Heartbeat feels very heavy and fast when squatting down and standing up
Dizziness and rapid, forceful heartbeat upon standing up from a squatting position may result from non-disease factors such as physiological phenomena, or could be caused by medical conditions including anemia, hypoglycemia, and hyperlipidemia. Treatment options include medication and nutritional supplementation.
I. Non-Disease Factors
Physiological Phenomenon: Squatting can temporarily impede blood circulation, leading to a reduced cardiac output. To meet the body's normal oxygen demands, the heart compensates by beating faster and more forcefully, resulting in the sensation of a heavy, rapid heartbeat when rising from a squat. This is a normal physiological response and typically resolves spontaneously upon standing and resting.
II. Disease Factors
1. Anemia
Imbalanced diet, picky eating, or inadequate nutrient intake may lead to anemia, causing symptoms such as a heavy and rapid heartbeat when standing up from a squat, dizziness, and general weakness. Treatment may include medications such as ferrous sulfate tablets, Ejiao Blood-enriching Granules, or Yiqi Yangxue Oral Liquid, taken under medical guidance. Additionally, adjusting dietary habits and increasing nutritional intake are recommended.
2. Hypoglycemia
Hypoglycemia may occur due to genetic factors, excessive dieting, or irregular eating patterns, resulting in abnormally low blood glucose levels. Symptoms include a pounding, rapid heartbeat upon standing, tremors, and even fainting. Treatment may involve medically supervised use of medications such as glucose injection, hydrochlorothiazide tablets, or hydrocortisone tablets.
3. Hyperlipidemia
Elevated lipid levels can also cause a heavy, rapid heartbeat when rising from a squat. Active treatment with lipid-lowering medications is recommended. Commonly used drugs include statins such as rosuvastatin and atorvastatin, and fibrates such as fenofibrate, selected based on the patient’s specific lipid profile.
Other possible causes of a heavy heartbeat upon standing from a squat include orthostatic hypotension, coronary atherosclerotic heart disease, and viral myocarditis. It is advisable to seek timely medical evaluation at a hospital, including diagnostic tests such as X-ray or MRI, to confirm the diagnosis and receive appropriate treatment.
