Heart Rhythm Chaos: Understand Arrhythmia Dangers
13 Sep
Summary
- Arrhythmia, an irregular heartbeat, can range from harmless to dangerous.
- The heart's electrical system controls rhythm; malfunctions cause arrhythmias.
- Atrial fibrillation is common and can lead to strokes.
The heart's normal rhythm ensures efficient blood distribution, beating over 100,000 times daily. When this rhythm becomes too fast, slow, or irregular, it's termed arrhythmia, which can vary from harmless to life-threatening.
The heart's electrical conduction system, originating from the sinus node, dictates its beat. Irregular impulses or abnormal generation speed can lead to various arrhythmias.
Common arrhythmias include supraventricular tachycardia (rapid beats from above the ventricles), atrial fibrillation (quivering atria leading to irregular beats and potential stroke), atrial flutter (similar to AFib but potentially more regular), premature beats (skipped beats), ventricular tachycardia (dangerous rapid beats from ventricles), and bradycardia (slow heart rate).
Atrial fibrillation is particularly significant due to the risk of blood clots forming, which can travel to the brain and cause a stroke. Patients may require anticoagulant medications and regular monitoring.
Diagnosis typically involves ECG, Holter monitoring, or event monitoring, with echocardiography used to assess heart disease. Proper diagnosis is essential as each arrhythmia has specific treatments.
