Occasional heart beats are considered premature beats, which may be atrial, ventricular or junctional. If the beats are frequent, it is important to improve the electrocardiogram to clarify the type and frequency of the beats and the presence of atrial and ventricular tachycardia. Occasional heart beats are seen in many young patients, mainly associated with chronic mental stress, smoking, and staying up late, which can lead to functional premature beats due to cardiac neurological disorders. In older patients or those with underlying heart disease, the heart beats more frequently and the main focus is on treating the cause.
