Sudden palpitations and anxiety may be caused by various factors, including the following possibilities:
1. Emotional factors: Abnormally intense emotions, stress, anxiety, and other mental stimuli may affect blood circulation and increase the workload on the heart, leading to symptoms of palpitations.
2. Heart diseases: Conditions such as myocarditis and angina pectoris may cause ischemia and hypoxia in myocardial cells, triggering symptoms such as palpitations and chest pain.
3. Arrhythmias: Including ventricular premature contractions and atrial premature contractions, which are common causes of palpitations and anxiety.
4. Endocrine system diseases: For example, hyperthyroidism, in which increased levels of thyroid hormones lead to an elevated heart rate, causing symptoms such as palpitations and anxiety.
5. Other factors: Conditions such as anemia, hypoglycemia, and electrolyte imbalances may also lead to symptoms of palpitations and anxiety.
When sudden palpitations or anxiety occur, it is recommended to seek medical attention promptly. The underlying cause should be identified through relevant examinations such as electrocardiogram (ECG) and echocardiography, followed by targeted treatment. Patients with concerns are advised to consult a healthcare professional promptly.
