In the context of smoking and its effects on heart rate, the correct term related to an elevated heart rate is **tachycardia**. Here's a brief explanation of the terms: 1. **Bradycardia**: This refers to a slower than normal heart rate, typically below 60 beats per minute. 2. **Tachyvasculosis**: This is not a standard medical term and may be a misinterpretation or a less common term. 3. **Hypervolemia**: This refers to an increased volume of blood in the body, which can lead to hypertension but is not directly related to heart rate. 4. **Tachycardia**: This is the correct term for an elevated heart rate, typically defined as a heart rate over 100 beats per minute. Therefore, smoking can lead to hypertension caused by an elevated heart rate or **tachycardia**.
