     These symptoms can be alarming and may lead you to worry about having heart disease. However, did you know that such symptoms may arise from other causes unrelated to heart disease, such as panic disorder? Today, we will clarify the differences between palpitations caused by panic disorder and those resulting from cardiac arrhythmia, to help you better understand the cause of your symptoms and take proper care of your health. Do not let health-related anxiety interfere with your peace of mind.

 

Panic Disorder

Panic disorder is a mental health condition characterized by sudden and intense episodes of fear or panic that can occur at any time, often more severe than ordinary stress. A panic attack typically lasts 10–20 minutes, but in some cases, it may persist for hours. Common symptoms include:

 

  • Rapid heartbeat, shortness of breath, or a sensation of suffocation
  • Intense fear that may cause physical immobility
  • Dizziness or nausea
  • Sweating, trembling hands or feet
  • Chest tightness and difficulty breathing
  • Anxiety or fear of dying, accompanied by a sense of loss of control over one’s life
  • Avoidance of situations that previously triggered fear

 

Treatment of Panic Disorder

Panic disorder is treatable and potentially curable through several approaches that aim to manage symptoms and prevent recurrence:

 

1. Physical Treatment

  • Medication: Doctors may prescribe drugs to correct chemical imbalances in the brain.
  • Blood tests: To rule out other possible medical causes of the symptoms.

 

2. Psychological Treatment

  • Psychotherapy: Helps patients understand and manage anxiety-inducing thoughts and emotions.
  • Behavioral therapy: Focuses on learning relaxation techniques and coping with triggering situations.
  • Breathing exercises: Assist in calming the mind and reducing anxiety levels.

 

3. Support from Others

  • Understanding: Family and friends should learn about panic disorder to offer encouragement, create a supportive environment, and help the patient feel secure.

What Is Cardiac Arrhythmia?

Cardiac arrhythmia refers to abnormalities in the heart’s rhythm, which can manifest in two main forms:

 

  • Abnormal heart rate: The heart beats either too slowly or too rapidly.
  • Irregular heartbeat: The rhythm may be erratic or inconsistent, such as starting and stopping irregularly.

 

 


Some patients may experience both conditions simultaneously, such as alternating between rapid and slow heartbeats or an irregular rhythm.

 

 

Symptoms of Cardiac Arrhythmia

Symptoms of arrhythmia can vary widely, from being asymptomatic to presenting severe warning signs, including:

 

  • Fluttering or irregular heartbeats
  • Heart rate that is too fast or too slow
  • Chest pain
  • Shortness of breath
  • Fainting or loss of consciousness
  • Palpitations, lightheadedness, or dizziness

 

 


These symptoms warrant immediate medical attention for diagnosis and to prevent complications.

 

 

Types of Arrhythmias

Arrhythmia involves abnormal heart rhythms that can be categorized into:

 

  • Bradycardia: Heart rate slower than 60 beats per minute
  • Tachycardia: Heart rate faster than 100 beats per minute

 

Types of Tachycardia include

  • Non-life-threatening tachycardia: Such as supraventricular tachycardia (SVT) and ventricular tachycardia (VT)
  • Life-threatening tachycardia: Such as ventricular fibrillation (VF), which can cause unconsciousness and death if untreated
  • Skipped or irregular beats: May cause palpitations, fainting, or uneasiness
  • Atrial fibrillation (AF): The most common arrhythmia, leading to palpitations and increased risk of blood clots

 

Diagnosing Cardiac Arrhythmia

Diagnosing arrhythmia can be challenging due to the variability in symptoms and their duration—some last only seconds, while others may persist for hours. Accurate diagnosis requires capturing the heart’s electrical activity during symptoms using the following methods:

 

1. Electrocardiogram (EKG/ECG)

     A basic test that records the heart's electrical signals and presents them as a graph. Best used when symptoms occur in a clinical setting.

 

2. Holter Monitoring

     A portable device worn for 24–48 hours to continuously record the heart’s activity, suitable for patients with daily or near-daily symptoms.

 

3. Multiday Patch Holter

     A patch-based device placed on the chest to record heart activity over several days is ideal for intermittent symptoms.

 

4. Event Recorder/Loop Recorder

     A portable device for patients with infrequent symptoms (e.g., once or twice a month). The patient activates it during symptom episodes.

 

5. Implantable Loop Recorder (ILR)

     A subcutaneous device implanted beneath the left chest wall, suitable for patients with rare but severe symptoms such as unexplained fainting.

 

6. Electrophysiology (EP) Study

     Involves threading catheters through blood vessels into the heart to assess its electrical system and induce arrhythmias. Recommended when other tests fail to detect the abnormality.

Treatment of Cardiac Arrhythmia

     Arrhythmias have various causes and levels of severity, requiring individualized treatment. Initial management includes addressing modifiable factors, such as avoiding stimulants and treating underlying diseases. If symptoms persist, direct intervention may be necessary:

 

1. Pacemaker

     Implanted under the collarbone, it regulates the heart rate when the heart beats too slowly or pauses temporarily.

 

2. Automated Implantable Cardioverter-Defibrillator (AICD)

Also implanted under the skin, this device delivers high-energy shocks to correct life-threatening arrhythmias.

 

3. Radiofrequency Catheter Ablation (RFCA)

     A minimally invasive procedure using heat energy to destroy the abnormal heart tissue causing the arrhythmia.

 

4. Cryoablation

     A similar approach to RFCA but uses cold energy to target abnormal tissue. It is equally effective, less time-consuming, and may result in less pain or tissue damage.

Self-Screening: Panic Disorder vs. Cardiac Arrhythmia

Palpitations are common and may result from several causes, primarily panic disorder and cardiac arrhythmia.

 

Initial Differentiation

  • Panic Disorder: Often triggered by fear or anxiety, accompanied by symptoms such as hyperventilation, trembling hands, excessive sweating, and a fast but regular heartbeat.
  • Cardiac Arrhythmia: Caused by structural or functional heart abnormalities, often with irregular, fast, or slow heartbeats, and may include dizziness, fainting, or chest pain.

 

Accurate Diagnosis

Definitive diagnosis requires capturing an ECG during symptom episodes. The appropriate diagnostic method depends on the specific characteristics of each patient's symptoms.

 

Important Reminders

  • Observing symptoms can provide preliminary insight into the cause of palpitations.
  • A correct diagnosis must be made by a medical professional.
  • Do not panic if you experience palpitations—seek medical advice for proper evaluation and treatment.

 

 


Ultimately, distinguishing between palpitations caused by panic disorder and those from arrhythmia can be difficult for patients. Consulting a physician is the most crucial step in obtaining an accurate diagnosis and appropriate treatment.
