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。

Ventricular tachycardia is a super-fast heartbeat that affects the organ's ability to pump blood.

室性心动过速是一种超快的心跳，会影响心脏的泵血能力。

An irregular heartbeat, known medically as ventricular tachycardia, is a major cause of sudden heart attacks worldwide.

心律不齐，医学上称为室性心动过速，是全球突发心脏病的主要原因。

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

有副作用了 失眠，沮丧，心搏过速。

This reduces the heart's excitability and suppresses reentrant tachycardia.

这降低心脏的兴奋性和抑制折返性快速性心律失常。

All right. Super ventricular tachycardias. Get me Adenosine, one milligram, push.

好了 是心室上心跳过速 1毫克腺苷 静脉注射。

The opposite of bradycardia is tachycardia.

心动过缓的反面是心动过速。

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

心率超过100次/分钟称为心动过速。

Hence the use of these drugs for treating reentrant tachycardia x'.

因此这些药物可用于治疗折返性心动过速。

Sinus bradycardia and sinus tachycardia may be normal or clinical depending on the underlying cause.

窦性心动过缓和窦性心动过速可能是正常现象或临床病变，具体取决于根本原因。

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

但是，异常心动过速可见于休息的人，他们的心脏在跳动。

For example, sinus bradycardia is considered normal during sleep and sinus tachycardia may be normal during physical exercises.

例如，睡眠期间窦性心动过缓被认为是正常的，体育锻炼期间窦性心动过速可能是正常的。

Ventricular tachycardia or V-tach is most commonly caused by a single strong firing site or circuit in one of the ventricles.

室性心动过速或V-tach最常见的原因是一个心室内有强放电部位或电路。

But prolonged repolarization z' may increase the risk of torsades de point a type of tachycardia caused by after depolarizations.

但是延长了的复极化 z’可能会增加由去极化后引起的尖端扭转型室速的风险。

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.

除颤器是一种机器，它会向处于称为心室颤动或室性心动过速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速，甚至几小时内进展到低血压、休克，乃至死亡。

Sinus tachycardia: when the SA node fires more than 100 times per minute generating a faster heart rate of greater than 100 beats per minute.

当SA结放电超过100次/分钟时，产生大于100次/分钟的更快心率。

When it's hooked up, you'll be able to see the rhythm that the heart is in, you'll be able to tell is that person in ventricular fibrillation or ventricular tachycardia.

当它连接起来时，你就能看到心脏的节律，你就能分辨出那个人是室颤还是室性心动过速。

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速（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速，甚至是心室纤颤，都是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。
