Heart rate and blood pressure are both normal, but I feel palpitations. What could be the cause, and what should I do?

Normal heart rate and blood pressure, but feeling palpitations, may be caused by physiological factors or pathological conditions such as cardiac neurosis or arrhythmia. Treatment can include general lifestyle management or medication, depending on the specific situation. Details are as follows:

I. Physiological Factors

If a patient frequently smokes or consumes excessive coffee, the heart may be stimulated by caffeine or nicotine, leading to the aforementioned symptoms. Special medical treatment is usually unnecessary. It is recommended to adjust the diet, focusing on light and easily digestible foods, and to quit smoking and avoid caffeine.

II. Pathological Factors

1. Cardiac Neurosis

When exposed to external stressors or under significant psychological pressure, dysfunction of the sympathetic and parasympathetic nervous systems may occur, causing symptoms such as palpitations, shortness of breath, and chest pain. Medications such as nifedipine tablets or nitroglycerin tablets may be used according to medical advice.

2. Arrhythmia

This is primarily caused by abnormalities in the origin, activity, or conduction of cardiac electrical impulses, resulting in irregular heart rate or rhythm, accompanied by symptoms like palpitations and restlessness. Treatment may include medications such as propafenone hydrochloride tablets or propranolol hydrochloride tablets, taken under a doctor's guidance.

In addition to the above causes, palpitations may also result from anemia, hyperthyroidism, coronary atherosclerotic heart disease, heart failure, or chronic obstructive pulmonary disease. Adequate rest and avoidance of excessive fatigue are recommended.
