Here is a thorough, textbook-sourced answer on chest tightness:

Chest Tightness - Causes and Clinical Significance

Chest tightness is a symptom (not a single "sign"), and it is associated with a wide range of conditions spanning multiple organ systems. Here is a structured breakdown:

1. Cardiac Causes

Condition	Character of Discomfort	Key Features
Angina / Myocardial Ischemia	Pressure, tightness, squeezing, burning	Retrosternal; radiates to jaw, neck, shoulders, or arms; triggered by exertion or cold
Myocardial Infarction (MI)	Same as above but lasting >30 min	At rest; associated with diaphoresis, nausea, dyspnea
Pericarditis	Sharp, pleuritic	Relieved by leaning forward; pericardial friction rub

Harrison's Principles of Internal Medicine 22E, Table of Cardiovascular Causes

2. Pulmonary Causes

Chest tightness arising from the lungs is due to stimulation of pulmonary receptors (mechanoreceptors in the airways and lung parenchyma):

Asthma - the classic cause of chest tightness; episodes of bronchoconstriction cause tightness, wheezing, dyspnea, and cough. In younger patients, chest tightness is particularly associated with asthma more than other cardiac or pulmonary disorders.
Pulmonary edema with bronchospasm - fluid in alveoli triggers airway constriction
Toxic inhalations with bronchospasm - e.g., occupational exposures
Byssinosis - cotton/organic dust exposure; classic "Monday chest tightness" (tightness on the first workday of the week)
Pulmonary Embolism (PE) - sudden onset; pleuritic pain, dyspnea, tachycardia
Pulmonary Hypertension - substernal tightness, exertional, with signs of raised venous pressure
Pneumonia/Pleuritis - unilateral pressure with fever, cough, decreased breath sounds
Pneumothorax - sudden lateral chest tightness/pain
Murray & Nadel's Textbook of Respiratory Medicine, Table 36.1
Fishman's Pulmonary Diseases and Disorders

3. Gastrointestinal Causes

Condition	Character	Key Feature
GERD (Acid Reflux)	Burning	Retrosternal; worse postprandially; relieved by antacids
Esophageal Spasm	Pressure, tightness, intense squeezing	Can closely mimic angina
Peptic Ulcer	Burning	Epigastric; 60-90 min after meals
Gallbladder disease	Colicky	Right-sided

4. Anxiety / Psychiatric Causes

Panic attacks and generalized anxiety disorder can cause intense chest tightness, breathlessness, and dizziness, sometimes spiraling into symptoms mistaken for an asthma or cardiac event.
High comorbidity exists between asthma and anxiety/depressive disorders.
Kaplan & Sadock's Comprehensive Textbook of Psychiatry

5. Anaphylaxis

Chest tightness is part of the systemic anaphylactic response, along with pruritus, wheezing, hypotension, and urticaria.
Goldman-Cecil Medicine

6. Exercise-Induced Bronchospasm (EIB)

Chest tightness + wheezing + cough after exercise; confirmed by a 10-15% drop in FEV1 post-exercise.
Textbook of Family Medicine 9e

Key Clinical Principle

"No single symptom is specific, but chest tightness in a younger patient is more often associated with asthma than with cardiac or other pulmonary disorders."

Fishman's Pulmonary Diseases and Disorders

When a patient presents with chest tightness, the most important immediate concern is to rule out life-threatening causes first: acute coronary syndrome (ACS), aortic dissection, pulmonary embolism, and tension pneumothorax.

Quick Diagnostic Approach

Clue	Likely Cause
Exertional, radiates to arm/jaw	Angina / MI
With wheezing, atopy, worse at night	Asthma
After meals, burning	GERD / Esophageal cause
Sudden, after long travel, with hypoxia	Pulmonary Embolism
With panic, anxiety, dizziness	Anxiety/Panic disorder
First day back at work, occupational	Byssinosis
With hives, hypotension	Anaphylaxis

⚠️ Please Read This First

What you're describing - extreme stress, irregular heartbeat, and difficulty breathing - is something that needs proper medical evaluation. An ECG (electrocardiogram) and basic blood tests can quickly clarify what's happening. Please see a doctor soon, especially if symptoms are frequent or severe.

