is a group of conditions in which the heartbeat is irregular, too fast, or too slow. A heart rate that is too fast –above 100 beats per minute in adults – is called tachycardia and a heart rate that is too slo
Types of arrhythmias include tachycardia, which is a regular acceleration of the heart rate; bradycardia, a regular slowing of the heart rate; and premature atrial or ventricular beats, which are extra contractions within otherwise normal heart rhythm. While occasional irregularities are normal, prolong...
the patient might suffer dizziness or fainting spells due to the overly long pauses between heart contractions. Often, the combination of beta-blockers with a cocktail of other heart rate management drugs triggers the proarrhythmia. Therefore, many cardiologists are deciding against combination drug ...
Different types of cardiac arrhythmia are classified based on the morphology of the arrhythmic beats. Cardiac beats associated with an arrhythmic episode are compared to a plurality of representative beat morphologies, each representative beat morphology characterizing a type of arrhythmia of the heart....
An arrhythmia (also known as cardiac dysrhythmia) is defined as an irregular heartbeat, and results from abnormal electrical activity in the heart. There are various different types of arrhythmia, often resulting in a heartbeat that is too fast (tachycardia) or too slow (bradycardia). Atrial ...
Fig. 1.miRs regulate cardiac electrophysiology and heart rhythm through two different mechanisms: canonical posttranscriptional RNAi mechanism to regulate the expression of ion channels, which needs hours to days to take effect, and the biophysical modulation to directly and quickly (seconds to minutes...
What are the types of cardiac arrhythmia? Cardiac arrhythmias can be grouped by where they start in your heart. Ventricular arrhythmias occur in the lower chambers, while supraventricular arrhythmias begin in the upper chambers. They can also be grouped by their effect on your resting heart rate....
Arrhythmia, variation from the normal rate or regularity of the heartbeat, usually resulting from irregularities within the conduction system of the heart. Arrhythmias occur in both normal and diseased hearts and have no medical significance in and of th
