Transesophageal atrial pacing (TAP) 2D echocardiography was performed after placebo (P) and gallopamil (G) (0.03 mg/kg iv) in 12 patients with stable, reproducible, effort angina. If compared to P study, during G the following changes were observed: 3 out of the 12 patients did not experience angina, time to ST-1mm increased from 5.3 +/- 1.3 to 6.6 +/- 1.6 min (p less than 0.05), wall motion score was improved both at 130 b/min (15.3 +/- 4.1 drug P, 17 +/- 4.8 drug G, p less than 0.01) and at 150 b/min (10.9 +/- 5.7 drug P, 12.8 +/- 6.3 drug G, p = 0.07). In conclusion, gallopamil has a beneficial effect on atrial pacing induced ischemia: it increases pacing time to ischemic threshold and reduces during ischemia the extent of dysfunctional myocardium.
