More Heart Rhythm Disorders Overview
Arrhythmias arising in the ventricle (ventricular arrhythmias) are more likely to be found in people with more serious heart disease but may also be found in healthy individuals.
Bradyarrhythmias produce heart rates that are too slow to allow enough blood to be pumped during either time of demand (stress or increased activity) or even during normal activity. Bradyarrhythmias are usually slower than 60 beats per minute. For example, patients may become dizzy and pass out when they try to stand up because not enough blood is pumped into the brain.
Arrhythmias can be frightening, but in many cases, especially in younger patients with normal underlying hearts, they are not life-threatening and can be effectively treated with medications.
The purpose of this article is to give the reader an introduction to heart rhythm disorders. Each disorder or arrhythmia has been studied in great detail by many investigators so there are books and articles devoted to each type of arrhythmia. The reader is advised to click onto the references for more detail on each type of arrhythmia for more in depth details about diagnosis, treatments, and outcomes. Specific details for each type and subtype of disorder are far beyond the scope of this introductory article.
