Most of the sudden heart thumps are arrhythmias, when the arrhythmia is atrial premature beats or ventricular premature beats. There are many reasons for this, depending on whether it is physiological or organic heart disease, for example, physiological reasons are no organic heart disease, suddenly a large amount of alcohol, coffee, tea, or emotional excitement, long late nights, poor rest, suddenly appear heart thump. This is the time to identify whether the stuttering is frequent or occasional, if occasional can not be managed, observation can be. If it is more frequent, you need to see a hospital for an electrocardiogram or 24-hour ambulatory electrocardiogram to find out what type of arrhythmia is present and its cause. In patients with organic heart disease, a sudden heart thump may be induced by atrial premature beats in patients with hypertension, which may again induce atrial tachycardia and atrial fibrillation, or in patients with coronary artery disease, which may induce ventricular tachycardia or ventricular tachycardia and ventricular fibrillation due to frequent ventricular premature beats, which can seriously endanger life, such as valvular heart disease and dilated cardiomyopathy, and a thump should be taken seriously. Otherwise, it will endanger the patient’s health.
