These situations include focal neurological problems (e.g. inability to move a limb) and focal changes of the brain tissue on CT or MRI scan. [7] Evidence to support or refute the use of antiepileptic drugs as a preventive measure, however, is lacking. [22]
Superficial vein thrombosis (SVT) is a blood clot formed in a superficial vein, a vein near the surface of the body. Usually there is thrombophlebitis, which is an inflammatory reaction around a thrombosed vein, presenting as a painful induration (thickening of the skin) with redness.
Indications for Class Ia agents are supraventricular tachycardia, ventricular tachycardia, symptomatic ventricular premature beats, and prevention of ventricular fibrillation. Procainamide can be used to treat atrial fibrillation in the setting of Wolff–Parkinson–White syndrome , and to treat wide complex hemodynamically stable tachycardias .
Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. [1] POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, [10] including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea ...
This route of administration is often used to bypass the blood-brain barrier because it can prevent important medications from reaching the central nervous system. This injection method is widely used in diseased mice models to study the effect of drugs, plasmid DNA, and viral vectors on the central nervous system.
[10] [25] Medications for depression affect the transmission of serotonin, norepinephrine, and dopamine. [10] Older and less selective antidepressants like TCAs and MAOIs inhibit the reuptake or metabolism of norepinephrine and serotonin in the brain, which results in higher concentrations of neurotransmitters. [25]
An episode of SVT may present with palpitations, dizziness, shortness of breath, or losing consciousness (fainting). The electrocardiogram (ECG) would appear as a narrow-complex SVT. Between episodes of tachycardia the affected person is likely to be asymptomatic; however, the ECG would demonstrate the classic delta wave in Wolff–Parkinson ...
