Heart Palpitations: Common Triggers, Risks & Treatment Options | Dr. P L N Kapardhi
Heart palpitations are among the most common reasons people visit a cardiologist. Many describe them as a fluttering, pounding, or racing sensation in the chest. For some, they occur only occasionally and last for a few seconds. For others, they may feel alarming, prolonged, and sometimes accompanied by dizziness or chest pain.
The important question patients ask is: “Are palpitations harmless or do they indicate a serious heart problem?”
As Dr. P L N Kapardhi, one of the Best Cardiologist in Hyderabad, explains:
“Most palpitations are related to lifestyle or stress. But in some cases, they may be an early warning sign of arrhythmia, valve disease, or heart muscle weakness. The key is knowing when to get evaluated.”
This blog will help you understand the causes, symptoms, diagnosis, and treatment of palpitations — and when you should seek expert care.
What Are Heart Palpitations?
Heart palpitations are sensations where you become more aware of your heartbeat. They can feel like:
- Skipped beats
- Extra beats
- A rapid or pounding heartbeat
- A fluttering sensation in the chest
They can occur at rest, during activity, or even when lying down quietly.
In most cases, palpitations are harmless and linked to lifestyle triggers such as stress, caffeine, or lack of sleep. However, in some cases, they may signal an underlying heart rhythm disorder (arrhythmia) or structural heart disease.
Causes of Heart Palpitations
Palpitations can be caused by a wide range of factors. Some are non-cardiac and harmless, while others are cardiac-related and more serious.
| Causes (Category) | Examples |
| Lifestyle / Non-Cardiac | Stress, anxiety, caffeine, nicotine, alcohol, dehydration, strenuous exercise, certain medications (e.g., asthma inhalers, decongestants) |
| Hormonal / Medical Conditions | Thyroid disease, anaemia, low blood sugar, fever, pregnancy, menopause, electrolyte imbalances |
| Cardiac Causes | Arrhythmias (Atrial Fibrillation, Supraventricular Tachycardia, Ventricular Tachycardia), Heart valve problems, Heart failure, Previous heart attack, Cardiomyopathy |
Symptoms That May Accompany Palpitations
Palpitations themselves are a symptom. However, they can be accompanied by other warning signs.
| Harmless Symptoms | Concerning Symptoms |
| Fluttering after coffee or stress | Chest pain or pressure |
| Mild skipped beats at rest | Dizziness or fainting |
| Brief pounding during exercise | Shortness of breath |
| Occasional awareness of heartbeat | Sweating, extreme fatigue |
| No other associated symptoms | Palpitations lasting several minutes to hours |
Harmless vs. Serious Palpitations – How to Tell the Difference
Not all palpitations require medical intervention. Distinguishing between harmless and serious ones is critical.
| Harmless Palpitations | Serious Palpitations |
| Triggered by caffeine, stress, or lack of sleep | Occur without obvious trigger |
| Short-lived (few seconds) | Prolonged or frequent episodes |
| No associated chest pain, fainting, or breathlessness | Associated with fainting, chest pain, or difficulty breathing |
| Often disappear with lifestyle modifications | May indicate arrhythmias or heart valve disease |
| Common in healthy individuals | Common in those with heart disease, diabetes, hypertension |
👉Key takeaway: If palpitations are persistent, worsening, or associated with severe symptoms, consult a cardiologist immediately.
When Should You See a Doctor?
According to Dr. P L N Kapardhi, you should consult a heart specialist if :
Chest pain or tightness
- Shortness of breath
- Dizziness or fainting
- Very rapid or irregular heartbeat
- History of heart disease or valve problems
- Family history of sudden cardiac death
How Are Palpitations Diagnosed?
Tests commonly recommended by Dr. P L N Kapardhi include:
- Medical History & Physical Exam – Understanding triggers, family history, and associated conditions.
- Electrocardiogram (ECG/EKG) – Captures heart’s electrical activity.
- Holter Monitor – Portable ECG worn for 24–48 hours to detect intermittent arrhythmias.
- Event Recorder / Implantable Loop Recorder – For long-term monitoring.
- Echocardiogram – Ultrasound to check heart valves, chambers, and pumping function.
- Blood Tests – To check thyroid function, electrolytes, and anaemia.
- Stress Test / Exercise ECG – To evaluate palpitations during physical exertion.
Treatment Options for Heart Palpitations
Treatment depends on the cause:
Lifestyle Modifications (First-line for harmless palpitations)
- Reduce caffeine, alcohol, and nicotine
- Manage stress through yoga, meditation, or breathing exercises
- Stay hydrated and maintain electrolyte balance
- Get adequate sleep
Medical Management
- Medications to control heart rate and rhythm (e.g., beta-blockers, antiarrhythmics)
- Treat underlying conditions like thyroid disease or anaemia
Interventional / Advanced Treatment
- Catheter Ablation – To treat arrhythmias such as atrial fibrillation or supraventricular tachycardia
- Pacemaker / ICD – For patients with slow heart rate or risk of sudden cardiac arrest
- Valve Repair/Replacement – If palpitations are linked to structural heart valve disease
Can Palpitations Be Prevented?
Yes, many triggers can be avoided. Practical steps include:
- Limiting caffeine and alcohol
- Avoiding over-the-counter stimulants (e.g., nasal decongestants)
- Maintaining heart-healthy diet and exercise routine
- Managing blood pressure, diabetes, and cholesterol
- Regular heart check-ups, especially if you have a family history of heart disease
