The causes of cardiac arrest are lesions of the heart muscle (myocardium), which entail a violation of its main (contractile) function. These include:
Ischemic heart disease - angina pectoris (spasm of the coronary arteries), myocardial infarction, arrhythmias (heart rhythm disturbances).
Damage to the heart valves.
Myocarditis, endocarditis (inflammatory diseases of the lining of the heart).
Cardiomyopathies (changes in the shape and dysfunction of the myocardium).
Aortic dissection aneurysm (dissection of the vascular wall of the largest artery, leading to its rupture).
Cardiac tamponade (the heart seems to “choke” on its own blood).
Treatment for cardiac arrest is resuscitation that includes:
Restoring airway patency.
Artificial respiration or mechanical ventilation (artificial lung ventilation).
Restoration of blood circulation (closed heart massage).
And which organ or system in the body can carry out a complex of resuscitation measures !?
Maybe. And it restarts. At least several times in the life of any person, and in a person with severe arrhythmias - maybe several times a day. If we analyze daily cardiograms (the so-called holter), then in 10-15% of cases there are intervals of cardiac arrest - skipping one or two or three beats. And in case of serious lesions, such as extensive heart attacks or AHF - the body tries to start a stopped heart to the last - another question is that sometimes it cannot do this without help. Another question is a more or less prolonged stop (more than one and a half to two minutes) - the brain itself begins to experience serious oxygen starvation and loses the ability to independently form a triggering impulse - and here there is no chance without massage, electricity, or some nito adrenaline in the muscle.
