PERSISTENT EXERTIONAL DYSPNEA AND PALPITATIONS - HARBINGERS OF AN INFILTRATED HEART

Exertional dyspnea and ventilation in hyperthyroidism.

Dyspnea is recognized to be an important feature in patients with hyperthyroidism at rest and during exercise. However, its etiology is not well-understood. Since dyspnea is thought to be related to the perception of excessive ventilatory effort, we explored the possibility that dyspnea in these patients might be related to an inappropriate ventilatory response to the increased metabolic rate. ...

Failing phrenics: an obscure cause of exertional dyspnea

INTRODUCTION Idiopathic phrenic nerve palsy is a rare cause of exertional dyspnea. We present a case of a patient presenting with worsening dyspnea of an unknown etiology found to be related to bilateral phrenic nerve palsy. DISCUSSION Forty-two-year-old man presented to our emergency department with exertional dyspnea, orthopnea, and a left lower lobe consolidation treated initially as bronc...

Preliminary investigation of cardiopulmonary function in stroke patients with stable heart failure and exertional dyspnea

The aim of this study was to investigate the relationships between pulmonary function, respiratory muscle strength, perceived dyspnea, degree of fatigue, and activity of daily living with motor function and neurological status in stroke patients with stable congestive heart failure (CHF).This was a cohort study in a tertiary care medical center. Stroke patients with CHF and exertional dyspnea (...

Pulmonary function in rheumatic heart disease and its relation to exertional dyspnea in ambulatory patients.

Pulmonary and cardiocirculatoiy function were studied in 21 ambulatory patients with rheumatic heart disease. A pattern of pulmonary function was observed which deviated from normal to a degree insufficient to account for the exertional dyspnea of these patients. The pathogenesis of this symptom is, therefore, discussed in relation to the observed cardiocirculatory abnormalities which were ofte...
