If the pulse in the hand is beating distinctly with a strong beat, this indicates that it may be a symptom of tachycardia. Once this symptom is present, it is likely to be due to a physiological cause, such as anemia, malnutrition, or excitement or stress after exercise, which often occurs and requires an immediate ECG. If tachycardia is determined by the EKG, rest in place and medication to control the heart rate, such as bethanechol, metoprolol, etc., is required. By taking the medication, the heart rate can be relieved quickly, and the patient will gradually become less uncomfortable, but it is necessary to go to the hospital for active treatment, and to achieve the goal of human health through examination and treatment.
