Concealed WPW Syndrome with Longitudinal Dissociation in the His Bundle Exhibiting Five Different Electrocardiographic Waveforms During Tachycardia

Journal of Arrhythmia, 2005
We examined a patient with concealed WPW syndrome who exhibited five different electrocardiographic waveforms during tachycardia. With the intracardiac electrogram, all tachycardia were artrioventricular reciprocating tachycardia with retrograde ...

Programming Cardiac Resynchronization Therapy for Electrical Synchrony: Reaching Beyond Left Bundle Branch Block and Left Ventricular Activation Delay

Journal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2018
Background QRS narrowing following cardiac resynchronization therapy with biventricular (BiV) or left ventricular (LV) pacing is likely affected by patient‐specific conduction characteristics (PR, qLV, LV‐paced propagation interval), making a universal ...

Right Bundle Branch Block: Current Considerations

Current Cardiology Reviews, 2020
RBBB, a pattern seen on the 12-lead ECG, results when normal electrical activity in the His-Purkinje system is interrupted for some reason. The normal sequence of activation is altered in RBBB, with a resultant characteristic appearance on the ECG ...

Atrial Septal Defect Associated With Right Bundle Branch Block Masking Brugada Syndrome

JACC: Case Reports, 2023
A type 1 Brugada electrocardiogram pattern may be masked by typical right bundle branch block aspect. We present 2 cases (male patients, aged 18 and 22 years) of associated ostium secundum atrial septal defect with a right bundle branch block aspect and ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

FEBS Letters, EarlyView.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.
