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.

While on telemetry monitoring he suffered cardiac arrest and was resuscitated. What ECG finding may have contributed to (or precipitated) the cardiac arrest? After resuscitation and defibrillation , there were no more episodes of TdP. Below is the patient’s 12 lead ECG following defibrillation.

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.

Case Report: Four cases of cardiac sarcoidosis in patients with inherited cardiomyopathy—a phenotypic overlap, co-existence of two rare cardiomyopathies or a second-hit disease

DECEMBER 18, 2023

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?

The patient was unconscious BEFORE the cardiac arrest, at the same time that she had strong pulses. Therefore, cardiac arrest is NOT the etiology of the coma. Furthermore, ischemic arrests (from OMI) are almost always initially due to V Fib arrest, though when arrest is prolonged, eventually VF becomes PEA.
