From the Guidelines
The best course of action for an anorexia patient with a heart rate of 33 bpm who is refusing help in the community is immediate emergency medical intervention. This patient requires urgent hospitalization, likely via emergency services, as a heart rate this low represents a medical emergency with risk of sudden cardiac death. Medical professionals should initiate cardiac monitoring, careful fluid resuscitation, and electrolyte correction under close supervision, as recommended by the American Heart Association 1. The patient may require involuntary admission under mental health legislation due to the life-threatening nature of their condition, as they lack capacity to make safe decisions about their care.
Once medically stabilized, a multidisciplinary approach including psychiatric evaluation, nutritional rehabilitation with careful refeeding to avoid refeeding syndrome, and psychological support will be needed, as outlined in the American Psychiatric Association practice guideline for the treatment of patients with eating disorders 1. The extreme bradycardia (slow heart rate) is likely due to the body's adaptation to starvation, with decreased metabolic rate and cardiac muscle atrophy, which can lead to dangerous arrhythmias and cardiac arrest without immediate intervention.
Some key considerations in the management of this patient include:
- Cardiac monitoring and careful fluid resuscitation to manage the risk of sudden cardiac death 1
- Electrolyte correction to prevent arrhythmias and other complications 1
- Involuntary admission under mental health legislation if necessary, to ensure the patient's safety and well-being 1
- A multidisciplinary approach to care, including psychiatric evaluation, nutritional rehabilitation, and psychological support, to address the underlying eating disorder and related comorbidities 1
- Consideration of technology-based psychological interventions, such as guided CBIs, as an adjunct to traditional therapy or for patients who are unable or unwilling to access in-person treatment 1.
This situation represents both a psychiatric and medical emergency requiring prompt action regardless of the patient's willingness to accept help.

From the Research
Key Considerations for the Patient
- The patient's heart rate of 33bpm is a significant concern, as it indicates severe sinus bradycardia, a common cardiovascular complication in anorexia nervosa 2, 3.
- The patient's refusal to accept help from eating disorder services is a challenge, as early psychiatric intervention and multidisciplinary management are crucial to address malnutrition, electrolyte imbalances, and cardiac dysfunction 2.
- The patient's condition may be associated with a high risk of sudden death, especially in the presence of other arrhythmias or EKG abnormalities, such as prolongation of the QTc interval 3.
Potential Course of Action
- Referral to a tertiary care center for treatment by eating disorder specialists is recommended, as they can provide multidisciplinary management and address the patient's cardiac and psychiatric needs 3.
- Long-term cardiac monitoring may be necessary to detect potential arrhythmias and prevent sudden death 4.
- Weight restoration and nutritional support are essential to improve the patient's cardiac function and overall health 4.
- The patient's electrolyte levels, including magnesium, should be monitored and managed to prevent further complications 2.
Community-Based Support
- It is essential to engage with the patient's community and family to encourage them to support the patient in seeking help from eating disorder services 2.
- Education and awareness about the risks and complications of anorexia nervosa, particularly regarding cardiac health, may help the community understand the importance of seeking professional help 5.
