Have you ever felt your heart suddenly flutter, race, skip a beat, or pound harder than usual? These sensations, known as heart palpitations, are surprisingly common and can happen to people of all ages.
While many palpitations are harmless and temporary, others may signal an underlying heart rhythm disorder or another medical condition that requires evaluation. Understanding what heart palpitations feel like, what causes them, and when to seek medical care can help you protect your heart health and gain peace of mind.
Heart palpitations are the sensation of being unusually aware of your heartbeat. Some people describe them as:
Palpitations may occur during activity, while resting, or even when lying in bed at night. They can last for a few seconds or continue for several minutes or longer.
In many cases, palpitations are not dangerous. However, because they can sometimes be linked to heart rhythm abnormalities, it is important not to ignore persistent or concerning symptoms.
There are many reasons why a person may experience heart palpitations. Some are related to lifestyle factors, while others may involve medical conditions.
When the body experiences stress, it releases hormones such as adrenaline that can increase heart rate and create sensations of fluttering or pounding in the chest.
Emotional stress, anxiety, panic attacks, and even excitement can trigger palpitations in otherwise healthy individuals.
Coffee, tea, energy drinks, certain supplements, and some over-the-counter medications can stimulate the heart and contribute to palpitations.
Each person’s sensitivity varies. Some individuals may notice symptoms after only a small amount of caffeine.
When the body becomes dehydrated, blood volume decreases and the heart may work harder to maintain circulation. This can sometimes lead to palpitations, dizziness, or fatigue.
Poor sleep or sleep deprivation can affect hormone levels, increase stress responses, and make palpitations more likely.
Some medications may contribute to palpitations, including:
If you notice symptoms after starting a new medication, discuss your concerns with your healthcare provider.
Hormonal fluctuations during pregnancy, menopause, or certain thyroid disorders may contribute to irregular heart sensations.
In some cases, palpitations may be caused by an arrhythmia, which is an abnormal heart rhythm.
Examples include:
Some arrhythmias are relatively benign, while others require treatment to reduce complications such as stroke, heart failure, or other cardiovascular issues.
Heart palpitations can occur alone or alongside other symptoms.
You should pay particular attention if palpitations occur with:
These symptoms may suggest that the heart is not pumping efficiently and warrant prompt medical evaluation.
Many occasional palpitations are harmless. However, it is important to schedule an evaluation if:
When in doubt, it is always better to err on the side of caution and seek medical attention.
One challenge with palpitations is that they may come and go. A patient may feel perfectly normal during an office visit even though symptoms occur at other times.
Fortunately, modern cardiovascular testing can help identify the cause.
A cardiologist may recommend:
An ECG records the heart’s electrical activity and can identify many rhythm abnormalities.
Portable monitors, such as Holter monitors and event monitors, allow providers to evaluate heart rhythms over days or weeks while patients continue their normal activities.
An echocardiogram uses ultrasound technology to evaluate heart structure and function.
Exercise stress testing may help determine whether symptoms are triggered by physical activity or reveal underlying cardiovascular disease.
Additional testing may be recommended depending on symptoms, medical history, and initial findings.
Treatment depends on the underlying cause.
For some patients, simple lifestyle changes may significantly reduce symptoms.
These may include:
For patients with diagnosed arrhythmias or other heart conditions, treatment may involve medications, specialized monitoring, electrophysiology evaluation, or other advanced cardiac interventions.
The most important step is obtaining an accurate diagnosis so treatment can be tailored to your specific needs.
