On attack

1. ST elevations in V2-6, II, III, and aVF were observed

1. ST elevations in V2-6 were observed

2. Negative T in V1-6 were observed

2 days later

1. ST elevations in V2-6 were decreased, and negative T in V1-6 were observed

1. ST elevations in V2-6 were decreased

2. Negative T in V3-6, I, II, and aVL were observed

Male: 2 months later

Female: 1 month later

1. Negative T in V1-6, II, III, and aVF were observed
