Palpitations are a common symptom, a discomforting sensation that people experience with the beating of the heart. Clinically palpitation itself is not significant, and it is necessary to identify its causes, mainly arrhythmia, hyperthyroidism, anemia, cardiac neurosis, hypoglycemia, menopausal syndrome and so on. 1. Arrhythmia (1) Atrial fibrillation: it mostly occurs on the basis of organic heart disease, and is characterized by completely irregular heart rhythm, absolute discrepancy between heart rate and pulse rate, more heart rate than pulse rate, and unequal heart sound and pulse strength. (2) Paroxysmal tachycardia: it is characterized by sudden onset, sudden termination, and rapid but uniform heart rate. (2) Hyperthyroidism: due to increased basal metabolic rate and coexisting sympathetic hyperfunction, the heart rate is accelerated and the heart beat is strengthened. 3. Anemia: Anemia of various causes, when there are obvious compensatory changes in blood circulation, the patient will have palpitations. 4. Cardiac neurosis: it is the most common cause of palpitation. Patients may have annoying palpitations, mostly seen in young and middle-aged women, often accompanied by symptoms of neurosis other than circulatory system, such as sensory hypersensitivity, insomnia, fatigue and other manifestations. 5. Hypoglycemia: Symptoms such as palpitation, panic, hunger, weakness, sweating and anxiety. Physical examination may find patients with pale eyelids, tachycardia and low blood pressure, most of which can be recovered by themselves. 6. Menopause Syndrome: Women have a series of endocrine and phytoneurological disorders before and after menopause due to the aging and shrinkage of the ovaries, and a variety of symptoms appear. Such as palpitations, insomnia, dizziness and so on. When palpitation is obvious, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
