Understanding Heart Rhythm
Introduction
Heart rhythm refers to the pattern and speed of electrical impulses that regulate your heartbeat. A normal heart rhythm ensures that the heart pumps blood effectively to the body.
Normal Heart Rhythm (Sinus Rhythm)
- The heart typically beats 60-100 times per minute at rest.
- The electrical impulse originates in the sinoatrial (SA) node , the body's natural pacemaker.
- The impulse travels through the heart's electrical system, ensuring a coordinated contraction.
Abnormal Heart Rhythms (Arrhythmias)
When the heart's rhythm is too fast, too slow, or irregular, it is called an arrhythmia. Some common types include:
- Bradycardia (Slow Heart Rate) – Below 60 beats per minute. Can cause dizziness, fatigue, and fainting.
- Tachycardia (Fast Heart Rate) – Over 100 beats per minute. Can be due to stress, fever, or heart disease.
- Atrial Fibrillation (AFib) – An irregular and often rapid heartbeat, increasing the risk of stroke.
- Ventricular Tachycardia – A dangerous, fast rhythm from the ventricles, which may lead to cardiac arrest.
Causes of Arrhythmias
- Heart disease or previous heart attack
- High blood pressure
- Imbalances in electrolytes (e.g., potassium, magnesium)
- Excessive caffeine, alcohol, or drug use
- Stress or anxiety
- Thyroid disorders
Diagnosis and Treatment
- Diagnosis: ECG (electrocardiogram), Holter monitor, stress test
- Treatment: Lifestyle changes, medications (e.g., beta-blockers), pacemakers, or procedures such as catheter ablation .
Takeaway
Heart rhythm is essential for normal heart function. If you experience palpitations, dizziness, or fainting, consult your doctor.

If you or your loved ones experience any of these symptoms, you should consult a doctor in time. Remember that self-medication can be dangerous, and timely diagnosis will preserve the quality and life expectancy.
The heart is an organ that does not know how to "keep silent" if something goes wrong. Chest pain, shortness of breath, swelling, dizziness, and rhythm disturbances are the symptoms that require our attention. The best prevention of heart disease is careful attention to your health, regular checkups with a doctor, and a healthy lifestyle. Take care of your heart, and it will serve you for many years!
