Can Dehydration Cause Heart Palpitations and Racing Heart Rate?
When the body loses too much water, the volume of blood traveling throughout the body decreases, and blood pressure lowers. When blood pressure lowers, a person's heart beats faster to ensure oxygen-rich blood reaches vital organs like the brain and kidneys.
What You Need to Know About Massive Heart Attacks
All heart attacks are serious, but a massive heart attack can be particularly deadly. A massive heart attack occurs when one of your arteries is blocked, disrupting oxygen flow to the heart. The most serious type of heart attack is an ST-segment elevation myocardial infarction (STEMI).
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).
