title: Tombstone-like electrocardiographic changes during exercise stress test.
abstract: A 45-year-old man showed tombstone-like electrocardiographic change during stage 1 of stress testing, using Bruce protocol. The raw rhythm strip did not show any ST-T changes. These pseudochanges were probably the result of computer-synthesized averaging algorithm errors.
