Atropine is often used as a first line treatment of a third-degree heart block in the presence of a narrow QRS which indicates a nodal block, but, may have little to no effect in an infra-nodal block. [11] Atropine works by reducing vagal stimulation through the AV node but will not be effective in those who have had a previous heart transplant ...
Borrelia miyamotoi is a bacterium of the spirochete phylum in the genus Borrelia.A zoonotic organism, B. miyamotoi can infect humans through the bite of several species of hard-shell Ixodes ticks, the same kind of ticks that spread B. burgdorferi, the causative bacterium of Lyme disease.
Lyme disease, also known as Lyme borreliosis, is a tick-borne disease caused by species of Borrelia bacteria, transmitted by blood-feeding ticks in the genus Ixodes. [4] [9] [10] The most common sign of infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week afterwards. [1]
Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome [4] [5] Other presenting signs or ...
Norepinephrine (Levophed) is the most common first-line vasopressor for people who don't respond well to other hypotension treatments such as fluid resuscitation. Atropine is administered for bradycardia. It acts on the vagus nerve so it's not effective in heart transplant patients as the vagus nerve is severed during the transplant.
Major US medical authorities, including the Infectious Diseases Society of America, [5] the American Academy of Neurology, [6] and the National Institutes of Health, [7] are careful to distinguish the diagnosis and treatment of "patients who have had well-documented Lyme disease and who remain symptomatic for many months to years after ...
The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden cardiac death due to ventricular fibrillation and ventricular tachycardia. [1] "AICD" was trademarked by the Boston Scientific corporation, so the more generic "ICD" is preferred terminology.
Borrelia burgdorferi is a bacterial species of the spirochete class in the genus Borrelia, and is one of the causative agents of Lyme disease in humans. [1] [2] Along with a few similar genospecies, some of which also cause Lyme disease, it makes up the species complex of Borrelia burgdorferi sensu lato.
