Sympathovagal imbalance in hyperthyroidism.
We assessed sympathovagal balance in thyrotoxicosis. Fourteen patients with Graves' hyperthyroidism were studied before and after 7 days of treatment with propranolol (40 mg 3 times a day) and in the euthyroid state. Data were compared with those obtained in a group of age-, sex-, and weight-matched controls. Autonomic inputs to the heart were assessed by power spectral analysis of heart rate v...
متن کاملSleep-related sympathovagal imbalance in SHR.
The role of the autonomic nervous system in spontaneous hypertension during each stage of the sleep-wake cycle remains unclear. The present study attempted to evaluate the differences in cardiac autonomic modulations among spontaneously hypertensive rats (SHR), normotensive Wistar-Kyoto rats (WKY), and Sprague-Dawley rats (SD) across sleep-wake cycles. Continuous power spectral analysis of elec...

BACKGROUND Due to the rise in the number of reports of stress cardiomyopathy in the literature, awareness of this condition is increasing. Although different names have been used to describe this condition, the similarities in clinical, electrocardiographic, echocardiographic, and angiographic features suggest that they represent the same spectrum of diseases with different underlying causes.

متن کاملTakotsubo Cardiomyopathy
Since the first report in 1990, takotsubo cardiomyopathy (TTC) has been increasingly recognized as a novel form of nonischemic acute cardiomyopathy. It is an important differential in diagnosis of acute coronary syndrome (ACS) due to its similar presentation. However, it distinguishes itself from an ACS in the fact that regional wall motion abnormalities extend beyond a single coronary vascular...
متن کاملTakotsubo cardiomyopathy.
Recently, many reports have been published about apical ballooning or takotsubo cardiomyopathy. This disease is a new entity of acute reversible heart failure. Abnormal catecholamine dynamics due to stress may be the primary cause of this condition.
