What are the risks associated with a high heart rate?

Elevated heart rate, known as tachycardia, can have various adverse effects on health when it persists over a long period:

1. A high heart rate increases the workload on the heart, causing it to contract and relax more frequently. Over time, this may lead to cardiac muscle fatigue and increase the risk of cardiovascular diseases.

2. Tachycardia can impair the heart's pumping function, reducing effective blood ejection and affecting blood supply to the entire body, which may result in symptoms such as dizziness, fatigue, and fainting.

3. A high heart rate can also lead to insufficient oxygen supply to body tissues, causing symptoms like fatigue and dizziness. In severe cases, it may even trigger shock. Additionally, a rapid heart rate may increase the risk of arrhythmias, such as ventricular premature contractions, atrial premature contractions, and atrial fibrillation. These arrhythmias can severely impair cardiac function and potentially be life-threatening.

For tachycardia, timely medical attention is recommended. In daily life, maintaining a healthy lifestyle—including regular sleep patterns, moderate exercise, balanced nutrition, and avoiding excessive fatigue and mental stress—is advised.
