Bidirectional Cardio-Respiratory Interactions in Heart Failure

Frontiers in Physiology, 2018
We investigated cardio-respiratory coupling in patients with heart failure by quantification of bidirectional interactions between cardiac (RR intervals) and respiratory signals with complementary measures of time series analysis.

Pacemaker implantation following tricuspid valve annuloplastyCentral MessagePerspective

JTCVS Open, 2023
Objective: Tricuspid annuloplasty is associated with increased risk of atrioventricular block and subsequent implantation of a permanent pacemaker. However, the exact incidence of permanent pacemaker, associated risk factors, and outcomes in this frame ...

Differentiation of Heart Failure Patients by the Ratio of the Scaling Exponents of Cardiac Interbeat Intervals

Frontiers in Physiology, 2019
Heart failure (HF) is one of the most frequent heart diseases. It is usually characterized with structural and functional cardiac abnormalities followed by dysfunction of autonomic cardiac control.

Splice variants of DOMINO control Drosophila circadian behavior and pacemaker neuron maintenance. [PDF]

, 2019
Circadian clocks control daily rhythms in behavior and physiology. In Drosophila, the small ventral lateral neurons (sLNvs) expressing PIGMENT DISPERSING FACTOR (PDF) are the master pacemaker neurons generating locomotor rhythms.

A breathing pacemaker

European Heart Journal - Cardiovascular Imaging, 2019
A 59-year-old man suffered from a pacemaker infection. He was born with a complex cardiac malformation (dextrocardia, transposition of the great arteries, and atrial switch). He was implanted of a bicameral pacemaker for complete atrioventricular block in 1995. [...]

Experimental analysis and computational modeling of interburst intervals in spontaneous activity of cortical neuronal culture [PDF]

, 2011
Rhythmic bursting is the most striking behavior of cultured cortical networks and may start in the second week after plating. In this study, we focus on the intervals between spontaneously occurring bursts, and compare experimentally recorded values with

Impact of Leadless Pacemaker Therapy on Cardiac and Atrioventricular Valve Function Through 12 Months of Follow-Up.

Circulation: Arrhythmia and Electrophysiology, 2019
BACKGROUND Endocardial pacemaker leads and right ventricular (RV) pacing are well-known causes of tricuspid valve, mitral valve, and cardiac dysfunction. Lead-related adverse consequences can potentially be mitigated by leadless pacemaker (LP) therapy by
