Abnormal heart rhythm

Definition

Abnormal heart rhythm, also known as arrhythmia, is a condition where the heart beats too quickly, too slowly, or irregularly. This can affect the efficiency of the heart's ability to pump blood and may have neurological implications due to altered blood flow to the brain.

5 Must Know Facts For Your Next Test

1. Abnormal heart rhythms can disrupt blood flow to the brain, impacting neurological function.
2. Common types of arrhythmias include atrial fibrillation, bradycardia, and tachycardia.
3. Electrolyte imbalances from poor nutrition can trigger or worsen abnormal heart rhythms.
4. Certain nutrients like potassium and magnesium are crucial for maintaining a regular heart rhythm.
5. Monitoring and managing dietary intake is essential in patients with a history of arrhythmias to prevent exacerbation.
