Radiofrequency Catheter Ablation of Atrioventricular Nodal Reentrant Tachycardia: It Is Not Always As It Is Expected [PDF]

, 2004
Observation of Coincident arrhythmias is not uncommon but the co-existence of idiopathic verapamil sensitive left ventricular tachycardia (ILVT) with other arrhythmias is very rare.

Three-dimensional transesophageal echocardiography-guided transcathetar closure of ruptured noncoronary sinus of valsalva aneurysm

Annals of Cardiac Anaesthesia, 2017
Sinus of Valsalva aneurysm accounts for only 1% of congenital cardiac anomalies. Sinus of Valsalva aneurysm can cause aortic insufficiency, coronary artery flow compromise, cardiac arrhythmia, or aneurysm rupture.

Peritraumatic dissociation revisited: associations with autonomic activation, facial movements, staring, and intrusion formation

European Journal of Psychotraumatology, 2021
Background: Peritraumatic dissociation is purported to emerge together with attenuated autonomic arousal, immobility, and staring. However, empirical evidence is scarce and heterogeneous.

Automatic diagnostics of extrasystoles during cardiointervalogram preliminary assessment (filtration) in systems for heart rate variability analysis

Российский кардиологический журнал, 2005
Heart rate variability analysis requires the following: registered rhythm must be sinus one, regular or arrhythmic; cardiac arrhythmias should be diagnosed automatically and interpoled without disturbing RR interval dynamic row.

Sodium current reduction unmasks a structure-dependent substrate for arrhythmogenesis in the normal ventricles. [PDF]

PLoS ONE, 2014
Organ-scale arrhythmogenic consequences of source-sink mismatch caused by impaired excitability remain unknown, hindering the understanding of pathophysiology in disease states like Brugada syndrome and ischemia.We sought to determine whether sodium ...

Heart Rate Monitoring During Different Lung Volume Phases Using Seismocardiography

, 2018
Seismocardiography (SCG) is a non-invasive method that can be used for cardiac activity monitoring. This paper presents a new electrocardiogram (ECG) independent approach for estimating heart rate (HR) during low and high lung volume (LLV and HLV ...

Post-operative atrial fibrillation is influenced by beta-blocker therapy but not by pre-operative atrial cellular electrophysiology [PDF]

, 2006
We investigated whether post-cardiac surgery (CS) new-onset atrial fibrillation (AF) is predicted by pre-CS atrial cellular electrophysiology, and whether the antiarrhythmic effect of beta-blocker therapy may involve pre-CS pharmacological remodeling ...

Nonlinear trend removal should be carefully performed in heart rate variability analysis [PDF]

, 2016
$\bullet$ Background : In Heart rate variability analysis, the rate-rate time series suffer often from aperiodic non-stationarity, presence of ectopic beats etc. It would be hard to extract helpful information from the original signals.

Sleep apnea and the impact on cardiovascular risk in patients with Marfan syndrome [PDF]

, 2019
Background: Marfan syndrome (MFS) is an inherited connective tissue disorder characterized by ectopia lentis, aortic root dilation and dissection and specific skeletal features.

Comparison of Cardiac Arrhythmias between Late Pregnancy and Early Post-partum Periods in Clinically Healthy Iranian Fat-Tailed Sheep [PDF]

Pakistan Veterinary Journal, 2011
The current study was conducted to find out the prevalence of cardiac arrhythmias in clinically healthy Iranian fat-tailed sheep in two physiological states, i.e., late pregnancy and early post-partum periods.
