The causes of episodes of panic and throbbing sensation in the chest are more common, and the common causes are cardiac arrhythmias and myocardial ischemia in patients with coronary artery disease. Rapid arrhythmias, such as premature beats in different parts of the heart, supraventricular tachycardia, atrial fibrillation, and so on. Taking premature beats as an example, such as atrial premature beats, ventricular premature beats, etc., patients may experience a feeling of heart stopping for a few seconds after resting or activities, like atrial fibrillation and supraventricular tachycardia also have similar symptoms. Some patients with coronary artery disease who have angina attacks may only show symptoms of palpitations, most of which are episodic, mostly triggered by fatigue, emotional excitement, and exposure to cold, etc. It is recommended that patients who have similar symptoms need to have a complete diagnosis of the symptoms. It is recommended that patients with similar symptoms need to improve the electrocardiogram, dynamic electrocardiogram or even cardiac ultrasound and other tests to determine whether there is ischemia or arrhythmia.
