Inappropriate sinus tachycardia, defined as 24-hour average HR > 90 bpm and HR > 100 bpm in a supine or sitting position, has a prevalence of 1.16% in the general population. [20] The epidemiology of Inappropriate sinus tachycardia is not well understood. IST can occur at any age, but it is most common in adolescents and young adults. [2]
Ivabradine’s most frequent application in electrophysiology is for the treatment of inappropriate sinus tachycardia. Its use for inappropriate sinus tachycardia is not a European Medicines Agency or Food and Drug Administration approved indication for ivabradine. [10] It has been used experimentally for the treatment of postural orthostatic ...
In inappropriate sinus tachycardia (also known as chronic nonparoxysmal sinus tachycardia), patients have an elevated resting heart rate and/or exaggerated heart rate in response to exercise. These patients have no apparent heart disease or other causes of sinus tachycardia. IST is thought to be due to abnormal autonomic control.
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents.
Sinus node dysfunction (SND), also known as sick sinus syndrome (SSS), is a group of abnormal heart rhythms (arrhythmias) usually caused by a malfunction of the sinus node, the heart's primary pacemaker. [1] [2] Tachycardia-bradycardia syndrome is a variant of sick sinus syndrome in which the arrhythmia alternates between fast and slow heart ...
Each year, one out of every four Americans 65 years of age and older falls, leading to millions of emergency room visits and 1 million fall-related hospitalizations 3 ways to minimize your own ...
An automatic tachycardia is a cardiac arrhythmia which involves an area of the heart generating an abnormally fast rhythm, sometimes also called enhanced automaticity.These tachycardias, or fast heart rhythms, differ from reentrant tachycardias (AVRT and AVNRT) in which there is an abnormal electrical pathway which gives rise to the pathology.
Starting Jan. 1, millions of Americans who get their prescription drugs through Medicare could get a major financial break when a $2,000 out-of-pocket spending cap on medications goes into effect.
