Feeling empty and uncomfortable in the heart is a sign of heart qi deficiency and heart blood deficiency according to Chinese medicine. Western medicine considers the possibility of cardiac arrhythmia, especially mostly seen in bradycardia. ECG examination should be improved to clarify the type of arrhythmia and whether there is insufficient blood supply to the heart muscle. If the test results, suggest bradycardia with a heart rate above 50 beats/min, you can temporarily observe, and if necessary, take oral aminophylline tablets to elevate the heart rate. If the heart rate is consistently below 50 beats/min and symptoms of dizziness, syncope, and transient blackouts occur, a pacemaker needs to be installed for treatment.
