What causes a fast heartbeat?

Introduction
Tachycardia, also known as rapid heart rate, may be caused by intense exercise, emotional excitement, anemia, hyperthyroidism, atrial fibrillation, or other factors. Engaging appropriately in physical activities such as jogging and swimming—forms of aerobic exercise—can help strengthen heart function. Maintaining a nutritionally balanced diet and avoiding excessive intake of high-fat and high-sodium foods is also recommended.

Generally, rapid heartbeat refers to an abnormally fast heart rate, which may be caused by intense exercise, emotional excitement, anemia, hyperthyroidism, atrial fibrillation, and other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analysis is as follows:

1. Intense Exercise

During intense physical activity, the body requires more oxygen and nutrients. The heart increases its rate to boost blood flow and meet the heightened demands of muscles and tissues, resulting in a faster heart rate. To manage this, avoid strenuous exercise, gradually reduce exercise intensity, and engage in appropriate relaxation and stretching activities to help restore normal heart rate.

2. Emotional Excitement

When emotionally excited, the brain releases hormones such as adrenaline and noradrenaline, which act on the heart to enhance its contractility, thereby increasing heart rate. Deep breathing, meditation, or light physical activities like walking can help calm emotions and lower heart rate.

3. Anemia

Anemia results from factors such as malnutrition or insufficient red blood cell supply. In anemia, the reduced number of oxygen-carrying red blood cells forces the heart to increase both pumping volume and rate to compensate for inadequate oxygen delivery, leading to tachycardia. Symptoms may include fatigue and pallor. It is recommended to follow medical advice and use medications such as ferrous sulfate tablets, compound ammonium ferric citrate syrup, or ferrous fumarate tablets for treatment.

4. Hyperthyroidism

Hyperthyroidism can be triggered by excessive iodine intake, anxiety, and other factors. When the thyroid gland is overactive, excess thyroid hormones stimulate the heart to beat faster in order to meet the body’s increased metabolic demands, causing tachycardia. Symptoms may also include hand tremors and excessive sweating. Under the guidance of a healthcare professional, medications such as Jiaxingling tablets, propylthiouracil tablets, or methimazole tablets may be used for treatment.

5. Atrial Fibrillation

Atrial fibrillation is primarily caused by excessive fatigue, aging, and similar factors. In atrial fibrillation, abnormal electrical activity in the atria generates multiple irregular impulses, causing the ventricles to respond with rapid contractions, significantly increasing heart rate. Symptoms may include palpitations and chest tightness. Treatment should follow medical advice and may include medications such as enteric-coated aspirin tablets, clopidogrel hydrogen sulfate tablets, or diltiazem hydrochloride tablets.

Maintain a nutritionally balanced diet and avoid consuming excessive high-fat and high-sodium foods.

Can anxiety cause an increased heart rate?
Anxiety disorder can cause an increased heart rate, which is one of its common physical symptoms resulting from nervous and endocrine system disturbances triggered by anxiety. It may also be accompanied by other physical discomforts. If rapid heartbeat occurs frequently, lasts for prolonged periods, or is accompanied by symptoms such as chest pain or dizziness, prompt medical attention is recommended. During an anxiety attack, the sympathetic nervous system becomes abnormally excited.

Is a heart rate of 120 beats per minute during anxiety dangerous?
In general, whether a heart rate of 120 beats per minute in individuals with anxiety disorder is dangerous depends on specific symptoms and individual health status. It usually isn't directly dangerous if no other symptoms are present; however, risks may exist if accompanied by chest pain, shortness of breath, or if the elevated heart rate persists for a prolonged period. Daily prevention of anxiety episodes can include techniques such as progressive muscle relaxation and listening to calming music.

What is the relationship between luteinizing hormone and progesterone?
Under normal circumstances, luteinizing hormone (LH) promotes the formation and maturation of the corpus luteum in the ovary, and the corpus luteum is the primary tissue responsible for progesterone secretion. These two elements are interdependent and regulated within the female reproductive cycle. If there are any concerns, it is recommended to seek medical advice early. In a normal menstrual cycle, luteinizing hormone levels peak before ovulation, triggering follicular rupture and egg release; afterward, the ruptured follicle develops into the corpus luteum.

Is it useful to check sex hormones if menstruation is absent?
If menstruation is absent and pregnancy has been ruled out, and symptoms such as long-term menstrual irregularity, hirsutism, acne, hot flashes, and night sweats are present, the condition is likely related to endocrine disorders. At this point, testing sex hormones (such as estrogen, progesterone, testosterone, etc.) can accurately determine whether hormone levels are abnormal, helping to identify conditions such as polycystic ovary syndrome, hyperprolactinemia, or ovarian insufficiency.

Is a fetal heart rate of 165 during NT scan normal?
A fetal heart rate of 165 beats per minute during NT scan is generally normal. The normal fetal heart rate range in early to mid-pregnancy is 110–160 beats per minute. A rate of 165 bpm is slightly above the upper limit but often represents physiological variation and is usually not a cause for concern. However, if repeated measurements show a fetal heart rate persistently exceeding 180 beats per minute or below 110 beats per minute, medical evaluation is recommended.
