What could be causing a sensation of bees in the chest, potentially accompanied by shortness of breath, chest pain, or palpitations, in an adult or adolescent with a possible history of anxiety, panic disorders, or cardiac conditions?

Sensation of "Bees in Chest"

A sensation of "bees" or buzzing in the chest most commonly represents anxiety-related chest symptoms, musculoskeletal pain, or gastroesophageal reflux disease, but cardiac causes must be excluded first through appropriate evaluation including ECG and cardiac biomarkers before attributing symptoms to non-cardiac etiologies. 1

Immediate Evaluation Required

Cardiac evaluation must always come first when evaluating chest sensations, regardless of how the patient describes them. 2

• Obtain a 12-lead ECG within 10 minutes of presentation to exclude acute coronary syndrome, ST-elevation myocardial infarction, or arrhythmias 1
• Measure cardiac troponin as soon as possible if any cardiac concern exists 1
• Assess vital signs including heart rate, blood pressure, respiratory rate, and oxygen saturation 2
• Perform focused cardiovascular examination to identify life-threatening causes such as aortic dissection, pulmonary embolism, or pericarditis 1

Critical red flags requiring emergency evaluation include: exertional symptoms, radiation to arm/jaw/neck, associated diaphoresis, dyspnea, nausea, palpitations, or syncope. 2, 3

Most Likely Non-Cardiac Causes

Anxiety and Panic Disorders

After negative cardiac workup, anxiety is the most common cause of unusual chest sensations including buzzing, vibrating, or "bee-like" feelings. 1, 2

• Anxiety triggers sympathetic nervous system activation causing increased heart rate, blood pressure elevation, and muscle tension in the chest wall, creating sensations of tightness, pressure, or unusual vibrating feelings 2
• Central nervous system-visceral interactions, heightened body vigilance, and lowered pain thresholds contribute to these atypical sensations 1, 2
• Hyperventilation associated with anxiety can cause chest muscle spasms, contributing to buzzing or vibrating sensations 2
• Symptoms often worsen with stress and may be accompanied by shortness of breath, palpitations, and sweating 2, 4

Musculoskeletal Causes

• Costochondritis presents with chest wall tenderness reproducible on palpation and accounts for the majority of non-cardiac chest pain cases 4, 3
• Muscle tension or spasm in intercostal muscles can create unusual sensations including vibrating or buzzing feelings 4
• Pain is typically sharp, localized, and affected by breathing, turning, or chest wall movement 3

Gastroesophageal Causes

• GERD is the most common esophageal cause of non-cardiac chest pain, often presenting as pressure, burning, or unusual sensations 1, 4
• Symptoms typically occur after meals or at night and may improve with antacids 1, 3
• Esophageal spasm can produce squeezing sensations that patients may describe as vibrating or buzzing 1

Diagnostic Algorithm

Step 1: Rule out cardiac causes

• ECG, cardiac biomarkers, and focused cardiovascular examination 1, 2
• Consider stress testing or echocardiography for intermediate-risk patients 2

Step 2: Evaluate for pulmonary causes if respiratory symptoms present

• Chest radiography to exclude pneumothorax, pneumonia, or mediastinal abnormalities 1, 4
• Consider pulmonary embolism if tachycardia and dyspnea present in >90% of cases 4

Step 3: Assess for gastrointestinal causes

• Trial of empiric acid suppression therapy for suspected GERD 1
• Consider upper endoscopy if symptoms persist or alarm features present (dysphagia, weight loss, bleeding) 1

Step 4: Evaluate for anxiety/psychological factors

• Screen for anxiety disorders, panic attacks, depression, and cardiophobia 1, 2
• Assess for somatoform disorders if recurrent presentations with negative workups 1

Management Approach

For Confirmed Anxiety-Related Symptoms

Referral to cognitive-behavioral therapy is reasonable for patients with recurrent similar presentations and negative cardiac workups (Class 2a recommendation). 1, 2

• Cognitive-behavioral therapy has demonstrated a 32% reduction in chest pain frequency in patients with non-cardiac chest pain 1, 2, 4
• Acute management includes sensory grounding techniques, breathing exercises, and progressive muscle relaxation 2
• Provide reassurance about negative cardiac findings while validating the patient's symptoms 2

For Musculoskeletal Pain

• NSAIDs if indicated for costochondritis 3
• Physical therapy and stretching exercises 4

For GERD

• Empiric trial of proton pump inhibitors 1
• Lifestyle modifications including avoiding late meals and trigger foods 1

Critical Pitfalls to Avoid

Never attribute chest symptoms to anxiety before completing appropriate cardiac evaluation. 2, 4

• Premature attribution to anxiety leads to missed diagnoses of serious conditions, especially in younger patients 2, 4
• Patients with known anxiety disorders still require appropriate cardiac evaluation when presenting with new or changed chest symptoms 2
• Women may describe chest pain differently than men, using terms like "tearing" and experiencing pain more often in back, neck, and jaw 2, 4
• Patients with anxiety-related chest pain often undergo extensive repetitive cardiac testing with low referral rates to mental health services, representing a lost opportunity for effective treatment 1

Physical examination findings that reduce probability of cardiac cause: chest tenderness on palpation, pain with inspiration, and reproducible pain with chest wall pressure. 1, 3

Descriptors suggesting lower probability of ischemia: stabbing, sharp, fleeting, pleuritic, or shifting pain. 1
