ABSTRACT
We present a case with acute coronary syndrome and very unusual QRS widening in the acute phase. The case highlights that non-specific intraventricular conduction delay should be considered as a high risk ECG pattern predicting poor prognosis.

Severe hyperkalemia may be concealed in the electrocardiogram (ECG). We present the case of a critically ill patient with severe bradycardia and the BRASH syndrome. In critically ill patients, double counting of the heart rate is frequently a marker of severe hyperkalemia (Littmann sign). In our case, hyperkalemic double counting only appeared in the ECG performed during percutaneous pacing. The Littmann sign helped with the early recognition of hyperkalemia and the BRASH syndrome.

Hydroxychloroquine is an immunomodulatory drug that has been used to treat malaria and autoimmune diseases such as systemic lupus erythematosus and inflammatory arthritis. The authors conclude the proarrhytmic effects of hydroxychloroquine and the most important signs of drug-induced long QT syndrome. This article is especially relevant and timely due to the more frequent (currently not evidence-based) use of the drug during the 20192020 coronavirus pandemic. Orv Hetil. 2020; 161(17): 689691.

Authors report the case of a patient with drug-induced long QT syndrome. This case highlights the importance of ECG signs of LQTS that may lead to torsade de pointes tachycardia. The patient received the QT prolonging moxifloxacine and the QT remained long even after the offending drug was discontinued. Orv Hetil. 2018; 159(39): 1607-1610.

The Brugada sign may appear as an indication of severe hyperkalemia. This phenomena has recently been called as the "Brugada phenocopy". Hyperthermia and hypothermia may lead to rhabdomyolysis. Rhabdomyolysis is a syndrome characterized by muscle necrosis and the release of intracellular muscle constituents into the circulation. We present a case where rhabdomyolysis-related delayed hyperkalemia showed Brugada sign on the ECG mimicking ventricular tachycardia.
