The underlying causes of sudden cardiac arrest can result from cardiac and non-cardiac etiologies. The most common underlying causes are different, depending on the patient's age. Common cardiac causes include coronary artery disease , non-atherosclerotic coronary artery abnormalities, structural heart damage, and inherited arrhythmias.
Cardiac arrest can also occur after a hard blow to the chest at a precise moment in the cardiac cycle, which is known as commotio cordis. Other traumatic events such as high speed car crashes can cause sufficient structural damage to induce arrest.
Arrhythmias are the main cause of cardiac arrest but can be triggered by other cardiac events such as heart attacks. Other risk factors include coronary heart disease, heart valve disease, and ...
What causes cardiac arrest in athletes? Autopsies found no heart defects in the majority of those who died. Most likely in these cases, there was an electrical short circuit, Harmon said.
Traumatic cardiac arrest is a complex form of cardiac arrest often derailing from advanced cardiac life support in the sense that the emergency team must first establish the cause of the traumatic arrest and reverse these effects, for example hypovolemia and haemorrhagic shock due to a penetrating injury.
Cardiac arrest results from electrical disturbances that cause the heart to suddenly stop beating the way it should. In cardiac arrest, death can result quickly if steps aren’t taken right away.
Other issues affecting lethality are frequency, which is an issue in causing cardiac arrest or muscular spasms. Very high frequency electric current causes tissue burning, but do not stimulate the nerves strongly enough to cause cardiac arrest (see electrosurgery). Also important is the pathway: if the current passes through the chest or head ...
One other thing that can potentially cause cardiac arrest is myocarditis, but according to Panhwar, myocarditis has to be acute and severe enough to trigger cardiac arrest. Most people will ...
