Bidirectional ventricular tachycardia in cardiac sarcoidosis. [PDF]

open access: yes, 2016
A 73-year-old man with history of pulmonary sarcoidosis was found to have runs of non-sustained bidirectional ventricular tachycardia (BVT) with two different QRS morphologies on a Holter monitor.

Comparative diagnostic accuracy study of point of care ultrasound techniques for detection of left atrial enlargement by hospital medicine physicians from archived echocardiogram images

open access: yesJournal of Hospital Medicine, EarlyView.
Abstract Background Left atrial enlargement (LAE) is predictive of cardiovascular morbidity and mortality. Prior studies of point‐of‐care ultrasound (POCUS) interpretation methods for identifying LAE utilized older echocardiographic reference ranges. Objectives Compare the test characteristics of hospitalist‐performed POCUS techniques for identifying ...

Right atrial appendage tachycardia: A rare cause of tachycardia induced cardiomyopathy in a 4-year-old child

open access: yesIndian Pacing and Electrophysiology Journal, 2018
We present a rare case of tachycardiomyopathy in a 4-year-old girl. The child had incessant atrial tachycardia (AT) and refractory heart failure. Right atrial appendage (RAA) was localised as the source of the ectopic tachycardia.

Atrial fibrillation and electrophysiology in transgenic mice with cardiac-restricted overexpression of FKBP12 [PDF]

open access: yes, 2019
Cardiomyocyte-restricted overexpression of FK506-binding protein 12 transgenic (αMyHC-FKBP12) mice develop spontaneous atrial fibrillation (AF). The aim of the present study is to explore the mechanisms underlying the occurrence of AF in αMyHC-FKBP12 ...

Cardiac resynchronization therapy and pulmonary artery banding in advanced heart failure infants with left ventricular dilated cardiomyopathy and left bundle branch block

open access: yesPediatric Investigation, EarlyView.
The combination of cardiac resynchronization therapy and pulmonary artery banding was associated with substantial improvement in advanced heart failure infants with left ventricular dilated cardiomyopathy and left bundle branch block. Most patients exhibited marked improvement in clinical status and ventricular function, along with a reduction in QRS ...

Unidirectional block on the mitral isthmus during radiofrequency application for perimitral atrial tachycardia

open access: yesJournal of Arrhythmia, 2013
We present the case of a patient who developed regular, narrow QRS tachycardia after ablation for long-standing persistent atrial fibrillation. During the electrophysiological study, this tachycardia was diagnosed as macroreentrant atrial tachycardia ...

Left Atrial Roof-Dependent Atrial Tachycardia Mimicking a Posterior Focal Atrial Tachycardia

open access: yesJACC: Clinical Electrophysiology, 2019
A 77-year-old woman who had previously undergone pulmonary vein (PV) isolation for persistent atrial fibrillation underwent a second procedure for a recurrent atrial tachycardia (AT). The clinical AT was a dual-loop AT with left atrial (LA) roof-dependent and anterior macro-re-entrant circuits ...

Cardiac disease in systemic sclerosis: Integrating pathobiology with clinical management

open access: yesRheumatology &Autoimmunity, EarlyView.
Abstract Systemic sclerosis (SSc) is a complex autoimmune disorder in which cardiovascular involvement remains a major determinant of morbidity and mortality. Cardiac injury in SSc results from the interplay of microvascular dysfunction, immune‐mediated inflammation, and progressive interstitial and replacement fibrosis, leading to myocardial disease ...

Are physiological oscillations physiological?

open access: yesThe Journal of Physiology, EarlyView., 2023
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.
