Cardiovascular instability, such as increased myocardial work and increased risk of tachydysrhythmia
, promotes thrombogenesis and platelet activation after ROSC and adverse immunomodulatory and metabolic effects.
6%, and is usually caused by the propagation of an atrial tachydysrhythmia
to the ventricles, by the accessory pathway (Fitzsimmons et al.
An implantable cardioverter-defibrillator (ICD) is a specialized device designed to directly treat a cardiac tachydysrhythmia
Increased vagal stimulation and slowed conduction of impulses through the atrioventricular node help to decrease tachydysrhythmias
MAP is our first line natural treatment for tachydysrhythmias
, especially when comorbidities such as dyslipidemia or metabolic syndrome exist.
Ipecac administration is relatively contraindicated following ingestion of cardiotoxic, highly vagomimetic plants that can cause nausea, vomiting, and bradycardia; often progressing to bradydysrhythmias, conduction blocks, and ventricular tachydysrhythmias.
Poisonings following ingestions of plants containing cardiac glycosides resemble digoxin toxicity with initial nausea, vomiting, and abdominal pain, followed by bradycardia with predisposition to hyperkalemia and ventricular tachydysrhythmias.
It generally should be used only for the patients who are unresponsive to supportive measures, have tachydysrhythmias
with hemodynamic compromise, intractable seizures unresponsive to benzodiazepines or extremely severe agitation or hallucinations unresponsive to other therapy.
In most cases, it occurs months after therapy is begun, typically with doses of [greater than or equal to]400 mg per day, although several cases of toxicity developing after 48 hours of intravenous therapy have been reported in patients with acute respiratory distress syndrome who were treated for tachydysrhythmias
Adams-Stokes seizures due to ventricular tachydysrhythmias
in patients with heart block: prevalence and problems of management.
Beta-blockers (metoprolol and bisoprolol) added to ACE inhibitors are also useful as a baseline treatment in most HF patients and may be especially useful in the case of tachydysrhythmias and in the postmyocardial infarction period.
May also be useful if concomitant tachydysrhythmias are present and in the post-MI period A (1b) Add carvedilol if not already taking beta- blocker or change current beta-blocker to carvedilol A (1b) NNT = 4 (2 years) to prevent hospitalization for HF.
