Most people don’t notice their heart beating since it’s such a subtle sensation. However, sometimes your heart may feel like it’s fluttering in your chest. For some, the feeling is almost electrical, as if a device is vibrating in your chest. Such sensations have several causes, many of which are infrequent and harmless, although some may require medical attention.
For those with serious conditions causing their heart palpitations, your doctor may recommend cardiac rehabilitation. Treatment often includes exercises to strengthen your heart. Lifestyle changes and nutrition education may repair the damage and reduce the risk of further complications. For more information on what’s causing your chest vibrations, keep reading.
Fluttering or Vibrating Heart Symptoms and Causes
Those odd vibrations in your heart are also called palpitations. According to medical professionals, they occur when your heart isn’t beating at its regular pace 1. It may be beating too fast, too slow, or irregularly, sometimes for several minutes. In addition to your chest, you may feel those beats in your neck and throat. We’ll discuss the symptoms and possible causes in the following sections.
Symptoms
A fluttering heart may sound gentle, almost like a butterfly flapping its wings. However, the actual symptoms aren’t so relaxing. Heart palpitations can be concerning and include various symptoms to watch for.
According to experts, in addition to that fluttery sensation, your heart may feel like it’s racing or pounding 2. It may miss a beat or have extras, creating an irregular rhythm. Some people even experience flip-flopping.
These professionals also mention that these symptoms are common and usually short-lived. But if the vibrations last longer than a few minutes or happen frequently, seek medical attention.
Experts also say that other symptoms may occur if circulation is affected, preventing blood from reaching the brain 3. These include dizziness, light-headedness, blurred or tunnel vision, nausea, confusion, or fainting. Although less common, report these symptoms to your doctor as soon as possible.
Causes
One possible cause of a fluttering heart is menopause. During this stage of life, estrogen and progesterone levels rise and fall 4. These erratic hormonal fluctuations may disrupt your heart’s normal pattern.
Stress or anxiety may also cause a vibrating sensation in your chest. According to medical professionals, these emotional moments trigger the release of adrenaline 5. This hormone speeds up your heart rate and breathing, which could cause an irregular heart rate.
Like the other muscles in your body, the heart needs exercise to stay strong and healthy 6. When you’re inactive for long periods or living a sedentary lifestyle, your heart suffers. As it weakens, it can’t pump blood as efficiently, which may result in heart fluttering.
Experts state that what you eat may cause your heart to pound, race, or skip a beat 7. This often happens when blood flow is redirected to the digestive system for food processing, or when blood pressure rises. Eating foods high in sugar, carbohydrates, sodium, saturated fat, or capsaicin may cause palpitations.
What you drink affects your heart. Researchers found that study participants experienced palpitations 54% more often on coffee-drinking days due to caffeine levels 8. Regular alcohol consumption is also responsible for irregular heart rates or fluttering, even when consumed in smaller amounts 9.
