If a patient experiences panic attacks and a conscious heartbeat like this, it is considered that this similar discomfort may be due to the presence of a disorder in the regulation of the patient’s plant nervous system or the presence of neurasthenia in the patient. Especially when the patient is uncomfortable and the ECG does not reveal any abnormality, it is highly considered to be caused by psychosomatic factors. Some menopausal women, or patients with anxiety, are relatively prone to this performance, and some patients may suffer from anemia or hypokalemia, hyperthyroidism, hypothyroidism, heart failure, or acute myocardial ischemia, which can also trigger this feeling of heartburn and heartbeat. Patients are advised to have routine blood tests, serum ions, thyroid function, and also an ambulatory electrocardiogram, if necessary, to help clarify the cause of the panic and heartbeat.
