What Do Heart Palpitations Feel Like?
Updated April 14, 2025
Heart palpitations are a general category for any time your heartbeats don’t feel healthy or normal. Although they can be scary, especially the first time you experience them, heart palpitations aren’t usually a cause for concern. If you experience them frequently or have a personal or family history of heart problems, you should contact a cardiologist.
What Heart Palpitations Feel Like
People describe heart palpitations in many ways. People often describe heart palpitations as a heartbeat that is:
- Pounding
- Fluttering
- Irregular
- Flip-flopping
- Beating too fast
- Skipping beats
- Having extra beats
In addition to feeling them in your chest, you might feel them in the throat or neck, sometimes even in the head.
What Are Heart Palpitations
Heart palpitations are a subjective symptom: they’re defined by the way you feel about your heartbeat. You could be having heart palpitations if you notice any of the heartbeat feelings listed above. They might be actual irregularities in your heartbeat, or they might be a perception that your heart is beating irregularly, even if it’s not.
The only way to tell the difference – and determine if any irregular heartbeat is a cause for concern – is with heart monitoring.
What Causes Heart Palpitations
There are many potential causes of heart palpitations. Most are not serious. Some of these you can control, while others are beyond your control. Possible causes of heart palpitations include:
- Heart conditions
- Low blood sugar
- Strenuous exercise
- Stress, anxiety, or panic attacks
- Stimulants, such as:
- Caffeine
- Nicotine
- Cocaine
- Amphetamines
- Pseudoephedrine
- Opioids like heroin and fentanyl
- Other medications
- Alcohol
- Illness and fever
- Hormone changes linked to menstruation, pregnancy, or menopause
- Thyroid hormone shortage or deficit
- Certain foods
Heart conditions associated with heart palpitations include heart arrhythmias like atrial fibrillation, atrial flutter, and some types of tachycardia. Structural heart problems and heart failure can also cause heart palpitations. When palpitations occur frequently, you should see a cardiologist to rule out these types of heart conditions.
When Should I Worry About Heart Palpitations?
In most situations, heart palpitations are harmless. This is generally the case when they’re caused by factors such as stress, caffeine, exercise or hormonal changes. It’s not always necessary to seek care for short, occasional heart palpitations. However, you should seek emergency care if you also experience:
- Pain or discomfort in your chest, arm, or jaw
- Shortness of breath
- Dizziness
- Fainting
You should consult with a cardiologist if:
- Heart palpitations occur frequently, last longer than usual, or involve more than six beats per minute
- Heart palpitations worsen
- You have a personal or family history of heart disease
- You have risk factors such as obesity, smoking or high cholesterol which might indicate that your heart palpitations are a sign of underlying heart problems
- You notice a sudden change in the frequency or intensity of heart palpitations
Your cardiologist may recommend monitoring to learn more about what’s causing your palpitations.
Lifestyle Changes Can Help Reduce or Prevent Heart Palpitations
In many instances, making certain lifestyle changes can help to reduce or prevent heart palpitations. Getting regular cardiovascular exercise is a great way to strengthen your heart and reduce palpitations. Aim for 150 minutes of moderate aerobic exercise each week; however, avoid activities that typically worsen your symptoms. In addition, practicing relaxation techniques such as yoga, medication and deep breathing can help reduce stress-induced heart palpitations.
Making dietary adjustments is one of the most impactful steps you can take to reduce heart palpitations:
- Eat a heart healthy diet containing plenty of fruits, vegetables, whole grains, lean proteins and healthy fats. Avoid processed foods, as well as foods containing excessive levels of salt, sugar and unhealthy fats.
- Identify trigger foods that tend to cause you to develop heart palpitations.
- If you’re diabetic, adjust your diet to more effectively manage your blood sugar levels.
Other lifestyle adjustments you can make include:
- Getting more sleep each night (aim for 7-9 hours a night)
- Limiting alcohol intake
- Reducing your consumption of stimulants such as caffeine
- Quitting smoking
It’s also a good idea to keep a journal of the activities, foods, medications and emotional states that typically trigger heart palpitations. This can help you understand which lifestyle adjustments will have the greatest impact on reducing the frequency of your palpitations.
