      A patient in whom exercise induced reversible ischaemic left anterior fascicular block is reported. Glyceryl trinitrate relieved the fascicular block. Coronary angiography showed a 90% obstruction of the left anterior descending artery. The left anterior fascicular block induced by exercise disappeared after a successful coronary angioplasty.
