More serious medical conditions, such as bradyarrhythmia
and hypertension, have also been diagnosed in snorers.
are more frequent than tachyarrhythmias; supraventricular tachycardias occur more frequently than ventricular tachycardias in the paediatric setting(1,2,4,5).
The ICD reliably terminates the vast majority of life-threatening tachyarrhythmias by initiating rapid pacing or delivering a shock as appropriate, and provides pacing in the case of bradyarrhythmias
(Exner, Klein, & Prystowsky, 2001).
The AHA recommends the QT interval should be measured in patients who have received any antiarrhythmic drug known to cause TdP, overdosed from a potentially proarrhythmic agent, developed new-onset bradyarrhythmias
, severe hypokalemia or hypomagnesemia, require antipsychotics, and experienced an acute neurological event (Drew, 2005).
The company's pacing leads are used in connection with third-party pacemakers--both implantable and temporary pacemakers systems--that are used to treat cardiac bradyarrhythmias
(an adult heart rate below 60 beats per minute) and other coronary disorders.
Mehta et al (15) reported severe metabolic acidosis, bradyarrhythmias
and renal failure in an 18-month-old child with arthrogryposis after a 5-hour propofol infusion while Burow et al (16) reported the development of acidosis following a 395 minute infusion of propofol in a 31-year-old woman.
that led to a requirement for pacemaker implantation occurred in 3 (1%) Iclusig-treated patients.
Monitor ECG in patients with congenital long QT syndrome, CHF, bradyarrhythmias
, or patients taking drugs known to prolong the QT interval.
Therefore, ICDs play an important role in reducing the risk of death from ventricular arrhythmias and bradyarrhythmias
These developments particularly contributed to advancement of treatment of cardiac bradyarrhythmias
and pacemaker therapy.
, and PR prolongation have all, however, been associated with reduced internal body temperature in humans, particularly in hypothermia (de Souza et al.
Additionally, because individuals with underlying heart conditions such as heart failure or bradyarrhythmias
and those predisposed to insufficient serum potassium and magnesium because of comorbid illness or other drugs are at particular risk, the FDA has made the following safety recommendations:
In the medical literature, if patients with bradyarrhythmias
are excluded from analysis of patients with a low heart rate, that is a flattening of the curve with no evidence of a J-shaped relationship (85), except possibly in patients presenting with an acute myocardial infarction (86).
Cardiovascular toxicity manifests as atrioventricular (AV) block, bradyarrhythmias
, asystole, ventricular fibrillation, hypotension, and ultimately cardiac arrest.
41) These bradyarrhythmias
occur even in the absence of any disease of the cardiac conduction system and often are eliminated by effective treatment of the OSA.
