Autonomic control of the heart has a significant influence over development of life
threatening arrhythmias that can lead to sudden cardiac death. Sympathetic activity is known …

Cardiac neurotransmission imaging with SPECT and PET allows in vivo assessment of
presynaptic reuptake and neurotransmitter storage as well as of regional distribution and …

Objectives. The purpose of this study was to better understand the effects of long-term right
ventricular pacing on left ventricular perfusion, innervation, function and histology …

Objective: To improve the differential diagnosis between patients with multiple system
atrophy (MSA) and idiopathic PD (IPD) with autonomic failure. Background: Some patients …

Background—Left ventricular (LV) systolic dysfunction has been reported in humans with
subarachnoid hemorrhage (SAH), and its underlying pathophysiology remains controversial …

This book presents a new homeostatic theory of stress and distress and uses it to explain
how systems using the endogenous catecholamines—norepinephrine, epinephrine, and …

BACKGROUND In patients with arrhythmogenic right ventricular cardiomyopathy (ARVC),
the frequent provocation of ventricular tachycardia during exercise, the sensitivity toward …

Iodine-123 meta-iodobenzylguanidine ([123I] MIBG), an analogue of norepinephrine, is a
tracer for functioning of sympathetic neurons. To investigate cardiac sympathetic function in …

Background: Differential diagnosis between idiopathic Parkinson's disease (PD) and
multiple system atrophy (MSA) is often difficult in early disease stages. Since MSA is …

Background: The sequelae of severe brain injury include myocardial dysfunction. We sought
to describe the prevalence and characteristics of myocardial dysfunction seen in the context …
