Abstract

We describe a case of a 79-year-old man with pacemaker who presented to the Emergency Department due to asthenia and acute confusional state. He had a history of atrial fibrillation, anemia and colostomy and he was on treatment with diuretics. The electrocardiogram (ECG) showed pacemaker-induced ventricular activity, QRS complexes excessively wide with sine-wave appearance, tall and peaked T waves, without electrically evident atrial activity. Potassium concentration on arterial blood gas analysis was 8.8 mmol/L. ECG abnormalities disappeared after therapy with calcium chloride and spontaneous cardiac activity reappeared.

PlumX Metrics

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
