Key Takeaways
- Palpitations feel like a skipped beat, fluttering, or rapid pounding in the chest.
- Hyperthyroidism (high T3/T4) accelerates heart rate and causes frequent palpitations.
- Low Potassium or Magnesium disrupts electrical conduction in heart muscle.
- Accompanying chest pain or dizziness requires immediate medical attention.
Palpitations stem from benign triggers (caffeine, anxiety) or medical conditions (thyroid hyper-function, electrolyte imbalance, arrhythmia).
Heart palpitations involve an awareness of your heartbeat that feels unusually fast, irregular, or forceful.
### Common Physiological & Medical Triggers
1. **Hyperthyroidism**: Elevated thyroid hormones sensitize heart tissue to adrenaline.
2. **Electrolyte Imbalance**: Low Potassium (Hypokalemia) or low Calcium disrupts cardiac action potentials.
3. **Anemia**: Reduced hemoglobin causes the heart to pump faster to deliver sufficient oxygen.
4. **Caffeine, Stress & Anxiety**: Excess stimulants trigger sympathetic nerve arousal.
