A rare cause of sudden cardiac arrest: primary cardiac lymphoma

Fatal chloroquine poisoning: a rare cause of sudden cardiac arrest.

electrocardiogram (ECG) showed sinus tachycardia of 102 beats/minute with a QT interval (QTC) of 372 ms. Potassium levels were corrected overnight with 120 mmol/L of IV potassium. Her progress in intensive care unit (ICU) was poor. Neurological exam post-arrest showed fi xed and dilated pupils, negative corneal and oculocephalic reflexes and Glasgow Coma Scale (GCS) of 3. She remained haemodyna...

Sudden Cardiac Arrest

How to diagnose the cause of sudden cardiac arrest.

Sudden cardiac death or sudden cardiac arrest (SCA) is defined as natural death that occurs within an hour of the onset of acute symptoms or during sleep due to a primary cardiac cause. Most cases of SCA are attributable to coronary artery disease, with occult cardiomyopathy or inheritable arrhythmic syndromes accounting for a minority of SCA. Diagnosing the cause of SCA has potential implicati...

Sudden Cardiac Arrest and Rare Genetic Variants in the Community.

BACKGROUND Sudden cardiac arrest (SCA) ranks among the most common causes of death worldwide. Because SCA is most often lethal, yet mostly occurs in individuals without previously known cardiac disease, the identification of patients at risk for SCA could save many lives. In unselected SCA victims from the community, common genetic variants (which are not disease-causing per se, but may increas...
