Laboratory tests and other checks

ECG performance

1. ventricular fibrillation or flutter

2. Ventricular arrest (ventricular rest)

3. Mechanical separation of the heart.

Diagnostic points

Heart failure, pulse can not touch, blood pressure measured; sudden loss of consciousness, limbs twitch, cardiac arrest 5 to 10 seconds, patients with syncope, stop 15 to 20 seconds, sudden loss of consciousness, systemic convulsions, patients that Coma; breathing intermittent, sigh-like, then stop, more than 20 to 30 seconds after the stop; coma, occurred in the heart after 30 seconds; pupil scattered in the heart after 30 ~ 60 seconds, 1 ~ 2 Minutes after the pupil fixed, followed by a variety of shallow reflection disappeared.
