Anxiety Attack or Heart Arrhythmia? Symptoms, Differences and When to See a Cardiologist in Los Cabos
Feeling your heart race, having difficulty breathing, or experiencing chest pain can be alarming. Many people are unsure whether these symptoms are related to an anxiety attack or a cardiac arrhythmia.
This confusion is common, as both conditions can present similar symptoms. However, correctly identifying the cause is essential to receive appropriate treatment and avoid complications.

At BlueNetHospitals Los Cabos, we evaluate both conditions to provide an accurate diagnosis.


Why are anxiety and arrhythmia often confused?
From a medical perspective, anxiety activates the sympathetic nervous system, releasing hormones such as adrenaline. This leads to an increased heart rate, rapid breathing, and a heightened state of alertness.
On the other hand, a cardiac arrhythmia occurs when the heart’s electrical impulses do not function properly, causing irregular heartbeats that are not always related to stress.
Although the symptoms may seem similar, the underlying cause is different and requires medical evaluation.

What is anxiety?

Anxiety is a natural response of the body to stress or danger. However, when it becomes frequent or intense, it can affect both physical and emotional health.

Symptoms of anxiety
  • A constant sense of danger or worry
  • Nervousness or tension
  • Increased heart rate
  • Sweating
  • Difficulty breathing
  • Sleep problems
  • Fatigue or weakness
What is a cardiac arrhythmia?
A cardiac arrhythmia is a disorder of the heart’s rhythm caused by a malfunction in the electrical impulses that coordinate heartbeats.
This may result in:
  • Fast heartbeats (tachycardia)
  • Slow heartbeats (bradycardia)
  • Irregular heartbeats
At rest, the heart normally beats between 60 and 100 beats per minute.

Symptoms of cardiac arrhythmia

  • Palpitations or irregular heartbeat
  • Chest pain or pressure
  • Shortness of breath
  • Dizziness or fainting
  • Fluttering sensation in the chest
  • Fatigue
Warning signs

  • Severe chest pain
  • Severe difficulty breathing
Differences between anxiety and arrhythmia
Anxiety Arrhythmia
Related to stress or emotions May occur without an emotional trigger
Temporary episodes Can be persistent or recurrent

Intense feeling of fear Relationship between anxiety and arrhythmia

Relationship between anxiety and arrhythmia
Stress and anxiety can increase heart rate and cause palpitations. In most cases, these episodes are temporary.
However, when they are frequent or intense, they may trigger or worsen heart conditions.

Evaluating both emotional and cardiovascular health is essential.

What should you do if you are experiencing palpitations right now?

  • Stop and take deep breaths
  • Avoid caffeine or stimulants
  • Sit or lie down
  • Observe whether symptoms decrease
If symptoms do not improve or are accompanied by chest pain or fainting, go to the emergency room.

How long does an episode last?

  • Anxiety: Minutes to one hour, improves with relaxation
  • Arrhythmia: May last seconds, minutes, or be persistent
Frequent episodes should be evaluated.

Can it occur at rest or at night?
Yes. Both anxiety and some arrhythmias can occur at rest or during the night.

If it happens repeatedly, medical evaluation is important.

How is it diagnosed?
  • Electrocardiogram (ECG) detects electrical abnormalities in the heart
  • Holter monitor records heart rhythm over 24 to 48 hours
  • Echocardiogram evaluates heart structure and function
These tests help determine whether symptoms are cardiac or emotional in origin and define the most appropriate treatment. They are safe and noninvasive.

Additional tests
  • Stress test analyzes the heart during physical activity
  • Tilt table test evaluates fainting episodes
  • Electrophysiological study identifies the source of the arrhythmia
Treatment according to diagnosis
