Current Topics of Progressive Cardiac Conduction Disease

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Many genes and the protein cause PCCD. Mutation of NaV1.5 or CX40 cause isolated PCCD, but mutation of lamin A/C, emerin, or desmin lead to cardiomyopathy, and PCCD. Mutation of transcription factor NCX2‐5, and Tbx5 associated with atrial septal defect and abnormal development of conduction system.

Time-frequency analysis of the ECG in the diagnosis of vasovagal syndrome in older people

The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
The Smoothed Pseudo Wigner-Ville Distribution (SPWVD) is used for the time-frequency analysis of variations in RR interval. A novel technique to determine the smoothing window lengths is implemented, and a new heart rate variability (HRV) metric is developed, instantaneous center frequency variability (ICFV), which uses the time-frequency map generated

Epidemiology of vasovagal syncope

, 2015
Vasovagal syncope is a common symptom, but its true incidence is difficult to estimate because only a small percentage of patients with syncope seek medical advice.

Management of sleep apnoea syndrome (SAS) in patients with vasovagal syncope (VVS): a protocol for the VVS-SAS cohort study

BMJ Open, 2020
Introduction Recurrent vasovagal syncope (VVS) is associated with decreased quality-of-life and frequent use of emergency services. The evidence base for causality, diagnostic procedures and potential VVS treatments is poor. Scattered observations in the

How to Prevent Recurrence of Idiopathic Lead Migration: A Case Report and Discussion of Management

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Reverse ratchet syndrome is an extremely rare form of idiopathic lead migration. Firm fixation of the lead sleeve to the fascia is crucial to prevent recurrence; however, even with reinforced fixation, muscle motion or intrinsic sleeve design may limit the ability to prevent idiopathic lead migration.

Hemodynamic Response to the Head-Up Tilt Test in Patients With Syncope as a Predictor of the Test Outcome: A Meta-Analysis Approach

Frontiers in Physiology, 2019
Aim: The paper presents a meta-analysis of studies comparing hemodynamic parameters: heart rate (HR), systolic blood pressure (sBP), diastolic blood pressure (dBP), and stroke volume (SV) measured during head-up tilt table test (HUTT) in patients with ...
