Sudden death is a natural occurrence, unexpectedly sudden death. World Health Organization 6 hours after the onset of death as sudden death. Sudden death can be divided into two categories of cardiac and noncardiac, and sudden cardiac death is the most common cause of natural death, accounting for about 50%, sudden cardiac death in more than half of coronary heart disease caused.
Usually no serious symptoms, sudden fainting, unconscious, pupil scattered large, inch mouth, people welcome, take veins are no, lips face green and purple cold.
Sudden death in patients with coronary heart disease usually have few symptoms, can occur at any time and most occur in the hospital, the survival of patients with prodromal symptoms and less specific and lack of specificity, such as: chest pain, fatigue, difficulty breathing, dizziness, palpitations, Recent frequent angina pectoris, or angina associated with ventricular premature beats, QT interval extension is a certain specificity, may occur sudden cardiac death.
Sudden death in coronary heart disease occurs cardiac arrest is a sign of clinical death, the most important feature is the complete loss of consciousness. Sudden cardiac loss, limbs twitching, cardiac arrest 5 to 10 seconds, patients with syncope, stop 15 to 20 seconds, the heart rate of the heart, Sudden loss of consciousness, systemic convulsions, patients that coma; ③ breathing intermittent, sigh-like, then stop, more than 20 to 30 seconds after stopping; ④ coma, occurred in the heart after 30 seconds; ⑤ 30 ~ 60 seconds after the heart arrest, 1 to 2 minutes after the pupil fixation, followed by a variety of shallow reflection disappeared.
Laboratory tests and other checks
1. ventricular fibrillation or flutter
2. Ventricular arrest (ventricular rest)
3. Mechanical separation of the heart.
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.
