Introduction
A heart rate in the "100s" refers to over 100 beats per minute. Normally, resting heart rate ranges between 60 and 100 beats per minute. A heart rate exceeding 100 beats per minute is generally considered abnormal and classified as tachycardia. It may be caused by factors such as sleep deprivation, dehydration, supraventricular tachycardia, sinus tachycardia, or hyperthyroidism. Patients are advised to seek appropriate medical treatment as directed by a healthcare provider.

Under normal circumstances, a heart rate in the "100s" refers to more than 100 beats per minute. The normal resting heart rate ranges from 60 to 100 beats per minute. A heart rate exceeding 100 beats per minute is generally considered abnormal and classified as tachycardia. This may be caused by factors such as sleep deprivation, dehydration, supraventricular tachycardia, sinus tachycardia, or hyperthyroidism. Patients are advised to follow medical guidance for appropriate treatment. Specific causes are analyzed as follows:

1. Sleep Deprivation

Sleep deprivation can lead to an increased heart rate, primarily because lack of sleep stimulates excessive secretion of cortisol, resulting in elevated heart rate and blood pressure. Patients should pay attention to maintaining adequate sleep and relaxing the body.

2. Dehydration

Dehydration often leads to low blood pressure, forcing the heart to work harder, which may result in tachycardia. This condition is particularly noticeable after heavy sweating. It is recommended that patients promptly rehydrate to reduce potential health risks.

3. Supraventricular Tachycardia (SVT)

Supraventricular tachycardia is a reentrant arrhythmia caused by an accessory conduction pathway in the heart. Patients may take medications such as propafenone hydrochloride tablets or amiodarone hydrochloride tablets as directed by a physician.

4. Sinus Tachycardia

Sinus tachycardia occurs when the sinoatrial node generates electrical impulses at an abnormally high frequency due to certain factors, causing the heart rate to exceed 100 beats per minute. Patients may use medications such as warfarin sodium tablets or verapamil hydrochloride tablets under medical supervision.

5. Hyperthyroidism

In patients with hyperthyroidism, the increased heart rate results from the stimulating effects of excess thyroid hormones on the heart, leading to tachycardia. Some patients may develop paroxysmal or persistent atrial fibrillation. Treatment may include medications such as levothyroxine sodium tablets or thyroid extract tablets, as prescribed by a doctor.

In addition, tachycardia may also be caused by rheumatic heart disease. If patients experience any discomfort, they should seek prompt medical evaluation and receive targeted treatment to avoid delays in managing their condition.
