What are Cardiac Arrhythmias? Understanding Irregular Heart Rhythms
Cardiac arrhythmias are conditions that disrupt the normal rhythm of the heart, causing it to beat too fast, too slow, or irregularly. These disturbances occur due to malfunctions in the heart’s electrical system. While some arrhythmias are harmless, others can be serious or life-threatening, affecting how efficiently the heart pumps blood to the body. They can interfere with daily life, causing symptoms that impact physical and emotional well-being.
Symptoms of Cardiac Arrhythmias
Recognizing the symptoms of cardiac arrhythmias is crucial for timely diagnosis and intervention. Common symptoms include:
- Palpitations: Sensation of a racing, fluttering, or pounding heart.
- Dizziness or Lightheadedness: A result of reduced blood flow to the brain.
- Shortness of Breath: Especially during activity or when lying down.
- Fatigue: Feeling unusually tired, even after minimal exertion.
- Chest Pain or Discomfort: Can occur if the arrhythmia affects blood flow to the heart.
