The beta-blocking action of 100 mg per diem Atenol was evaluated in 8 patients with conditions requiring treatment with a beta-blocking drugs (ischaemic cardiopathy, arterial hypertension, hypertrophic myocardiopathy). Ergometer bicycle exertion tests were used to evaluate the extent of Atenol's beta-blocking action (in basal condition, 3 and 24 hours after administration of the drug) as well as Holter type dynamic ECG recordings (basal and under treatment). The drug significantly reduced cardiac frequency and arterial pressure both at rest and under exertion. It also significantly reduced average hourly and daily cardiac frequency as shown by dynamic ECG. No side effects of the drug were observed.

Atenolol, a cardio selective beta-adrenergic blocker, frequently prescribed in various cardiac ailments, has not been thoroughly investigated for its adverse reaction profile in Indian patient. The present ADR monitoring study which was open, prospective and collaborative was therefore planned. A total of 440 patients with various heart disease were enrolled after a strict inclusion and exclusion criteria from Maulana Azad Medical College, New Delhi and J.N. Medical College, Aligarh. fifteen patients dropped out leaving 435 for final analysis. Cold extremities occurred in 1.18% headache and dizziness in 1.41% breathlessness in 0.94% oedema in 0.70% and bradycardia in 0.47%. Adverse drug reaction in our study were less than those reported from Western countries. Better patient selection, optimal dose could have reduced the frequency of ADR in the present study. Racial factor and season might be operating to bring down ADR to atenolol in Indian patients.

To confirm the usefulness of head-up tilt test (HUT) in neurocardiogenic syncope (NCS) with complicating clinical features, retrospective analysis were done on 12 selected children. The age at onset was 12.7 +/- 1.9 (mean +/- SD) years. Associated clinical features were postoperative congenital heart disease (PO CHD) in 3, coexistent arrhythmia in 8 (persistent ventricular arrhythmia during exercise in 3, premature ventricular contractions in 2, ventricular couplets in 1, sinoatrial exit block in 1 and resting sinus bradycardia in 1) and ST segment depression during exercise in 1. Four of them had a history of exercise-related syncope. All 3 patients with PO CHD had arrhythmia (ventricular tachycardia in 1, sinus bradycardia in 1 and atrioventricular block in 1). HUT provoked NCS in 8 (2 during baseline tilt, 6 during isoproterenol infusion). In one each, ventricular tachycardia and loss of consciousness without hypotension and bradycardia were induced. Atenolol was tried in 5 with improvement of NCS in 4 and aggravation of dizziness in 1. During follow-up, 7 became asymptomatic (2 with atenolol) and 5 were stationary. In conclusion, HUT was valuable in diagnosing NCS even in children with complicating clinical features such as arrhythmias or PO CHD. HUT could be done as apart of initial diagnostic tests if the past history suggests NCS, regardless of associated clinical features. In some cases, the unexpected results of the test turned out useful in managing children with syncope or dizziness.
