As a healthcare professional with a background in cardiology, I can provide you with an informed perspective on the causes of heart palpitations. Heart palpitations are sensations of your heart beating hard or fast, skipping a beat, or fluttering. They can be triggered by a variety of factors, including: 1. Physical activity: Intense exercise can cause your heart to beat faster. 2. Caffeine, alcohol, and nicotine: These substances can stimulate the heart. 3. Stress and anxiety: Emotional stress can lead to palpitations. 4. Dehydration and electrolyte imbalances: These can affect heart rhythm. 5. Certain medications: Some drugs can cause heart palpitations as a side effect. 6. Underlying heart conditions: Problems such as mitral valve prolapse or heart rhythm disorders can cause palpitations. 7. Other medical conditions: Thyroid problems, anemia, or low blood sugar can also lead to palpitations. It's important to note that while most cases of heart palpitations are not serious, they can sometimes be a sign of an underlying health issue that requires medical attention. read more >>
