Cardiac arrest was called and advanced life support was undertaken for this patient. The patient was given chest compressions while waiting for the cardiac arrest team to arrive. She spontaneously converted (Defibrillation was not performed). The morning before the cardiac arrest potassium was 4,3.mmol,

He was defibrillated, but they also noticed that he was being internally defibrillated and then found that he had an implantable ICD. He was unidentified and there were no records available After 7 shocks, he was successfully defibrillated and brought to the ED. I wrote the following note in the chart: "V Fib arrest, has ICD.

He was defibrillated into VT. He then underwent dual sequential defibrillation into asystole. But cardiac arrest is a period of near zero flow in the coronary arteries and causes SEVERE ischemia. After cardiac arrest, I ALWAYS wait 15 minutes after an ECG like this and record another. They started CPR.

Hypertrophic cardiomyopathy (HCM) predisposes patients to cardiac arrest (CA). While established major risk factors may warrant the need for primary prevention by implantable cardioverter-defibrillator (ICD), it is unknown if specific electrocardiographic predictors increase the risk of CA.

Cardiac sarcoidosis (CS), a rare condition characterized by non-caseating granulomas, can manifest with symptoms such as atrioventricular block and ventricular tachycardia (VT), as well as mimic inherited cardiomyopathies. An endomyocardial biopsy (EMB) confirmed the diagnosis of cardiac sarcoidosis.

Although one may have all kinds of ischemic findings as a result of cardiac arrest (rather than cause of cardiac arrest), this degree of ST elevation and HATW is all but diagnostic of acute proximal LAD occlusion. This prompted cath lab activation. On arrival to the ED, this ECG was recorded: What do you think?
