tachydysrhythmia

tachydysrhythmia

 
an abnormal heart rhythm with rate greater than 100 beats per minute in an adult; the term tachyarrhythmia is usually used instead.

Sinus tachycardia is the most frequently encountered dysrhythmia (87%), and asystole, ventricular tachydysrhythmia, and sinus bradycardia, which are the most lethal ictal dysrhythmias, occur in less than 5%-10% of cases (1).
However, sudden cardiac death risk in people with WPW is less than 0.6%, and is usually caused by the propagation of an atrial tachydysrhythmia to the ventricles, by the accessory pathway (Fitzsimmons et al., 2001; Munger et al., 1993).
Initially, patients were included if they presented with "tachydysrhythmia associated with symptoms requiring cardioversion (unstable tachydysrhythmia with palpable pulse regarding patient conditions)." This criterion may include both ventricular and supraventricular tachyarrhythmias.
An implantable cardioverter-defibrillator (ICD) is a specialized device designed to directly treat a cardiac tachydysrhythmia. High level of alcohol consumption, cholesterol levels and smoking obesity contribute to heart disease; continence of such lifestyle will increase the requirement of ICD implants.
When tachydysrhythmia associated with symptoms requiring cardioversion (unstable tachydysrhythmia with palpable pulse regarding patient conditions) was detected, patients were transferred to the Cardiopulmonary Resuscitation Unit and they underwent cardiac monitoring, pulse oximetry, and obtaining capnography.
Tachydysrhythmias occur more frequently after intrapericardial dissection and in patients who have postoperative interstitial or perihilar pulmonary edema [4].
Digoxin (Lanoxin[R]) can improve cardiac output and decrease tachydysrhythmias, especially when initially given.
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. Finally, induction of emesis with ipecac could delay critical administration of activated charcoal solutions which have fewer adverse effects and bind many plant-derived toxins; most of which are uncharged, of relatively low molecular weight with extensive volumes of distribution, and not amenable to removal by hemodialysis.
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. Presumably, the alveolar damage leads to impaired surfactant metabolism and makes amiodorone clearance more difficult.
