Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...

Abstract figure legend Cardiac cellular electrophysiology is modulated by multiple factors, including temperature, extracellular K+, heart rate/pacing frequency, and drugs. These modulators can have distinct effects on ion‐channel gating and transcription/trafficking over time.

Abstract figure legend Schematic illustrating the in silico study pipeline. A total of 50,000 virtual myocytes were generated, which were then filtered to 7093 myocytes that fit experimentally constrained biomarkers for physiological electrical and calcium behaviour under wild‐type conditions.

Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

A Natural History Study of Timothy Syndrome
Background Timothy syndrome (OMIM #601005) is a rare disease caused by variants in the gene CACNA1C. Initially, Timothy syndrome was characterized by a cardiac presentation of long QT syndrome and syndactyly of the fingers and/or toes, all associated ...

hERG1 channels and potential therapeutics for long QT syndrome
Abstract figure legend Prolonged QT results from hERG1 channel dysfunction. (A) Physiological anterograde trafficking of hERG1 channels to the plasma membrane, leading to a normal electrocardiogram. (B) Prolonged QT results from the presence of fewer hERG1 channels on the plasma membrane due to decreased anterograde trafficking or reduced function due ...

ABSTRACT Quizartinib is a tyrosine kinase inhibitor with single agent activity in patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) and has demonstrated efficacy in first‐line therapy when combined with intensive chemotherapy in both FLT3 ITD‐negative and positive AML.

Postoperative Takotsubo Cardiomyopathy in a Young Woman: A Case Report
Timeline of the patient's clinical course. ABSTRACT Takotsubo cardiomyopathy (TCM) can occur in young adults exposed to extreme physical stress, such as surgery, sepsis, and transfusion reactions. Mechanical recovery may precede electrical normalization, with ECG abnormalities persisting despite improved left ventricular ejection fraction (LVEF). Early
