Cardiac dysrhythmias

Cardiac dysrhythmias, also known as arrhythmias, are abnormal heart rhythms that can affect the heart's rate or rhythm. They can be classified into several types, including:

1. **Atrial Fibrillation (AF):** Rapid, irregular contractions of the atria, leading to an irregular heartbeat.

2. **Atrial Flutter:** Regular but often rapid contractions of the atria.

3. **Supraventricular Tachycardia (SVT):** Episodes of rapid heart rate originating above the heart's ventricles.

4. **Ventricular Tachycardia (VT):** Rapid heartbeat originating in the heart's lower chambers (ventricles).

5. **Ventricular Fibrillation (VF):** Chaotic, rapid heartbeat in the ventricles, which can be life-threatening.

6. **Bradycardia:** Abnormally slow heart rate.

7. **Premature Contractions:** Early heartbeats that can originate in the atria (premature atrial contractions) or ventricles (premature ventricular contractions).

8. **Long QT Syndrome:** A rare condition affecting the heart's electrical activity, potentially leading to fast, chaotic heartbeats.

Diagnosis involves electrocardiograms (ECGs), Holter monitors, event monitors, and other cardiac tests. Management depends on the type and severity and may include medications, lifestyle changes, catheter ablation, or implantable devices like pacemakers or defibrillators.

It's crucial for individuals with cardiac dysrhythmias to consult with healthcare professionals for proper diagnosis and personalized treatment plans.
