A heart arrhythmia (uh-RITH-me-uh) is an irregular heartbeat. A heart arrhythmia occurs when the electrical signals that tell the heart to beat don't work properly. The heart may beat too fast or too slow. Or the pattern of the heartbeat may be inconsistent. A heart arrhythmia may feel like a fluttering, pounding or racing heartbeat.
Normal sinus rhythm is defined as the rhythm of a healthy heart. It means the electrical pulse from your sinus node is being properly transmitted throughout the heart muscle. In adults, normal...
Our heart rate adapts to our body’s need for energy throughout the day, whether it’s for walking up the stairs or a bout of strenuous exercise. These tempo changes based on physical activity are perfectly normal. Other common situations can trigger changes in heart rhythms too.
An abnormal heart rhythm is when your heart beats too fast, too slow, or irregularly. It’s also called an arrhythmia. Your heart contains a complex system of valves, nodes, and...
The American Heart Association explains that arrhythmia refers to any problem in the rate and/or rhythm of a person’s heartbeat, such as atrial fibrillation, bradycardia, tachycardia, conduction disorders, rhythm disorders, ventricular fibrillation, premature contractions and more.
An arrhythmia is a heart rhythm that isn’t normal. Your heart may be beating too fast when you’re at rest or just not beating in a regular pattern, for example. Arrhythmias range from harmless to serious, with symptoms and without.
The term “arrhythmia” refers to any problem in the rate and/or rhythm of a person’s heartbeat. During an arrhythmia, changes in heart tissue and activity, or in the heart’s electrical impulses, may cause the heartbeat to be too fast, too slow or erratic.
Fluttering and heart palpitations are telltale signs of arrhythmia, including AFib. Other serious heart problems, such as heart attack, have similar warning signs. A heart attack occurs when blood flow to the heart is blocked. This denies oxygen to the heart muscle — possibly damaging or destroying organ tissue.
The rhythm of the heart is normally controlled by its natural pacemaker (the sinus node), which produces electrical impulses that create the heartbeat. A normal, healthy heart beats about 60 to 100 times per minute, depending on what a person is doing.
What is an Arrhythmia? The term “arrhythmia” refers to any problem in the rate or rhythm of a person’s heartbeat. During an arrhythmia, the electrical impulses may be too fast, too slow or erratic, causing an irregular heartbeat. When the heart doesn’t beat properly, it can’t pump blood effectively.
