Takotsubo cardiomyopathy and new-onset right bundle branch block in uncomplicated right ventricle pacing: Cause or coincidence?

Journal of Indian College of Cardiology, 2021
Normally in the right ventricular (RV) paced rhythm, the electrocardiogram pattern will be of left bundle branch block (LBBB) pattern. A small percentage of patients can have right bundle branch block (RBBB) pattern in uncomplicated RV pacing.

Alternating wide complex tachycardia after surgical aortic valve replacement

Indian Pacing and Electrophysiology Journal, 2021
A 51-year-old male developed recurrent episodes of palpitations and pre-syncope after surgical aortic valve replacement. Electrocardiograms after surgery revealed a wide complex tachycardia with alternating left bundle branch and right bundle branch ...

His bundle pacing after failure of cardiac resynchronization therapy: a case study

Journal of International Medical Research, 2020
His bundle pacing is a relatively new method of cardiac pacing. This method is used in patients with atrioventricular block to prevent heart failure associated with right ventricular pacing, and in patients with bundle branch block and cardiomyopathy. We

Peeling off the Mask: Pseudo Myocardial Infarction Pattern on Electrocardiogram During AICD Implantation

Indian Pacing and Electrophysiology Journal, 2015
Lead induced transient right bundle branch block is not uncommon during pacemaker implantation. We describe a patient with old anterior wall myocardial infarction with severe left ventricular dysfunction presenting with recurrent ventricular tachycardia ...

The Spatial Vectorcardiogram in Right Bundle Branch Block [PDF]

Circulation, 1951
The spatial vectorcardiograms of 24 subjects with electrocardiographic evidence of right bundle branch block are described. Correlation of the vectorcardiographic patterns observed, with clinical and roentgenologic data, suggests that the recognition of ventricular hypertrophy in the presence of such a conduction defect may be improved by this method ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
