Szívverésérzések

Szívverésérzések, often translated as palpitations, refer to the subjective sensation of a rapid, irregular, or forceful heartbeat. These sensations can be felt in the chest, throat, or neck and are a common experience for many people. While often alarming, palpitations are usually benign and can be triggered by various factors.

Common causes of palpitations include physiological responses to stress, anxiety, or fear, which activate the body's fight-or-flight response, leading to increased heart rate. Physical exertion, such as strenuous exercise, can also cause temporary palpitations. Dietary factors such as caffeine, nicotine, and alcohol consumption are well-known triggers. Certain medications, including decongestants, asthma inhalers, and some antidepressants, can also induce palpitations as a side effect.

In some cases, palpitations can be a symptom of an underlying medical condition. These can include cardiac arrhythmias like atrial fibrillation or supraventricular tachycardia, where the heart's electrical system malfunctions, causing an abnormal rhythm. Other heart conditions, such as valve problems or heart failure, can also manifest as palpitations. Non-cardiac causes include thyroid disorders, anemia, fever, and electrolyte imbalances.

While most palpitations are not serious and resolve on their own, persistent or severe symptoms, especially when accompanied by chest pain, shortness of breath, dizziness, or fainting, warrant medical attention. A doctor can evaluate the palpitations through a physical examination, electrocardiogram (ECG), Holter monitor, or other diagnostic tests to determine the cause and recommend appropriate management.
