If a patient frequently experiences insomnia, trembling hands, and palpitations, it is possible that these symptoms are caused by myocardial ischemia. It is recommended that the patient actively undergo treatment using medications that dilate blood vessels and improve circulation, and firstly, coronary heart disease should be ruled out.

If a person has long-term sleep disorders, they can also develop a certain level of anxiety, which in turn can lead to insufficient coronary artery blood supply and thus myocardial ischemia. This condition can also manifest as palpitations and trembling hands.

Another scenario is hypoglycemia. If blood sugar levels are too low, symptoms such as palpitations, chest tightness, and trembling hands can occur, typically at night. For such cases, it is also necessary to promptly monitor the patient's heart rate, blood pressure, and pulse changes, and the diet should primarily consist of high-quality protein.
