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.
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.
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.
Unlike cardiac arrest, a heart attack is a circulation problem. When circulation is blocked or cut off in some way and blood is no longer supplied to the heart muscle, this can damage that muscle ...
Pulseless electrical activity (PEA) is a form of cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not.Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests [1] and about 50% of in-hospital cardiac arrests.
What causes cardiac arrest? There are many potential causes of cardiac arrest. According to the Mayo Clinic, the most common cause is irregular heart rhythm called ventricular fibrillation, ...
