- Heart palpitations are sensations of fast, pounding, or irregular heartbeats that many patients experience.
- They can be triggered by stress, caffeine, dehydration, or more serious heart conditions like arrhythmia.
- While occasional palpitations can be harmless, frequent or prolonged episodes — especially with dizziness, chest pain, or shortness of breath — warrant evaluation by a cardiologist.
- Dr. Sunny Malhotra offers advanced diagnostic testing, arrhythmia management, and personalized treatment plans to patients in Brampton, Mississauga, Caledon and Milton.
- This blog will help you understand what palpitations feel like, common causes, warning signs, and the heart tests that can uncover the underlying issue.
🫀 What Are Heart Palpitations?
Heart palpitations are the feeling of your heart skipping a beat, fluttering, or beating too fast. Many people describe it as:
- “My heart suddenly flutters”
- “It feels like my heart jumps”
- “My heartbeat feels too fast or irregular”
- “I feel it in my chest or throat”
Palpitations often happen during moments of stress or high activity — but for some, they can be frequent, intense, or disruptive.
🔍 Common Triggers vs. Serious Causes
Common (Benign) Triggers
Many palpitations are harmless and can be caused by:
- Stress or anxiety
- Caffeine or energy drinks
- Alcohol intake
- Smoking or vaping
- Exercise
- Fever
- Dehydration
- Certain medications
If palpitations are occasional and go away quickly, they may not indicate serious heart disease. However…
🚨 When to See a Cardiologist Right Away
Seek immediate medical attention if your palpitations are accompanied by:
- Chest pain or pressure
- Shortness of breath
- Fainting or near‑syncope
- Dizziness or lightheadedness
- Extremely rapid heartbeat that doesn’t subside
These symptoms could signify arrhythmias, structural heart disease, or other urgent cardiac conditions.
❤️ Why Palpitations Happen: Common Heart‑Related Causes
Some heart‑related causes Dr. Malhotra evaluates include:
1. Atrial Fibrillation (AFib)
An irregular rhythm originating from the top chambers (atria). AFib can increase stroke risk if not treated properly.
2. Supraventricular Tachycardia (SVT)
A sudden fast heartbeat that starts and stops abruptly.
3. Premature Ventricular Contractions (PVCs)
Extra heartbeats originating in the heart’s lower chambers.
4. Heart Valve Disease
Poor valve function can strain the heart and cause abnormal rhythms.
5. Coronary Artery Disease
Reduced blood flow to the heart muscle can trigger palpitations and chest discomfort.
