Next, with a bloodstream infection, there may be fever and hypotension and tachycardia.

血行感染可出现发热、低血压和心率增快。

For example, everyone has a heartbeat, right? and tachycardia is a fast heartbeat.

举个例子，每个人都有心跳，而心动过则心跳得太快。

There's gonna be side effects. Insomnia, depression, tachycardia...

有副作用了 失，，心搏过。

The opposite of bradycardia is tachycardia.

心动过缓的反面心动过。

A heart rate faster than 100 beats per minute is termed tachycardia.

心率超过100次/分钟称为心动过。

But, abnormal tachycardia is seen in a person who is at rest, yet their heart is racing.

，异常心动过可见于休息的人，他们的心脏在跳动。

A defibrillator is a machine that delivers a targeted, measured amount of electricity to a heart that is either in something called ventricular fibrillation or ventricular tachycardia.

除颤器一种机器，它会向处于称为心室颤动或室性心动过的心脏输送有针对性的、可测量的电量。

The fast-moving infection and massive tissue destruction can lead to fever and tachycardia, and can even progress to hypotension, shock, and eventually death - within just a few hours.

进展极快的感染以及大量组织坏死导致发热和心动过，甚至几小时内进展到低血压、休克，乃至死亡。

This type where it goes up from ventricle to atrium, is called Atrioventricular reentrant tachycardia (or AVRT) with orthodromic conduction, and can lead to very high ventricular rates, between 200 and 300 bpm.

这种电冲动从心室传导到心房的类型，称为顺向传导的房室折返性心动过（AVRT）；它可以导致很快的心室率，达到每分钟200-300次。

In rare situations, an ectopic focus can trigger ventricular tachycardia or even ventricular fibrillation, which are more serious arrhythmias where the ventricles beat too quickly to fill up with an adequate amount of blood.

罕见情况下，异位起搏点会引发室性心动过，甚至心室纤颤，都更为严重的心律失常，即心室搏动太快，以至于不能填充足量的血液。
