When to Worry About Heart Palpitations
Though palpitations are common, and many are not dangerous, new or changing heart palpitations warrant medical evaluation. This evaluation aims to rule out life-threatening arrhythmias (abnormal heart rhythms) or other health conditions that require monitoring or treatment.
What You Need to Know About Abnormal Heart Rhythm
An abnormal heart rhythm, or arrhythmia (also referred to as an irregular heartbeat), is a condition in which your heart beats too fast (at more than 100 beats per minute, or BPM), too slowly (at less than 60 BPM), or irregularly.
What Happens in Atrial Flutter?
Atrial flutter is a form of cardiac arrhythmia, a group of heart conditions characterized by an abnormal heart rhythm. With atrial flutter, you would experience tachycardia (a fast heart rate) with occasional palpitations (skipped beats).
What Is Sudden Cardiac Arrest?
Sudden cardiac arrest is an abrupt loss of heart function that leads a person to suddenly collapse, lose consciousness, and stop breathing. The heart stops beating and blood stops flowing to the brain and other vital organs.
What Are Heart Palpitations?
Heart palpitations are noticeable changes in the way the heart beats. They are not a disease or condition, but rather a symptom of one. Most people with palpitations have some type of cardiac arrhythmia (irregular heartbeat). While most arrhythmias are not life-threatening, some can indicate a serious heart problem.
