Hello, As per your question I understand that there are two problems - low sugars and slow heart rate of 44/min. It depends on what medications you are taking. Some of the BP medications can slow your heart rate. Again your diabetic medications, your diet pattern also needs reviewing to see why your sugars are going low? So I will need list of your medications to come to a conclusion. You cannot do much to improve the heart rate, it can be treated by medications if you are having symptoms because of slow heart rate.
