CaMKII-dependent regulation of cardiac Na(+) homeostasis. [PDF]

, 2014
Na(+) homeostasis is a key regulator of cardiac excitation and contraction. The cardiac voltage-gated Na(+) channel, NaV1.5, critically controls cell excitability, and altered channel gating has been implicated in both inherited and acquired arrhythmias.

Collaborative Multirobot Navigation‐Assisted Magnetic Catheter Guidance and Shape Perception with Vascular Ultrasound and Electromagnetic Tracking

Advanced Intelligent Systems, EarlyView.
The article develops a collaborative multirobot navigation system‐assisted magnetic catheter guidance and shape perception method using the information fusion of robotic vascular ultrasound imaging and electromagnetic tracking to reconstruct the 3D catheter's shape and vasculature. Results verify the effectiveness of the system and the potential of the

Early afterdepolarisations and ventricular arrhythmias in cardiac tissue: a computational study

, 2009
Afterdepolarisations are associated with arrhythmias in the heart, but are difficult to study experimentally. In this study we used a simplified computational model of 1D and 2D cardiac ventricular tissue, where we could control the size of the region ...

Truncating Variants in RREB1 Cause a Novel RASopathy Syndrome of Congenital Heart Disease, Genitourinary Malformations, and Developmental Delay

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The interstitial 6p microdeletion syndrome is characterized by dysmorphic facies and structural heart, kidney, brain, and musculoskeletal differences. RREB1 haploinsufficiency and consequent abnormal RAS‐MAPK pathway signaling have been proposed as a driver of the disease phenotype; however, apart from a single case report, the phenotype of ...

The Expanding Clinical and Genetic Spectrum of Muscle Glycogen Storage Disease 0, (GSD0B)

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Glycogen storage disorders are a group of genetic disorders affecting glucose homeostasis in the body. Muscular glycogen stores are essential for liberating glucose for energy supply during bursts of activity and sustained muscle work. Muscle glycogen storage disease 0 (GSD0B) is associated with biallelic variants in GYS1 causing muscular ...

Cryothermal Energy Ablation Of Cardiac Arrhythmias 2005: State Of The Art [PDF]

, 2005
At the time of antiarrhythmic surgery, cryothermal energy application by a hand-held probe was used to complement dissections and resections and permanently abolish the arrhythmogenic substrate.

Neuraxial modulation for treatment of VT storm. [PDF]

, 2014
In the hyperadrenergic state of VT storm where shocks are psychologically and physiologically traumatizing, suppression of sympathetic outflow from the organ level of the heart up to higher braincenters plays a significant role in reducing the propensity

Alcohol consumption, sinus tachycardia, and cardiac arrhythmias at the Munich Octoberfest: results from the Munich Beer Related Electrocardiogram Workup Study (MunichBREW)

European Heart Journal, 2017
Aims Alcohol is a risk factor for cardiac arrhythmias. Retrospective analyses suggest supraventricular arrhythmias consecutive to acute alcohol consumption, but prospective data are limited.
