tombstoning
Extreme ST-segment elevation resembling a tombstone shape, indicating massive myocardial infarction.
Full Definition
Tombstoning is an electrocardiographic pattern characterized by extreme ST-segment elevation that merges with tall, upright T waves, creating a monophasic morphology resembling the shape of a tombstone. This pattern typically indicates massive transmural myocardial infarction with complete coronary occlusion and extensive myocardial damage. Tombstoning is most commonly seen in acute anterior STEMI due to proximal left anterior descending artery occlusion and carries a poor prognosis with high mortality risk. The term reflects both the ECG appearance and the grave clinical implications.
Usage
Usage note: Informal but widely recognized term; indicates need for urgent intervention.
