Isoproterenol

Isoprenaline


Presentation

  • A series of 12 patients with shock that followed bacteremia due to gram-negative pathogens is presented, and a case is reported. The hemodynamic alterations that occur in such patients are discussed.[ncbi.nlm.nih.gov]
Coarctation of the Aorta
  • BACKGROUND: The exercise test is considered useful in selecting high-risk patients with repaired coarctation of the aorta (CoA), but it is difficult to obtain the cooperation of pediatric patients.[ncbi.nlm.nih.gov]
Weight Loss
  • Because bradycardia associated with weight loss in anorexia is usually a physiologic adaptation and rarely symptomatic, aggressive chronotropic therapy may be not only unwarranted, but potentially deleterious.[ncbi.nlm.nih.gov]
Hypothermia
  • The patient then presented with electrical storm with 8 successive episodes of ventricular fibrillation while on deep sedation and hypothermia. Isoproterenol infusion was introduced, leading to rapid cessation of any arrhythmic event.[ncbi.nlm.nih.gov]
Respiratory Distress
  • Thirty-six hours following the institution of therapy, while the isoproterenol was being tapered, the patient experienced an increase in respiratory distress followed by cardiac arrest.[ncbi.nlm.nih.gov]
Tachycardia
  • No tachycardias were induced during programmed electrical stimulation.[ncbi.nlm.nih.gov]
Panic Attacks
  • Two subjects reported the development of spontaneous panic attacks during the follow-up period; one related the development of these attacks to the infusion experience.[ncbi.nlm.nih.gov]
Meningism
  • We present the case of a previously healthy 2-year-old boy diagnosed with listeria meningitis.[ncbi.nlm.nih.gov]

Workup

Narrow QRS Complex
  • A narrow QRS complex tachycardia with a retrograde P wave in the ST segment was recorded in 24-h Holter monitoring. An electrophysiologic study was performed while he was in a nonsedated state.[ncbi.nlm.nih.gov]
Prolonged QT Interval
  • The latter predisposes to atypical ventricular tachycardia (torsade de pointes) when premature ventricular depolarizations occur during the prolonged QT interval.[ncbi.nlm.nih.gov]
Atrioventricular Dissociation
  • In the setting of increased intracranial pressure (ICP), various rhythm disturbances have been associated, ranging from tachyarrhythmias to bradyarrhythmias with atrioventricular dissociation.[ncbi.nlm.nih.gov]
Hepatocellular Carcinoma
  • Abstract Increasing data indicate that stress hormones and their corresponding receptors play an important role in the carcinogenesis and progression of hepatocellular carcinoma (HCC).[ncbi.nlm.nih.gov]

Treatment

  • We recently utilized continuous infusion intravenous isoproterenol in the treatment of respiratory failure in an 18-yr-old steroid-dependent asthmatic female.[ncbi.nlm.nih.gov]

Prognosis

  • The prognosis of the patient is essentially determined by the severity in morphological changes, however, high pulmonary vascular resistance in the neonatal period may aggravate tricuspid regurgitation and lead to functional pulmonary atresia.[ncbi.nlm.nih.gov]

Etiology

  • The etiology of her electrocardiographic pattern was evaluated by isoproterenol infusion test and was revealed to be an early repolarization.[ncbi.nlm.nih.gov]
  • Intravenous As a diagnostic agent Adult: For diagnosing etiology of mitral regurgitation: 4 mcg/minute as infusion. For diagnosis of coronary artery disease or lesions: 1-3 mcg/minute as infusion.[drugsupdate.com]
  • As an aid in diagnosing etiology of mitral regurgitation . Adults: I.V. infusion of 4 mcg/minute. As an aid in diagnosing coronary artery disease or lesions . Adults: I.V. infusion of 1 to 3 mcg/minute.[glowm.com]
