Navigating the Lead Paradox: Successful Co‐Implantation of Cardiac Contractility Modulation Device and a Micra Leadless Pacemaker

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
This central illustration visually summarizes the first co‐implantation of a Cardiac Contractility Modulation (CCM) system and a Micra leadless pacemaker in a 78‐year‐old male with wild‐type transthyretin cardiac amyloidosis and NYHA Class III heart failure.

Arctic lake trout (Salvelinus namaycush) show evidence of seasonal acclimation of cardiac adrenergic sensitivity but not heat tolerance

open access: yesJournal of Fish Biology, EarlyView.
Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...

Distributional and Tail‐Dependent Perspectives in Economic Relationships: A Review of Quantile Regression Application

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT There is an increased proportion of studies using quantile‐based regression methodology (QR) in economics. They offer a robust alternative to classical mean regressions, which can estimate non‐normal variables with distributional heterogeneity in the dependent variable.

Profiling the sleep architecture of ageing adults using a seven‐state continuous‐time Markov model

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep is a complex biological process regulated by networks of neurons and environmental factors. As one falls asleep, neurotransmitters from sleep–wake regulating neurones work in synergy to control the switching of different sleep states throughout the night. As sleep disorders or underlying neuropathology can manifest as irregular switching,

QRS COMPLEX DURATION AND CLINICAL FEATURES OF PATIENTS WITH PERMANENT PACEMAKERS

open access: yesJournal of V. N. Karazin Kharkiv National University: Series Medicine, 2013
125 patients (57 – women, 68 – males) with permanent pacing were examined. Among the indications for pacemaker installation there were atrio-ventricular block (AV-block) – 77 people (62 ± 4 %), sick sinus node syndrome (SSNS) – 32 patients (26 ± 4 ...

Classification Probability Analysis for Arrhythmia and Ischemia Using Frequency Domain Features of QRS Complex [PDF]

open access: yesInternational Journal Bioautomation, 2015
Two of the most common cardiovascular diseases are myocardial ischemia and cardiac arrhythmias. Using the frequency domain features of QRS complex (i.e., frequency of the maximum peak in power spectrum and total average power) the proposed approach ...

Myocardial Infarction in Conduction System Pacing: Trust the ECG or Rely on Algorithms?

open access: yesPacing and Clinical Electrophysiology, EarlyView.
Abstract A 66‐year‐old male patient with a conduction system pacing (CSP) pacemaker, implanted after a pace‐and‐ablate strategy for persistent, poorly rate‐controlled atrial fibrillation, presented to the outpatient clinic with worsening dyspnea. Laboratory findings and ECG were indicative of an anterolateral ST‐segment elevation myocardial infarction (
