What's with the sudden palpitations?

Sudden palpitations may be related to factors such as bad diet, drug effects, heart diseases, etc.

1. Bad diet, such

as overeating spicy stimulating foods or stimulating drinks such as strong tea, coffee, alcohol, etc., can stimulate vascular nerves, affect human blood circulation, increase heart load, thus causing palpitations.

2. Drug effects, such

as calcium channel blockers, vasodilators, anticholinergic drugs, etc., can reduce peripheral vascular resistance, leading to relative blood volume reduction, thus causing myocardial ischemia, hypoxia, and palpitations.

3. Heart diseases, such

as hypertensive heart disease, mitral valve insufficiency, ventricular tachycardia, coronary heart disease, etc., can affect cardiac function, leading to increased heart load and reduced blood supply, thus causing palpitations.
