Electrophysiological and structural determinants of electrotonic modulation of repolarization by the activation sequence

Frontiers in Physiology, 2013
Spatial dispersion of repolarization is known to play an important role in arrhythmogenesis. Electrotonic modulation of repolarization by the activation sequence has been observed in some species and tissue preparations, but to varying extents. Our study

Human Ventricular Action Potential Duration Restitution

Journal of the American College of Cardiology, 2008
We read with interest the paper by Narayan et al. ([1][1]) that related right ventricular (RV) action potential duration (APD) restitution slopes to the presence of T-wave alternans (TWA) and ventricular tachycardia (VT) inducibility in patients with left ventricular (LV) dysfunction (LV ...

Relationship between electrocardiogram and intracellular action potential or extracellular action potential [PDF]

, 2007
P(論文)An analysis of the relation between electrocardiogram (ECG) and intracellular action potential in heart cells was performed using two considerations, that is, with the extracellular action potential induced from the differentiated intracellular ...

Action potential duration in ventricular muscle during selective metabolic block

, 1987
We have examined whether maintenance of the cardiac action potential duration depends exclusively on energy from glycolysis. Oxidative phosphorylation in guinea pig papillary muscles was inhibited by superfusion with hypoxic solutions.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Voltage noise influences action potential duration in cardiac myocytes [PDF]

Mathematical Biosciences, 2007
Stochastic gating of ion channels introduces noise to membrane currents in cardiac muscle cells (myocytes). Since membrane currents drive membrane potential, noise thereby influences action potential duration (APD) in myocytes. To assess the influence of noise on APD, membrane potential is in this study formulated as a stochastic process known as a ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Safety of Daprodustat for the Treatment of Chronic Kidney Disease Anemia: Final Analysis of a Multicenter Postmarketing Surveillance Study in Japan

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This final analysis of a multicenter, prospective postmarketing surveillance study evaluated the safety of daprodustat in patients with chronic kidney disease anemia in routine clinical practice in Japan. Methods Patients who initiated daprodustat between September 2020 and July 2022 were registered.

Association Between Individualized Education for Kidney Replacement Therapy Modality Selection and Peritoneal Dialysis Initiation: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) is an established home‐based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD.

Excitation and electroporation in genetically engineered excitable S-HEK cells exposed to electric pulses of different durations

Scientific Reports
Electroporation affects action potential generation in excitable cells such as nerve, muscle and cardiac cells. Since electroporation-based treatments use different pulse protocols, we investigated how electric pulses of different duration (from 500 ns ...
