Long-QT Syndrome Secondary to Hypocalcemia
, 2011 Long-QT syndrome is a congenital or acquired disorder thatproduces sudden death due to ventricular arrhythmias. Electrolyte disturbances and medications are the most common causes of acquired long-QT syndrome.

The Journal of Physiology, EarlyView.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 ...

Identification of TREK channels in mouse intracardiac ganglion neurons
The Journal of Physiology, EarlyView.Abstract figure legend Role of TWIK‐related K+ (TREK) channels in intracardiac ganglion neurons. CD‐1 mice were used to establish primary cultures of intracardiac neurons for immunochemical characterization and patch‐clamp electrophysiology. Intracardiac neurons express functional TREK channels, which modulate neuronal excitability by regulating ...

Multifactorial QT Interval Prolongation and Takotsubo Cardiomyopathy
Case Reports in Cardiology, 2014 A 71-year-old woman collapsed while working as a grocery store cashier. CPR was performed and an AED revealed torsades de pointes (TdP). She was subsequently defibrillated resulting in restoration of sinus rhythm with a QTc interval of 544 msec.

The Journal of Physiology, EarlyView.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).
