What causes sudden rapid heartbeat, palpitations, and high blood pressure, and what should I do?

Sudden rapid heartbeat, palpitations, and elevated blood pressure may be caused by psychological factors, sudden hypertension, hyperthyroidism, or other reasons. These symptoms can be improved through general management, medications, and other methods. A detailed analysis is as follows:

1. Psychological Factors

If work-related stress is high, leading to mental tension or depression, it may result in symptoms such as increased heart rate, palpitations, and elevated blood pressure. It is important to get adequate rest and avoid excessive fatigue.

2. Sudden Hypertension

Sudden hypertension refers to a sharp rise in blood pressure to very high levels, which may be triggered by abnormal adrenaline secretion, medication side effects, or hormonal changes. The sudden increase in blood pressure can lead to insufficient blood supply to the heart, causing symptoms like palpitations and rapid heartbeat. Patients may take medications such as Captopril tablets, Nifedipine tablets, or Nitroglycerin tablets under medical supervision.

3. Hyperthyroidism

Hyperthyroidism is a condition caused by excessive production of thyroid hormones by the thyroid gland. Thyroid hormones accelerate the body's metabolism, and overproduction can lead to symptoms such as rapid heartbeat and chest tightness. Patients may be treated with medications such as Propylthiouracil tablets or enteric-coated Propylthiouracil capsules under a doctor's guidance.

In addition to the above causes, similar symptoms may also result from hypotension, myocardial infarction, cerebral infarction, or other conditions. Given the variety of potential underlying causes, individuals experiencing discomfort should seek timely medical evaluation at a hospital.
