Heart palpitations can feel startling, especially when they happen out of nowhere. Heart palpitations are common, and many episodes are not linked to a serious condition. Still, certain patterns are worth checking, particularly when palpitations feel new, persistent, or come with other symptoms.
This article explains what heart palpitations may feel like, why they can happen, which features can make them more concerning, and what a check up typically involves.
Key Takeaways
Heart palpitations are common and often not serious, especially when brief
Everyday triggers like stress, caffeine, fatigue, or dehydration can cause them
The pattern and symptoms matter more than a single episode
Seek medical attention if they are persistent, worsening, or come with chest pain, breathlessness, or fainting
A check-up helps identify the cause and ensures your heart rhythm is properly assessed

Heart palpitations explained in plain terms
Heart palpitations are the sensation of becoming unusually aware of your heartbeat. Some people describe them as:
A racing heartbeat
A fluttering sensation
A pounding or thumping in the chest
A skipped or extra beat
A sudden flip in the chest
Palpitations can occur during stress or exertion, but they can also happen at rest, including when you are trying to fall asleep.
The sensation alone does not confirm a dangerous rhythm. Many palpitations are brief and relate to temporary factors such as stress hormones, caffeine, fatigue, dehydration, or anxiety. Because the heart’s electrical system is sensitive to internal changes, pattern and context often matter more than a single episode.
What heart palpitations can feel like day to day
Heart palpitations may:
Start and stop suddenly
Last a few seconds or several minutes
Feel irregular or unusually forceful
Occur during stress, after caffeine, or during illness
Show up when lying down or resting
Some people also notice dizziness, breathlessness, chest discomfort, or a sense of heightened alertness alongside palpitations.
A simple way to compare patterns, not a diagnosis
Brief skipped beats without other symptoms may be related to benign extra beats
Palpitations during stress or caffeine intake may reflect heightened stimulation
Sustained rapid heartbeat with dizziness or chest symptoms may warrant medical assessment
These are patterns rather than rules. Overlap is common.
When heart palpitations may be a concern
Heart palpitations may be more concerning when they:
Are new, persistent, or worsening
Last for a prolonged period or do not settle
Occur with fainting or near fainting
Are associated with chest pressure, shortness of breath, sweating, or marked weakness
Occur during minimal activity
Happen in the context of known heart disease
Checked sooner may be appropriate if palpitations are sustained, occur with fainting, come with chest symptoms or breathlessness, happen with exertion, or represent a clear change from your usual pattern.
These features do not confirm a serious condition on their own, but they are reasons to seek medical evaluation rather than relying on self assessment.
Not always serious: Common reasons for heart palpitations
Many episodes of heart palpitations are not due to a dangerous heart rhythm. Common non emergency contributors may include:
Stress or anxiety responses
Adrenaline release can temporarily increase heart rate or make the heartbeat feel more noticeable.
Caffeine or stimulants
Coffee, energy drinks, nicotine, and some medications can affect rhythm sensitivity.
Fatigue or dehydration
Sleep disruption and fluid or electrolyte shifts can increase extra beats.
Hormonal changes
Some individuals notice palpitations during menstrual cycle shifts or other hormonal transitions.
Even when palpitations are eventually found to be benign, new or changing patterns should still be assessed in the appropriate clinical context.
What a check up for heart palpitations usually involves
Evaluation typically begins with a structured symptom review. This may include:
What the palpitations feel like
How long they last and how often they occur
Triggers and relieving factors
Associated symptoms such as dizziness, chest discomfort, or breathlessness
Medication use and relevant lifestyle factors
Personal and family history
Depending on the presentation, further assessment may include:
Physical examination and pulse assessment
Electrocardiogram (ECG)
Ambulatory heart monitoring such as a Holter monitor
Blood tests
Further cardiac imaging where clinically appropriate
The specific approach depends on the individual pattern and overall risk profile.
Where The Sunrise Clinic may fit into next steps
If heart palpitations are persistent, changing, or difficult to interpret, The Sunrise Clinic may be one setting where symptoms can be assessed in clinical context and further evaluation considered where appropriate.
The purpose of review is to reduce uncertainty and help ensure symptoms are assessed in the right clinical context.
FAQ
What triggers heart palpitations
Heart palpitations are often triggered by everyday factors such as stress, anxiety, and increased adrenaline levels. Stimulants like caffeine, nicotine, and certain medications can also make the heartbeat feel faster or more noticeable. Physical factors such as fatigue, dehydration, and lack of sleep may contribute as well. In some cases, hormonal changes can play a role, especially during certain phases of the menstrual cycle.
When to go to the ER for palpitations?
You should seek emergency care if palpitations are accompanied by chest pain, shortness of breath, fainting, or severe dizziness. It is also important to go if the heartbeat is very fast, irregular, or does not settle with rest. Palpitations that occur during minimal activity or feel significantly different from usual episodes should not be ignored. These symptoms may indicate a more serious condition that requires prompt medical attention.
What helps heart palpitations immediately?
For mild palpitations, resting and sitting or lying down can help the body settle. Slow, deep breathing can reduce stress and calm the heart rate. Drinking water may help if dehydration is a contributing factor. Avoiding stimulants and giving your body time to recover often allows symptoms to pass.
Can asthma cause heart palpitations?
Yes, asthma can sometimes lead to heart palpitations, especially during episodes of breathlessness. The body may respond to difficulty breathing by increasing heart rate, which can feel like pounding or racing. Anxiety related to breathing discomfort can also contribute to this sensation. Additionally, some asthma medications, particularly reliever inhalers, may temporarily stimulate the heart.
