Atrial arrhythmias are irregular heartbeats that cause poor circulation. They occur when the upper chambers of your heart are out of rhythm with the lower chambers. This can cause your heart to beat either too fast or slow.

2021年11月8日 · Atrial rhythms are classified as: Irritable sites in the atria fire very rapidly, between 400-600 bpm. This very rapid pacemaking causes the atria to quiver. The ventricles beat at a slower rate due to the AV node's blocking some of …

2023年3月20日 · An arrhythmia (also called dysrhythmia) is an abnormal heartbeat. Arrhythmias can start in different parts of your heart and they can be too fast, too slow or just irregular.

2021年3月9日 · When someone has an arrhythmia or dysrhythmia, their heartbeat has an abnormal rate or rhythm. Below, we’ll take a closer look at the terms arrhythmia and dysrhythmia. We’ll also explore...

2024年10月10日 · Arrhythmias can produce a broad range of symptoms and results. Your experience with arrhythmia may also differ depending on the type. For instance, a single premature beat may be felt as a “palpitation” or a “skipped beat.”

2024年5月19日 · Common atrial arrhythmias include premature atrial contractions, atrial fibrillation, and atrial flutter. Characteristics and treatment of common atrial dysrhythmias are summarized in Table 7.4b at the end of this subsection.

2014年12月10日 · Several kinds of abnormal heart rhythm (arrhythmia) occur in the heart's upper chambers (the atria). These include atrial fibrillation, atrial flutter, atrial tachycardia, and paroxysmal atrial tachycardia or paroxysmal supraventricular tachycardia. Atrial fibrillation is a common heart rhythm disturbance. More than 2.5 million Americans have it.

2022年5月9日 · A cardiac dysrhythmia (also called arrhythmia) is an abnormal or irregular heartbeat. An abnormal heart rate means that your heart rate is either too fast (typically over 100 beats per minute) or too slow (typically below 60 beats per minute).

Any heart disorder, including congenital abnormalities of structure (eg, accessory atrioventricular connection) or function (eg, hereditary ion channelopathies), can disturb rhythm.

2023年6月5日 · Arrhythmia is an abnormal rhythm of the heart. The only normal rhythm of the heart is a normal sinus rhythm. In this rhythm, an impulse is generated in the sinoatrial (SA) node, which is conducted through and slowed down while …
