular Implantable Electronic Devices

Journal of Cardiovascular Electrophysiology, EarlyView.
Smartphone heart monitors in pediatric CIEDs: A pilot study. Smartphone heart monitors did not induce EMI in children with CIEDs, enabling reliable heart rate measurement and accurate identification of ventricular non‐captures. ABSTRACT Background Portable heart monitors enable on‐demand electrocardiogram (ECG) recordings and enhance symptom‐rhythm ...

Diagnostic performance of SD‐ΔRR during physical stressors for identifying diabetic sensorimotor polyneuropathy

Journal of Diabetes Investigation, EarlyView.
Study population, methodology and key findings of the study. ABSTRACT Aims This study aimed to evaluate the clinical efficacy of SD‐ΔRR as a novel methodology for short‐duration heart rate variability (HRV) assessment for the diagnosis of diabetic sensorimotor polyneuropathy (DSPN) in patients with diabetes.

Characterisation of sleep apneas and respiratory circuitry in mice lacking CDKL5

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary CDKL5 deficiency disorder is a rare genetic disease caused by mutations in the CDKL5 gene. Central apneas during wakefulness have been reported in patients with CDKL5 deficiency disorder. Studies on CDKL5‐knockout mice, a CDKL5 deficiency disorder model, reported sleep apneas, but it is still unclear whether these events are central (central ...

Multifactorial QT Interval Prolongation and Takotsubo Cardiomyopathy

Case Reports in Cardiology, 2014
A 71-year-old woman collapsed while working as a grocery store cashier. CPR was performed and an AED revealed torsades de pointes (TdP). She was subsequently defibrillated resulting in restoration of sinus rhythm with a QTc interval of 544 msec.

QT Interval Evaluation in Right Ventricular Pacing: Validation of a Novel Formula

Pacing and Clinical Electrophysiology, EarlyView.
Abstract Background QT interval measurement in the presence of right ventricular pacing (RVP) represents a clinical challenge. We therefore aimed to derive and validate a formula for QT estimation during RVP in a large cohort of pacemaker patients. Methods and Results We prospectively enrolled 100 patients in a derivation cohort and 487 in a validation

The classical “R-on-T” phenomenon

Indian Heart Journal, 2015
The polymorphic ventricular tachycardia (PVT) is uncommon arrhythmia with multiple causes and has been classified according to whether they are associated with long QT interval or normal QT.

Drug-induced life-threatening arrhythmias and sudden cardiac death: A clinical perspective of long QT, short QT and Brugada syndromes

Revista Portuguesa de Cardiologia, 2018
Sudden cardiac death is a major public health challenge, which can be caused by genetic or acquired structural or electrophysiological abnormalities. These abnormalities include hereditary channelopathies: long QT, short QT and Brugada syndromes.

Hospitalized cancer patients with acquired long QT syndrome-a matched case-control study

Cardio-Oncology, 2020
Background Our recent study has revealed that many hospitalized patients with acquired long QT syndrome (ALQTS) are cancer patients. This study aims to determine the risk factors and outcomes of hospitalized cancer patients with ALQTS.
