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

血行感染可出现发热、低血压率增快。

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

室动过是一种超快的跳，会脏的泵血能力。

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

律不齐，医学上称为室动过，是全球突发脏病的主要原因。

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

有副作用了 失眠，沮丧，搏过。

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

这降低脏的兴奋抑制折返快律失常。

The opposite of bradycardia is tachycardia.

动过缓的反面是动过。

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

率超过100次/分钟称为动过。

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

因此这些药物可用于治疗折返动过。

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

动过缓动过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，异常动过可见于休息的人，他们的脏在跳动。

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

例如，睡眠期间动过缓被认为是正常的，体育锻炼期间动过可能是正常的。

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

室动过或V-tach最常见的原因是一个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，它会向处于称为室颤动或室动过的脏输送有针对的、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动过，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，你就能看到脏的节律，你就能分辨出那个人是室颤还是室动过。

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.

这种电冲动从室传导到房的类型，称为顺向传导的房室折返动过（AVRT）；它可以导致很快的室率，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动过，甚至是室纤颤，都是更为严重的律失常，即室搏动太快，以至于不能填充足量的血液。

Automaticity of the purkinje fibers may lead to the development of one or more ectopic pacemaker sites in the ventricles causing ventricular premature beats, tachycardia and fibrillation.

浦肯野纤维的自律可能导致室内一个或多个异位起搏点发展，导致室早搏、动过纤颤。
