A 60-year-old male patient is admitted with chest pain to the telemetry unit where you work. While having a bowel movement on the bedside commode, the patient becomes short of breath and diaphoretic. The ECG waveform shows bradycardia.
What other assessment findings should you anticipate?
Why does this patient probably have bradycardia?
Does this dysrhythmia need treatment? Why or why not? What intervention would you implement first?
What is the drug treatment and dosage of choice for symptomatic bradycardia? How does this drug increase heart rate?
Other assessment findings that you might anticipate in a 60-year-old male patient
Other assessment findings that you might anticipate in a 60-year-old male patient admitted with chest pain who becomes short of breath and diaphoretic while having a bowel movement on the bedside commode, with an ECG waveform showing bradycardia, include:
Vital signs:
Blood pressure: May be low, normal, or high, depending on the underlying cause of the bradycardia and chest pain.
Respiratory rate: May be increased, decreased, or normal, depending on the severity of the bradycardia and respiratory distress.
Temperature: May be normal or elevated, depending on the presence of infection or other underlying medical conditions.
Physical exam:
Skin: May be pale, cool, and clammy due to poor blood perfusion.
Heart: Heart rate may be slow and regular (bradycardia), or it may be irregular (arrhythmia). Heart sounds may be weak or muffled.
Lungs: Lung sounds may be crackles (rales) or wheezes, indicating fluid or inflammation in the lungs.
Abdomen: May be distended and tender, indicating bowel obstruction or other abdominal pathology.
The patient's bradycardia is likely due to a vagal response. The vagus nerve is one of the main parasympathetic nerves in the body. It helps to regulate heart rate, blood pressure, and digestion. When the vagus nerve is stimulated, it can cause a decrease in heart rate and blood pressure.
In this case, the patient's vagus nerve may have been stimulated by the following factors:
Bowel movement: Having a bowel movement can sometimes stimulate the vagus nerve, especially in patients with underlying heart disease.
Pain: Chest pain can also stimulate the vagus nerve.
Anxiety: The patient's anxiety about his symptoms may also contribute to the vagal response.
It is also important to consider other possible causes of the patient's bradycardia, such as:
Medications: Certain medications, such as beta-blockers and digoxin, can cause bradycardia.
Heart disease: Bradycardia can be a sign of underlying heart disease, such as coronary artery disease, heart failure, or arrhythmia.
Other medical conditions: Bradycardia can also be caused by other medical conditions, such as hypothyroidism, hypoglycemia, and electrolyte imbalances.
To further evaluate the patient's condition, the healthcare team would likely order additional tests, such as blood tests, chest X-ray, and echocardiogram. Treatment would be directed at the underlying cause of the bradycardia and any other medical conditions that may be present.
