Subtyping cardiac arrest with ECG waveforms

A patient is rushed into the ER, unconscious and in cardiac arrest. As the physician begins the resuscitation, she knows only that the patient’s heart has stopped—but nothing else. What happened to cause the arrest? What immediate actions need to be taken? And what will happen to the patient? One of the only pieces of data available to the emergency physician in this situation is the electrocardiogram (ECG), which measures the electrical activity of the heart. Physicians use this to determine which immediate actions are needed: most importantly, does the patient need to be shocked (cardioverted), or need some critical medication to restart the heart. This rich signal might also contain other clues: about why the heart stopped, what physicians can do in the ER to give the patient the best possible chance of surviving, and the likelihood that a patient who survives will have a normal life, without profound physical or neurological impairments.一名患者被紧急送入急诊室（Emergency Room, ER），陷入昏迷且发生心脏骤停。当医师着手开展复苏操作时，她仅知晓患者心脏已停止跳动，其余信息一概无从得知。究竟是何种诱因引发了此次心脏骤停？需要立即采取哪些救治措施？患者的病情后续将如何发展？在此场景中，急诊医师可获取的为数不多的关键数据之一便是心电图（electrocardiogram, ECG），该设备可检测心脏的电活动。医师借助这一检测结果来判断所需采取的紧急救治手段：最为核心的是，患者是否需要接受电击复律（cardioverted），或是需要使用关键药物来恢复心脏搏动。这一丰富的电生理信号或许还暗藏其他诸多线索：涵盖心脏骤停的诱因、急诊医师可采取哪些措施以最大程度提升患者的生存概率，以及存活患者日后能否拥有正常生活、不会出现严重躯体或神经功能缺损的可能性。