What's Likely Happening to You

The Stress-Heart-Breathing Connection

When you're under extreme stress, your body activates the sympathetic ("fight-or-flight") nervous system, releasing adrenaline (norepinephrine and epinephrine). This directly affects your heart and breathing. Here's the full chain:

Extreme Stress
      ↓
Sympathetic nervous system activation + Adrenaline release
      ↓
Heart rate increases → Atrial electrical activity becomes disorganized
      ↓
Irregular heartbeat (palpitations / arrhythmia)
      ↓
Reduced efficiency of heart pumping → Less oxygen delivery
      ↓
Breathing becomes faster/labored to compensate → Dyspnea

The Irregular Heartbeat You're Feeling

You mention feeling irregularity specifically in the right atrium area. The right atrium is where the heart's natural pacemaker (the SA node) sits. Stress can disrupt this pacemaker directly. Several arrhythmia types can arise from the atria under stress:

Type	What it is	Triggered by stress?
Sinus Tachycardia	Fast but regular beats from the SA node	Yes - most common stress response
PACs (Premature Atrial Contractions)	Extra beats from the atria - feel like "skipped" or "extra" beats	Yes - very common, usually benign
SVT (Supraventricular Tachycardia)	Sudden rapid heart rate from atrial circuits	Yes - stress is a known trigger
Atrial Fibrillation (AFib)	Chaotic, irregular atrial activity - most common sustained arrhythmia	Yes - stress can trigger/worsen it

Harrison's Principles of Internal Medicine 22E - Supraventricular Arrhythmias, Table 23-1

Could This Be a Panic Attack?

Your combination of symptoms very closely matches panic disorder / panic attacks, which are extremely common with extreme stress:

Diagnostic criteria for a panic attack include (4 or more of these):

Palpitations, pounding heart, or accelerated/irregular heart rate ✓ (you have this)
Shortness of breath ✓ (you have this)
Sweating
Trembling or shaking
Chest pain or tightness
Dizziness or lightheadedness
Fear of dying or losing control
Numbness or tingling sensations

Harrison's Principles of Internal Medicine 22E - Panic Disorder
Kaplan & Sadock's Comprehensive Textbook of Psychiatry

Key fact from Harrison's: Panic disorder was the primary diagnosis in 43% of patients with chest pain who had normal coronary angiograms, and was present in 9% of all patients referred for cardiac evaluation. This is extremely common.

Why Breathing Is Affected

Your irregular heartbeat reduces the heart's pumping efficiency. When each beat is irregular, less blood (and therefore less oxygen) reaches the body per minute. Your brain detects low oxygen and signals faster, heavier breathing to compensate - this is the dyspnea you feel.

Additionally, anxiety itself directly stimulates breathing centers, causing hyperventilation - breathing too fast and too shallowly - which paradoxically makes you feel even more short of breath and can worsen palpitations.

Important: When to Go to Emergency Care Immediately

Go to the ER right now if you experience any of these:

Chest pain spreading to your arm, jaw, or back
Fainting or near-fainting
Heart rate persistently above 150 beats/min
Severe shortness of breath at rest that doesn't improve
Blue/purple lips or fingertips
Sudden severe headache

What You Can Do Right Now (While Awaiting Medical Evaluation)

For immediate relief during an episode:

4-7-8 breathing - Inhale for 4 sec, hold for 7 sec, exhale slowly for 8 sec. This activates the vagus nerve and slows heart rate.
Cold water on face - Triggers the diving reflex, which slows heart rate rapidly.
Sit or lie down - Reduces cardiac workload.
Avoid caffeine, energy drinks, and stimulants - These worsen atrial irritability.

Longer term:

See a doctor for an ECG (electrocardiogram) and possibly a 24-hour Holter monitor to capture the irregular rhythm.
Bloodwork to rule out thyroid disease (hyperthyroidism causes palpitations + anxiety + breathlessness) and anemia.
Stress management: cognitive behavioral therapy (CBT), regular exercise, and adequate sleep are evidence-based.

Bottom line: What you're experiencing is very likely stress-driven atrial irritability (most commonly PACs or sinus arrhythmia) combined with anxiety-related breathing changes. This is common and often benign - but it must be ruled out clinically because true AFib and other arrhythmias can look identical and require treatment. Please get an ECG done.
