Exercise testing and portable ECG recording in arrhythmia-prone patients.

To detect transient arrhythmias or conduction disturbances, 200 patients with the symptoms of palpitations, syncope or dizziness, and patients with coronary heart disease, angina pectoris, arrhythmias or conduction disturbances on resting 12-lead electrocardiogram, were studied by submaximal treadmill exercise and portable Holter recording. Thirty-nine patients (19.5%) had arrhythmias on the resting 12-lead ECG, 136 patients (68%) showed arrhythmias either on treadmill or Holter recording or both. Eighty-nine patients (44.5%) showed arrhythmias on exercise, while 123 patients (61.5%) had rhythm or conduction disturbances on Holter recording. Twenty-two patients (11%) had arrhythmias only on treadmill walking, while 68 (34%) had arrhythmias only with the Holter. In six patients different arrhythmias was noted by each method. Although the Holter recording technique affords a higher yield of recording transient arrhythmias than did exercise testing, both methods are useful and complementary in evaluating the ambulatory patients suspected of having rhythm or conduction disturbances.

Neonatal polycythemia.

461 consecutive inborn babies, delivered during the period September 1993-March 1994 were subjected to a microhematocrit assessment at 6 hours of age to determine the incidence of polycythemia. 47 babies (inborn and out born), admitted to the neonatal unit with confirmed polycythemia were studied for clinical and laboratory abnormalities. These 47 babies were then randomly assigned to receive partial exchange transfusion with either normal saline or fresh plasma. The incidence of polycythemia was 27 of 461 (5.8%). 23 of 27 (85.1%) were term babies and 15 of 27 (55.5%) were small for gestational age. 14 of 27 (51.1%) babies had mothers who had pregnancy induced hypertension. Feeding problems (16/47) and lethargy (25/47) were the commonest symptoms (34% and 51% respectively). 25 of 47 (51%) babies had hypoglycemia and 5 of 47 (10.6%) had hypocalcemia. Thrombocytopenia was seen in 13/47 (27.65%) of cases. 24 babies received normal saline and 23 received fresh plasma for partial exchange transfusion. The immediate post-exchange fall in hematocrit was significant in both groups and this was well sustained over the following 48 hours. However, improvement in clinical and laboratory parameters was more remarkable with fresh plasma. Polycythemia appears to be a real clinical entity in neonates in India and babies with known risk factors should be actively screened for this condition. Once diagnosis is established special attempts should be made to rule out hypoglycemia. For treatment of polycythemia fresh plasma is preferable for partial exchange transfusion but normal saline appears to be an adequate substitute.
