What causes palpitations and anxiety after sexual intercourse?

Palpitations and tachycardia after sexual intercourse may be caused by multiple factors, mainly including: 1. Sympathetic nerve excitation: During sexual activity, increased sympathetic nerve activity leads to elevated adrenaline secretion, causing rapid heartbeat and possible palpitations or tachycardia. These symptoms typically subside gradually within a few minutes. 2. Excessive fatigue: If sexual activity lasts too long or involves excessive physical strain, it may lead to overconsumption of physical energy and increased cardiac workload, thereby causing palpitations and tachycardia. 3. Cardiovascular diseases: Conditions such as heart disease, hypertension, and coronary artery atherosclerosis can impair the heart's blood supply and pumping function, leading to exacerbated symptoms of palpitations and tachycardia after sexual intercourse. 4. Hypoglycemia: Sexual activity consumes body glucose. If dietary intake is inadequate or excessive dieting occurs, blood glucose levels may drop, potentially triggering symptoms such as palpitations and tachycardia. 5. Myocarditis: Inflammatory lesions of the myocardium may also cause palpitations and tachycardia after sexual intercourse, with possibly more pronounced symptoms. 6. Psychological stress and anxiety: Sexual activity may induce psychological pressure and anxiety, which can also lead to symptoms such as palpitations and tachycardia. If symptoms of palpitations and tachycardia after sexual intercourse persist or occur frequently, timely medical consultation is recommended for relevant examinations to determine the underlying cause, and targeted treatment should be conducted under a physician's guidance.
