The main causes of heart palpitations are often benign, such as stress, anxiety, intense exercise, caffeine, dehydration, or hormonal changes (pregnancy/menopause), making them temporary awareness of a normal heartbeat. However, they can sometimes signal a more serious underlying issue like an arrhythmia (irregular heart rhythm), thyroid problems, anemia, or certain medications, requiring medical attention if persistent or accompanied by other symptoms like chest pain or fainting, say Healthdirect and Mayo Clinic.
Try relaxation techniques, such as meditation, yoga or deep breathing. Avoid stimulants. Caffeine, nicotine, some cold medicines and energy drinks can make the heart beat too fast or irregularly.
Common causes of heart palpitations include some lifestyle factors like:
Why do I cough when my heart flutters? A fluttery feeling can trigger the urge to cough. Coughing and an irregular heartbeat together may be symptoms of an upper respiratory infection or pneumonia. Also, a persistent dry cough can be a symptom of heart disease.
Worry about heart palpitations if they come with chest pain, severe shortness of breath, dizziness, fainting, or unusual sweating; also see a doctor if they are frequent, prolonged, worsening, or if you have existing heart issues, diabetes, high blood pressure, or thyroid problems, as these can signal serious conditions needing immediate care or evaluation.
You currently have heart palpitations with any of these symptoms: chest pain. shortness of breath. feeling faint or fainting.
Three early warning signs of heart failure include persistent fatigue/weakness, shortness of breath (especially with activity or lying down), and swelling in the legs, ankles, or feet (edema), which occur as the heart struggles to pump blood efficiently, leading to fluid buildup and reduced oxygen to tissues. Other signs are a rapid/irregular heartbeat, persistent cough (especially with pink/white mucus), and unexplained weight gain.
An arrhythmia is an abnormal heart rhythm, where the heart beats irregularly, too fast or too slowly. A palpitation is a short-lived feeling of your heart racing, fluttering, thumping or pounding in your chest.
Unlike a typical cough caused by a cold or allergies, cardiac cough may occur due to fluid buildup in the lungs when the heart is unable to pump effectively. Common symptoms associated with cardiac cough include persistent coughing, extreme fatigue, difficulty breathing, and other signs often overlooked.
They usually happen for only a short time and go away quickly. Most heart palpitations are temporary with no long-term effects and no particular cause. Some can be a sign of more serious heart conditions.
Heart palpitations (pal-pih-TAY-shuns) are feelings of having a fast-beating, fluttering or pounding heart. Stress, exercise, medication or, rarely, a medical condition can trigger them. Although heart palpitations can be worrisome, they're usually harmless.
Certain medications, such as asthma medication, thyroid pills and cold medicines, may also cause heart palpitations. While there are many causes of irregular heartbeats, heart palpitations are rarely serious.
As with other hormone imbalances, thyroid issues can cause a wide variety of symptoms. One of those symptoms is heart palpitations, which happen when you are aware of your heartbeat if it becomes fast-paced or irregular.
Feeling your heart race or flutter at night—especially when you're lying down—can be unsettling. While heart palpitations during sleep may seem alarming, they're often harmless and surprisingly common.
Call your provider right away if: You often feel extra heartbeats (more than 6 per minute or coming in groups of 3 or more). You have heart disease or risk factors for heart disease, such as high cholesterol, diabetes, or high blood pressure. You have new or different heart palpitations.
Myocarditis is inflammation of the heart muscle, usually following a virus. Some people have no symptoms, but it can cause chest pains, palpitations and shortness of breath.
Electrocardiogram. An electrocardiogram (ECG) is a test that records the electrical activity of the heart. The ECG reflects what's happening in different areas of the heart and helps identify any problems with the rhythm or rate of your heart. The ECG is painless and takes around 5-10 minutes to perform.
A cough from heart failure tends to be persistent and you might produce phlegm, which can be white, pink or blood-tinged. It might happen at night when you're lying down.
Symptoms of an Enlarged Heart: Early Warning Signs
But sometimes people mistake heart palpitations for a more serious condition called atrial fibrillation, or AFib. AFib occurs when rapid electrical signals cause the heart's two upper chambers to contract very fast and irregularly.
Worry about heart palpitations if they come with chest pain, severe shortness of breath, dizziness, fainting, or unusual sweating; also see a doctor if they are frequent, prolonged, worsening, or if you have existing heart issues, diabetes, high blood pressure, or thyroid problems, as these can signal serious conditions needing immediate care or evaluation.
Another vitamin deficiency that can lead to heart pal- pitations is vitamin B12. Similar to a folate deficiency, a lack of vitamin B12 can lead to anaemia and thereby result in heart palpitations, per the ODS. Vitamin D is another supplement that can cause heart palpitations when taken in large amounts.
Main symptoms
fatigue – you may feel tired most of the time and find exercise exhausting. swollen ankles and legs – this is caused by a build-up of fluid (oedema); it may be better in the morning and get worse later in the day. feeling lightheaded and fainting.
A change in symptoms is important to discuss with your health care professional. Some physical signs of heart valve disease can include: Chest pain or palpitations (rapid rhythms or skips) Shortness of breath, fatigue, weakness or inability to maintain regular activity level.
High cholesterol is often silent, but warning signs appear as plaque builds up, including chest pain (angina), shortness of breath, fatigue, numbness/coldness in limbs, dizziness, yellow fatty deposits (xanthomas), difficulty breathing, slurred speech, swelling in legs, or jaw/back pain (especially in women), often indicating a serious complication like a heart attack or stroke. A blood test (lipid profile) is the only way to know your levels.
