Coffee contains more caffeine, which has a certain possibility of stimulating cardiovascular diseases and more excitatory effects on sympathetic nerves. After drinking coffee, the heart rate may increase and the patient may experience panic attacks. People who have arrhythmias may also have arrhythmias after drinking coffee. If you have a panic attack after drinking coffee, you must pay attention to measuring your pulse rate. If the pulse is uneven or above 140 beats/min, you must pay attention to the possibility of arrhythmia, and it is recommended to improve the electrocardiogram examination. After a similar situation, usually refuse to drink coffee or strong tea, and do not drink drinks that tend to cause sympathetic excitement.
