- Exemplo 1 | Example #1

Paciente do sexo masculino, 33 anos, com relato de dor torácica. Ao ECG, apresenta ritmo sinusal regular com frequência cardíaca de 66 bpm. Percebe-se onda T positiva, simétrica e pontiaguda nas derivações V3, V4, V5 e V6. Indica **isquemia subendocárdica** e possível síndrome coronariana aguda.

*A 33-year-old male patient presenting with chest pain. The ECG reveals a regular sinus rhythm with a heart rate of 66 beats per minute. In leads V3, V4, V5, and V6, there are positive, symmetrical, and pointed T waves. This pattern suggests **subendocardial ischemia**, which may indicate the possibility of acute coronary syndrome.*

Paciente do sexo feminino, 64 anos, com relato de dor torácica. Ao ECG, apresenta ritmo sinusal regular com frequência cardíaca de 80 bpm. Percebe-se onda T positiva, simétrica e pontiaguda nas derivações DII, DIII, aVF, V3, V4, V5 e V6. Indica isquemia subendocárdica e possível síndrome coronariana aguda.

*A 64-year-old female patient presenting with chest pain. The ECG shows a regular sinus rhythm with a heart rate of 80 beats per minute. Notably, there is a positive, symmetrical, and pointed T wave present in leads II, III, aVF, V3, V4, V5, and V6. This finding suggests **subendocardial ischemia** and indicates the possibility of acute coronary syndrome.*
