Left Bundle Branch Area Pacing Reverts Electromechanical Window Negativity to a Similar Extent as Biventricular Pacing

Pacing and Clinical Electrophysiology, EarlyView.
BiVP = biventricular pacing; CRT = cardiac resynchronization therapy; EMW = electromechanical window; LBBAP = left bundle branch area pacing; QAoC = Time interval from the onset of the QRS complex to the center of the aortic valve closure artifact; QT = QT interval measured by tangent method.

Werner Irnich: Pioneer in the Development of the Dual‐Chamber Pacemaker—An Obituary

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Fifty years ago, Werner Irnich presented the concept of an optimal pacemaker capable of responding appropriately to various cardiac arrhythmias and perceptual disturbances, and intended to be used in 85% of patients. With this concept, Irnich was far ahead of his time. His proposed circuitry for AV block and atrial fibrillation, as well as his

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

In silico predictions of action potential propagation in doxorubicin cardiotoxicity: A parametric study using preclinical 3D magnetic resonance imaging‐based fibrotic left ventricle models

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the study's methodology and key findings. In a preclinical swine model, doxorubicin administration induced cardiotoxicity, characterized by diffuse fibrotic remodelling and altered electrical function, as assessed by magnetic resonance (MR) imaging and electrophysiological mapping.
