Diminished tyrosine hydroxylase immunoreactivity in the cardiac conduction system and myocardium in Parkinson’s disease: an anatomical study

Acta Neuropathologica, 2009
Clinical and autopsy studies have consistently reported cardiac sympathetic dysfunction in the left ventricular wall in patients with Parkinson's disease (PD). Whether the nerve fibers of the cardiac conduction system or the atrial walls are equally affected in this disease process has not yet been well documented.

Hereditary Long QT Syndrome Associated with Cardiac Conduction System Disease

PACE - Pacing and Clinical Electrophysiology, 1989
This report describes the cardiac conduction abnormalities, detected by invasive electrophysiological study, in two identical siblings with symptomatic congenital long QT syndrome. Both patients had evidence of intra‐Hisian conduction delay in response to programmed atrial stimulation and pacing induced infranodal block was seen in one of the two ...

The cardiac conduction system: History, development, and disease

Current Topics in Developmental Biology
The heart is the first organ to form during embryonic development, establishing the circulatory infrastructure necessary to sustain life and enable downstream organogenesis. Critical to the heart's function is its ability to initiate and propagate electrical impulses that allow for the coordinated contraction and relaxation of its chambers, and thus ...

Symptomatic Conduction System Disease in Cardiac Amyloidosis

The American Journal of Cardiology, 1997
Symptomatic conduction system disease in cardiac amyloidosis and its management has been reported infrequently. We report our experience of patients with amyloidosis having symptomatic conduction system disease requiring permanent pacemaker implantation.

Can Cardiac Conduction System Disease Be Prevented?

JAMA Internal Medicine, 2016
Cardiac conduction system disorders on the electrocardiogram (ECG) are common. Left bundle branch block (LBBB) is associated with adverse outcomes, and variants previously considerednormal, suchas rightbundlebranchblock (RBBB),1 left anterior fascicularblock,2orPR intervalprolongation,3may also portend morbidity andmortality. At present, no paradigm to

Hypertrophic Cardiomyopathy and Symptomatic Conduction System Disease in Cardiac Amyloidosis

Southern Medical Journal, 2006
Cardiac involvement is the most important prognostic factor in primary amyloidosis (AL). The clinical presentation of amyloid cardiomyopathy is varied and may manifest as heart failure, brady or tachyarrhythmias, syncope, angina and rarely with features of hypertrophic cardiomyopathy and advanced symptomatic conduction system disease. The management of

Conduction System Disease in Fetuses Evaluated for Irregular Cardiac Rhythm

Fetal Diagnosis and Therapy, 2006
<i>Objectives:</i> To determine the prevalence of 1st and 2nd degree AV block in fetuses with an irregular cardiac rhythm, and to summarize outcome of these pregnancies. <i>Background:</i> The diagnosis of irregular cardiac rhythm or ‘skipped beats’ includes isolated ectopy that resolves spontaneously.

Prevalence, Incidence, and Impact on Mortality of Conduction System Disease in Transthyretin Cardiac Amyloidosis

The American Journal of Cardiology, 2020
Transthyretin cardiac amyloidosis (ATTR-CA) is an increasingly recognized infiltrative cardiomyopathy in which conduction system disease is common. The aim of our study was to define the incidence and prevalence of high-grade atrioventricular (AV) block requiring pacemaker implantation in our quaternary referral center.
