What to know about heart palpitations
Heart palpitations are sensations of a pounding or racing heartbeat, often triggered by stress, stimulants, or hormonal changes. They're usually harmless but should be checked by a doctor. Palpitations may improve with lifestyle changes or treatment for underlying conditions.
What is a bubble study?
Performed during an echocardiogram, a bubble study involves injecting a small amount of fluid filled with tiny bubbles into an arm vein. It can reveal the path of blood flow through the heart and provide clues about the cause of an unexpected stroke.
When should you worry about abnormal heartbeats?
People commonly experience heart palpitations, which feel like the heart flutters or skips a beat, or beats at a faster rate or in an irregular rhythm. They often last only seconds and can be unsettling. For the most part, palpitations are nothing to worry about. Still, these unusual heart sensations may indicate something more serious, such as atrial fibrillation, supraventricular tachycardia, or ventricular tachycardia. Palpitations that persist or cause other symptoms (such as lightheadedness) should be evaluated by a doctor.
