Sudden slow heartbeat nausea and vomiting at night may be a sign of variant angina, lowered blood pressure, or gastrointestinal disease.
1. Variable angina usually occurs at night when you are resting, with heart rate disorders such as increased speed and slowed down, and may be accompanied by gastrointestinal symptoms such as nausea and vomiting. Electrocardiogram (ECG) and 24-hour ambulatory electrocardiogram (EKG) can be performed at the nearest hospital.
2. Decreased blood pressure may cause insufficient gastrointestinal blood perfusion, leading to nausea and vomiting, and may also cause heart rate slowing. 24-hour ambulatory blood pressure monitoring can be done to monitor blood pressure changes at night.
3. Gastrointestinal diseases such as duodenal ulcer, epigastric pain, nausea, vomiting and other symptoms occur at night. At night, the vagus nerve is excited and the heart rate will drop. You can go to the nearest hospital for gastroscopy and diagnosis.
It is recommended to go to the relevant specialized department in the hospital.
