What Does It Mean When Your Heart Beats Fast for No Reason?
A fast heart rate without an obvious cause often indicates palpitations, which can stem from various factors. Common triggers include caffeine consumption, stress, dehydration, lack of sleep, or hormonal changes. Medical conditions like hyperthyroidism, anemia, or heart rhythm disorders can also cause unexplained rapid heartbeat. Normal resting heart rate ranges from 60-100 beats per minute, but palpitations can push it above 100 bpm. While occasional episodes are usually harmless, frequent or concerning symptoms warrant medical evaluation. Keeping a symptom diary noting triggers, duration, and associated symptoms helps healthcare providers determine the underlying cause and appropriate treatment approach.
