How Dehydration Affects Resting Heart Rate and ECG
Dehydration forces the heart to pump harder, increasing resting heart rate. This topic will explain the physiological mechanism behind it. It will also describe how ECG readings may reflect tachycardia caused by fluid imbalance. The article will emphasize hydration as a simple yet powerful heart-protective habit. Readers will understand how ECG monitoring can differentiate temporary increases from serious rhythm disturbances.
