The Nurse at the Monitor: How the Coronary Care Unit Moved Defibrillation Into Nursing in the 1960s

The Change

In the early 1960s, a new kind of hospital unit appeared in the United States and Britain: the coronary care unit, a small ward where patients recovering from acute myocardial infarction were placed together, connected to continuous electrocardiogram monitors and watched around the clock by nurses trained to recognize dangerous heart rhythms. The change this paper follows is one element of that unit that turned out to be larger than the unit itself: the decision that nurses, not only physicians, would interpret the monitor and, when a physician was not present, deliver an electric shock to a patient in ventricular fibrillation. That decision moved a life-saving medical intervention into nursing practice within a few years, and it became a model for how intensive care nursing would develop (Fairman & Lynaugh, 1998).

What Forced It

Three pressures converged. The first was new evidence about when patients with heart attacks died. Physicians had come to recognize that many deaths in the first days after myocardial infarction were caused not by failure of the heart muscle but by sudden arrhythmias, especially ventricular fibrillation, which could be reversed if treated within minutes. In a paper in The Lancet in 1961, the British cardiologist Desmond Julian argued that patients with acute myocardial infarction should be cared for in special units with continuous monitoring and staff trained to act immediately on cardiac arrest (Julian, 1961).

The second pressure was technology. External defibrillation had been demonstrated in the 1950s, closed-chest cardiac massage was described in 1960, and electrocardiogram monitors that could display a patient's rhythm continuously at the bedside became practical at about the same time. For the first time, a fatal rhythm could be seen as it began and reversed on the spot. The third pressure was time and staffing. Ventricular fibrillation left minutes to act, and hospitals could not keep a physician beside every monitored patient day and night. The people who were always there were nurses. If the new technology was to save lives, someone who was present had to be allowed to use it.

A Short Chronology

1956 to 1960: External defibrillation of the heart through the closed chest is demonstrated, and in 1960 a team at Johns Hopkins describes closed-chest cardiac massage, showing that circulation can be maintained without opening the chest (Kouwenhoven et al., 1960). Resuscitation no longer requires a surgeon.

1961: Julian proposes units for patients with acute myocardial infarction staffed to respond immediately to cardiac arrest (Julian, 1961).

1962 to 1963: The first coronary care units open in the United States, in Kansas City, Philadelphia and elsewhere, with nurses trained to watch continuous monitors.

Mid-1960s: Standing orders authorizing nurses to defibrillate spread with the units; nurses receive formal instruction in arrhythmia recognition.

Late 1960s to early 1970s: Critical care nursing organizes as a specialty with its own professional association and, later, certification.

The chronology shows how quickly the change moved. Fewer than ten years separated the first description of closed-chest massage from routine nurse-delivered defibrillation in coronary care units, a pace that left law and education behind practice.

Who Objected, and Why

The change was contested. Some physicians and hospital administrators objected that diagnosing an arrhythmia and deciding to shock a patient were medical acts that nurses had neither the training nor the legal authority to perform. Nurse practice laws of the period did not clearly permit nurses to make such decisions, and hospitals worried about liability if a nurse shocked a patient in error. Some nurses shared the hesitation, fearing responsibility for decisions that had always belonged to physicians and uncertain whether their education had prepared them. The objection was reasonable on its own terms: the move did hand nurses a decision with life-or-death consequences, and it was made before law and education had caught up.

The early coronary care units answered the objection through training and standing orders rather than through changes in law. Nurses in these units received intensive instruction in rhythm recognition and resuscitation, often from the physicians who ran the units, and physicians wrote standing orders authorizing nurses to defibrillate when a specific rhythm appeared and no physician was present. Fairman and Lynaugh (1998) describe how this arrangement gave nurses a new clinical authority while keeping it formally under physician direction, a compromise that let the practice spread faster than the law changed.

What the Change Became

Within a decade, the coronary care unit had spread widely, and the nurse's role in it had grown from watching a monitor to managing a patient's rhythm, titrating drugs under protocols and responding to emergencies before a physician arrived. The model extended to other intensive care units, and critical care nursing developed as a specialty with its own professional organization, certification and body of knowledge. The standing order, which had been a workaround, became a routine instrument through which nurses exercise defined clinical judgment in many settings today. Fairman and Lynaugh (1998) argue that intensive care units became places where nurses' expertise was most visible and where the boundary between nursing and medicine was renegotiated in practice, often ahead of formal changes in role.

What It Shows About How Nursing Changes

The case suggests that nursing's scope has often expanded not because nurses asked for it but because a new technology required someone to be present and able to act, and nurses were the ones present. The authority arrived first as a practical necessity, was formalized through standing orders and training, and only later appeared in law and professional standards. A nurse who today interprets a telemetry strip and follows a protocol for a new arrhythmia is working within an arrangement negotiated in the coronary care units of the 1960s. The history also carries a caution: when authority is extended because of staffing and technology rather than education, the education has to be built afterward, and the early units succeeded largely because they invested in training their nurses before asking them to act.

The same pattern is visible now in newer technologies, such as early warning scores and remote monitoring, where nurses are again the people present when the data arrive and again depend on protocols to act. Whether the education keeps pace this time is a question the coronary care units answered well and that each new technology asks again.
