The beat to beat variation of heart rate, Valsalva test and the difference in blood pressure taken in supine and upright position were studied in 3 groups of individuals, namely, group A——100 normal persons as control; group B——45 cases of diabetes without autonomic neuropathy, and group C——70 cases of diabetes with autonomic neuropathy. In group A, B and C, (1) the difference in heart rate between deep inspiration and expiration was 19.5±1.3, 18.7±1.3 and 11.1±1.2 beats per minute; (2) the response...

The beat to beat variation of heart rate, Valsalva test and the difference in blood pressure taken in supine and upright position were studied in 3 groups of individuals, namely, group A——100 normal persons as control; group B——45 cases of diabetes without autonomic neuropathy, and group C——70 cases of diabetes with autonomic neuropathy. In group A, B and C, (1) the difference in heart rate between deep inspiration and expiration was 19.5±1.3, 18.7±1.3 and 11.1±1.2 beats per minute; (2) the response index to Valsalva maneuver was 1.215±0.020, 1.237±0.037 and 1.109±0.022; (3) the difference of heart rate in upright and supine position was 17.9±1.7, 21.6±2.4 and 13.1±1.7 beats per minute; (4) the ratio of 30th to 15th R-R intervals was 1.105±0.15, 1.063±0.021 and 1.001±0.011 and (5) the average difference in blood pressure taken in supine and upright position was 2.76, 7.87 and 11.57 mmHg respectively. 11 eases (15.7%) in group C showed orthostatic hypotension. There were significant difference (p<0.001) between group A or B and group C in beat to beat variation of heart rate. All the above methods are non-invasive and easily accepted by patients, while these methods may be quite helpful in early diagnosis of diabetic cardiovascular autonomic neuropathy.
